INVESTING IN OUR FUTURE Taking the politics out of transport infrastructure investment Dear Readers, While I feel fairly certain that some of you have read the sub-heading to this editorial with a wry smile and thoughts along the lines of ‘sure, that would be nice, but it won’t ever happen’, I’ll beg your indulgence and push on regardless. After all, even though ‘removing the politics’ from a matter of such national importance may seem somewhat idealistic, or nothing more than an impossible utopian dream, the purpose of this editorial is to highlight what I see as a major issue, and perhaps encourage discussion as to how we can overcome that issue… the consequences of which are affecting us all. Those consequences - choking congestion, rising transport costs, massive environmental impacts and, in our major capitals, travel and commute times that are now some of the worst on the planet – are not only threatening to bring our major capitals and regional centres to a standstill, they can also severely impact our future growth and prosperity. Interestingly, while the previous paragraph seems to hold the sentiments of the electioncycle statements of most, if not all, political parties, it would also seem that that is where the agreement ends. And therein lies the problem. Despite the fact that there seems to be almost universal agreement that our current infrastructure - both in terms of roads, freight and public transport - is, quite literally (and

2 Highway Engineering Australia | Dec 2018/Jan 2019

figuratively, if you wish) choking under the current demands being placed on it, we appear to be unable to achieve any sort of reasonable political consensus as to how we can move forward with a workable, long-term transport infrastructure plan. These issues were once again highlighted in the lead-up to the recent Victorian election, which saw each of the parties pitted against each other in terms of which projects should be given the green light and, perhaps most alarmingly, veiled threats that contracts could be called in to question and possibly cancelled should they be signed – an issue which has previously cost Victorian taxpayers well over $1 billion. What’s more, the arguments aren’t just about which projects should get the go ahead, they’re also about which transport modes we should invest in. Do we invest in roads? Do we invest in public transport? And if we invest in public transport, should it be rail, bus, light rail? What about bike paths? What about pedestrians? What about autonomous vehicles? You get the picture… Unfortunately, the ONLY result of the never-ending political bickering, is that the infrastructure that our nation so desperately needs gets endlessly delayed, and our transport problems continue to get worse. Regardless of your political persuasion (or lack thereof), I would suggest that if you are to look at the current transport infrastructure

crisis, the answer to all of the questions listed above should be a resounding YES… WE NEED ALL OF THIS! We live in a rapidly growing nation, with rapidly expanding capitals and major regional centres, and an increasingly mobile population. Our national freight task continues (and will continue) to grow at significant rate each year, and our population growth is exceeding our historical expectations. Furthermore, none of these issues are going away any time soon. With that in mind, I believe that it falls to us all – regardless of political affiliations and/ or ideological motivations – to work together, honestly and in good faith, to make the investment that we need across the full scope of transport modes, to develop and deliver the infrastructure that our nation so desperately needs. And I’m not talking about an endless array of feasibility studies. I’m referring to actual investment, in actual infrastructure capable of delivering actual results. After all, it doesn’t matter what your political affiliations are when you’re sitting in a traffic jam or there is no public transport for you to catch.

Victorian Government commended for getting on with North East Link The release to market of the early works and primary works packages for Melbourne’s North East Link, two days after the Andrews Government’s re-election, not only marks a major milestone in the delivery of Victoria’s infrastructure pipeline, it is also a move that has been commended by many within the sector – including Roads Australia. “Our members have been marshalling resources in expectation of these packages coming to market, and will welcome the Government’s decisive action on the heels of Saturday’s election result,” says Roads Australia President, David Stuart-Watt. “As we said early in the Victorian campaign, transport was always going to be the big winner in this election. Victorians have made a clear decision on the road and rail solutions they want to see constructed over the next four years and beyond.” Mr Stuart-Watt say while today’s call for expressions of interest is a significant step forward and good news for Victorians and the construction industry, it also highlights the continuing pressure on industry capacity. “There is currently a massive pipeline of work being rolled out along Australia’s eastcoast, and industry resources are becoming more and more stretched,” he says. “Notwithstanding, it’s encouraging to see governments - including Victoria’s - working closely with industry to identify both short and long-term solutions.” Mr Stuart-Watt has also urged the Victorian Government to continue working with industry to develop more flexible contracting arrangements.

“At November’s Transport and Infrastructure Council (TIC) meeting in Sydney, Federal, state and territory ministers endorsed a set of high-level principles that put a more collaborative approach to procurement, project management and risk allocation squarely on state agendas,” he says. “Ministers also undertook to report back within 12 months on actions taken by their jurisdictions to support the high-level principles. “As a member of the Construction Industry Leadership Forum, Roads Australia is keen to continue working with the Victorian Government to identify innovative procurement models and forms of contracting that will achieve the best value and long-term benefit for taxpayer-funded infrastructure projects.” Mr Stuart-Watt said the North East Link project was also good news for Victorians on the employment margins. “The Victorian Government has been at the forefront of social procurement and diversity policies and programs aimed at providing greater training and employment opportunities for women, indigenous, long-term unemployed and disabled Victorians,” he said.

Giving way to the wealthy - faster commutes for those prepared to pay Autonomous vehicles could see privileged road access for those prepared to pay a premium, say Monash University ethicists Professor Robert Sparrow and Dr Mark Howard. Online auctions could determine who gets through an intersection first and faster routes reserved for higher-paying customers,

Professor Sparrow told delegates at the recent Australian Intelligent Transport Systems Summit in Sydney. Autonomous vehicles offer an opportunity to apply free market principles and create ‘market in mobility’ by pricing road access for more efficient use of an increasingly scarce resource. But increased efficiency could come at significant social, ethical and political cost, he warns. An equal place where all users have the same rights and subject to the same laws - no matter what type of car they drive - could become a place where the wealthy can buy their right of way. “The logic of the free market, when unleashed on urban transport, points firmly to pricing journey times - and therefore access to space on the roads - in accordance with the ability to pay,” Prof Sparrow says. “The cars of those who paid lower prices could be made to slow down and move aside in order to allow the cars of those who had paid higher prices to pass them, making the mobility privileges purchased by the wealthy all-too-obvious to the poor.” In feudal times ‘commoners’ were often expected, or forced by law, to make way for the nobility on roads. In the future, algorithms will replace expectations of ‘giving way to the wealthy’ with technology determining traffic flows that provide a daily reminder of someone’s place in society. The prospect of a ‘market in mobility’ would also lead to roads being private, rather than public space, effectively controlled by a small number of companies operating fleets of vehicles. “It would also result in private corporations controlling access to a good - mobility that is itself essential to social and political participation, entrenching the divide between rich and poor. “It’s something governments and policymakers need to carefully consider in their quest for more efficient road networks,” Prof Sparrow adds.


Energy researchers in the hydrogen lab. ©John Nguyen Photography

Australia is a step closer to a new hydrogen production and export industry Australia is a step closer to a new hydrogen production and export industry, following the national science agency’s successful refuelling of two fuel cell vehicles. CSIRO Chief Executive Larry Marshall was one of the first to ride in the Toyota Mirai and Hyundai Nexo vehicles powered by ultra-high purity hydrogen, produced in Queensland using CSIRO’s membrane technology. This technology will pave the way for bulk hydrogen to be transported in the form of ammonia, using existing infrastructure, and then reconverted back to hydrogen at the point of use. It has the potential to fill the gap in the technology chain to supply fuel cell vehicles around the world with low-emissions hydrogen sourced from Australia. The membrane separates ultra-high purity hydrogen from ammonia, while blocking all other gases. It links hydrogen production, distribution and delivery in the form of a modular unit that can be used at, or near, a refuelling station. This means that the transportation and storage of hydrogen - currently a complex and relatively expensive process is simplified, allowing bulk hydrogen to be transported economically and efficiently in the form of liquid ammonia. Recent advances in solar and electrochemical technologies mean renewable hydrogen production is expected to become competitive with fossil fuel-based production, providing an opportunity to decarbonise both the energy and transport sectors while creating new export opportunities. CSIRO Chief Executive Dr Larry Marshall is excited by the prospect of a growing global market for clean hydrogen, and the potential for a national renewable hydrogen export industry, to benefit Australia.

6 Highway Engineering Australia | Dec 2018/Jan 2019

"This is a watershed moment for energy, and we look forward to applying CSIRO innovation to enable this exciting renewablysourced fuel and energy storage medium a smoother path to market," Dr Marshall said. "I'm delighted to see strong collaboration and the application of CSIRO know-how to what is a key part of the overall energy mix." BOC Sales and Marketing Director Bruce Currie congratulated CSIRO on the successful refuelling of hydrogen fuel cell electric vehicles, which proves the effectiveness of CSIRO’s membrane technology from generation, right through to point of use. “BOC’s innovative engineering team are proud to be collaborating with CSIRO researchers on this technology breakthrough, as we focus on advancing the hydrogen economy and global transition towards clean hydrogen for mobility and energy,” Mr Currie said. Following this successful demonstration, the technology will be increased in scale and deployed in several larger-scale demonstrations, in Australia and abroad. The project received $1.7 million from the Science and Industry Endowment Fund (SIEF), which was matched by CSIRO. In addition to its membrane technology, CSIRO is applying its expertise to all stages of the hydrogen technology chain, including solar photovoltaics, solar thermal, grid management, water electrolysis, ammonia synthesis, direct ammonia utilisation via combustion and/or fuel cells, as well as hydrogen production.

First Sydney Growth Trains enter service Downer EDI Limited (Downer) recently announced that the first of 24 new eight-car Sydney Growth Trains (SGT), now also known as Waratah Series 2 trains, have entered passenger service.

The SGT project is being delivered by Downer as part of the NSW Government’s $1.5 billion ‘More Trains, More Services’ program. The Chief Executive Officer of Downer, Grant Fenn, said the Waratah Series 2 trains further improved the passenger experience with their superior design and technology. “Downer is continuing to work with Transport for NSW, our delivery partners and suppliers to provide safe, reliable and comfortable world-class transport solutions for the people of New South Wales,” Mr Fenn said. “Importantly, we have built on the success of the original Waratah train fleet to deliver Sydney’s newest trains in record-time. We understand the transport challenges in New South Wales and the need to increase capacity as quickly as possible with improved passenger comfort and the highest standards of safety.” The new trains will be progressively introduced into service, with the entire fleet delivered by early 2019.

Australia’s eftpos Tap & PayTM fast-tracks for transport

More torque for hydrogen-powered vehicles IDTechEx Research recently published a new report ‘Fuel Cell Vehicles 2019-2029’ which looks at the viability of fuel cells in commercial and passenger vehicles. Fuel cells are commercially successful in stationary applications but commercially unsuccessful in vehicles, beyond a few thousand purchased for material handling vehicles, notably forklifts. A few thousand had been sold as cars by the end of 2017, mostly to institutions on a non-commercial basis. Fuel cell buses and cars are still outsold by a factor of about one hundred by pure electric buses and cars. Fuel cells in off road vehicles, marine and aircraft applications have performed quite well but are not yet adopted in volume. Nevertheless, in recent years a renewed interest in this technology has prompted many companies to develop and market new fuel cell electric vehicles (FCEV), in the hope that this time hydrogen fuel can really ignite a spark in the industry. Toyota and Hyundai, for instance, are now selling their H2-powered passenger cars, and Japan plans to use the 2020 Tokyo Olympics as a huge showroom for the country’s know-how in the hydrogen economy, with 35 hydrogen refuelling stations scheduled to open before the start of the games. At the same time, European firms like Alstom believe that dirty diesel trains can be replaced by cleaner H2-powered ones, as hydrogen is a more cost-effective solution to the expensive conventional rail infrastructure. A few trains are already in operation in the rural part of northern Germany, and if proven successful, fuel cell trains will soon capture more market share at the expense of diesel ones.

The trucking industry is also longing for CO2-free alternatives to diesel engines, which are prone to failure and cost their drivers thousands of dollars each year in fuel. However, Li-ion batteries are not always the best solution for that, as charging a 1 MWh battery pack can take several hours and charging infrastructure may not be equipped to provide hundreds of kW at the same time to a convoy of electric lorries. For this reason, companies like Nikola have already collected over 7,000 pre-orders for their fuel cell-powered trucks, which are leased (and not sold), while the company prepares for covering the entire US soil with proprietary hydrogen-refuelling stations. As Tesla abandons its initially ambitious plans on selling thousands of battery-powered semis, this can be a golden opportunity for all those companies willing to embrace hydrogen solutions outside of the passenger car market. Finally, hydrogen might take it to the skies too, thanks to joint efforts in the drone industry in switching away from bulky and slow-to-charge batteries, in favour of small hydrogen tanks that can be refilled in seconds and enable longer range for commercial and military drones. Similar efforts are also underway in the marine vehicle sector, where H2 can meet shortcomings that batteries have failed to address. For this reason, IDTechEx has analysed nine different EV categories on land, sea, and air, and assessed their market potential in the 2019-2029 timeframe in the report Fuel Cell Vehicles 2019-2029. This 530-page technical report contains information on the main R&D efforts being carried out worldwide, existing challenges, and unexplored market opportunities. A multibillion-dollar market by 2029, fuel cells can be a complementary technology in all those EV applications where batteries are too costly, too slow, or just not the right fit.

Australia’s debit network, eftpos, recently announced it is fast-tracking the enablement of eftpos Tap & Pay technology for use on buses, trains and ferries, following new consumer research that shows Australian commuters would prefer to pay for transport with eftpos debit. eftpos Managing Director, Mr Stephen Benton, said that while eftpos had been working on transport for some time, the company had recently formed a dedicated technical and business team to complete the capability rollout to financial institutions across Australia by April 2019, and was already in discussions with a number of State Governments. Mr Benton said the new transport team at eftpos would also focus on rolling out eftpos Tap & Pay to other types of unattended payment devices such as parking metres and vending machines. The move follows the successful rollout of eftpos Tap & Pay capability to around 30 million cards and 900,000 point of sale terminals across Australia over the past four years. “As tap payments are introduced on transport systems across Australia, it is vital for eftpos debit to be included to ensure all Australians have access to the benefits of this technology and can use their own money, rather than credit,” Mr Benton said. “The inclusion of eftpos, in addition to the international credit card schemes, will also help drive competition and better outcomes for State Governments and taxpayers.” Transport is the next natural progression for eftpos Tap & Pay, with a new consumer survey of 1,500 Australians showing that 82% of people would prefer not to use credit for transport payments.

According to the survey, debit is the preferred way to pay for transport with 37% support, while eftpos is the preferred debit brand. Preference for eftpos is particularly high for lower income people, families, over 50s and young people who regularly use public transport. Of those Australians who only hold an eftpos card, around 20% are youth, 42% are over 50, 51% are renters and 34% are unemployed or stay at home. Mr Benton said eftpos Tap & Pay for transport would provide a number of important benefits for budget conscious eftpos cardholders, including not having to preload funds on transport cards, and a seamless interstate transport experience.

“Our approach to mitigate these impacts was to focus on high-risk environmental and community issues while engaging collaboratively with the contractor and client to ensure zero major environmental incident occurred,” Mr Peterson said. “This approach was successful, and the project was delivered with minimal impact to the environment and adjacent stakeholders,” he added. The Barangaroo Ferry Hub, a new $59m transport infrastructure project on the western edge of the central city, is now open to serve the public. It increases Sydney’s ferry capacity, serving thousands of residents, visitors and workers travelling to the Barangaroo commercial and residential precinct.

SNC-Lavalin completes role as independent environmental representative for Sydney’s Barangaroo Ferry Hub

Mobile Media Blasting - Wet & Dry

SNC-Lavalin has successfully completed its role as independent environmental representative for the construction of the Barangaroo Ferry Hub project in Sydney. Richard Peterson, SNC-Lavalin’s Director for Environment and Geosciences in Australia, said: “I’m very pleased to see the Barangaroo Ferry Hub become operational to provide residents and visitors alike with more public transport options, whilst having enabled construction through an environmental conscious approach that protects the worldfamous Sydney Harbour.” Appointed by Transport for NSW in 2016, SNC-Lavalin acted as the independent environmental representative to ensure that the construction contractor complied with project conditions of approval and environmental requirements, whilst ensuring that sensitive environmental practices were followed. The project involves the construction of two new ferry wharves at Barangaroo South, and ancillary landside facilities on Sydney Harbour. Situated adjacent to a range of restaurants and residents, the risk of environmental incidents was high.

Dynapac CP1200 delivers the ideal combination of weight and size for May Asphalt When it comes to choosing the right equipment for the job, size really does matter… especially when it comes to moving equipment from job to job. Transport and logistics can represent a major cost - even on relatively small jobs – and put simply, the larger the equipment, the higher the cost. With that in mind, when it came to selecting a new multiwheeled roller for their equipment fleet, Melbourne-based road and infrastructure specialist May Asphalt Group chose the Dynapac CP1200W. May Asphalt Group Managing Director, Rick May, explained: “Together with our focus on quality and safety, we also place a significant emphasis on sustainability. We’re fully certified to ISO14001 environmental certification, and as such, our goal is to minimise both the carbon footprint and environmental impact of every aspect of our operations.” “Needless to say, that focus on sustainability not only covers the jobs themselves, it also extends to things such as vehicle movements and the impact of transporting equipment between jobs,” he added. “After looking at the available options, we felt that the Dynapac CP1200W would provide us with the ideal solution,” Rick May added. “While it has the weight, speed and manoeuvrability to handle larger overlay jobs, its compact size means it’s much easier to float between jobs – reducing transport costs, heavy vehicle movements and our overall carbon footprint.” The smallest of Dynapac’s series of pneumatic tyre rollers, the CP1200W incorporates many of the features of the larger rollers in a compact, heavy-duty chassis. The CP1200W is ideally suited for jobs of all sizes ranging from small car parks and patch work to large highway works, and can be used for chip-sealing, compacting asphalt for sealing purposes, and to compact base, sub-base and stabilised soil.

10 Highway Engineering Australia | Dec 2018/Jan 2019

Designed with a focus on robust performance and reliability, the Dynapac CP1200W is powered by a Cummins QSF2.8 Stage IIIA /Tier 3 producing an output of 55kW (74hp) @ 2200rpm. As well as helping to optimise fuel efficiency and reduce operating noise, the combination of the QSF2.8 powerplant and Dynapac’s smooth start-stop action help to maximise efficiency, productivity and ease-of-use. Available with either ROPS or full factory air-conditioned cabin, the Dynapac CP1200W also comes standard with a 180-degree rotating and sliding operator’s station, this allows the operator to swivel the control console 90 degrees to the left or right side for maximum comfort and convenience. All switches and controls are clearly visible and within easy reach with the switch cluster following the seat movement, making the unit both easy and comfortable to use. The unit has also been designed for maximum safety, with the operator seat placed on slides, and the ROPS positioned so as not to obstruct the view. The operator can keep an eye on the finest details, while also being able to stay aware of movements close to the machine. With the basic unit weighing in at 5,215kg to 5,570kg (depending on canopy / cab options), the CP1200W has a range of additional ballast options, including water, wet sand or Dynapac’s Flexible Steel ballast system, up to a total weight of 12,100kg. Importantly, the CP1200W has been designed to ensure that the ballast is distributed evenly to provide the same ground pressure on front and rear tyres, regardless of whether water, sand or steel is used. “We’re very happy with the new roller,” Rick May said. “It has provided us with the ideal combination of size and performance, and the weight ratio marries up well with our steel drum roller.” “Importantly, the new CP1200W is not only delivering great results out in the field, it’s also delivering a significant reduction in both transport and logistic costs, and our overall carbon footprint,” he concluded.

Highperformance products for reliable work site traffic control

As anyone who has ever been on a work site will tell you, having effective and reliable traffic control is not only a critical factor in ensuring safety for both workers and road users, it also plays a key role in allowing work to progress. What’s more, for larger projects – where traffic counterflow measures may need to be in place for an extended period – the traffic control devices being used, need to be robust, reliable, and capable of delivering continued performance 24/7.

12 Highway Engineering Australia | Dec 2018/Jan 2019


ith that in mind, traffic control, linemarking and safety equipment specialists A1 Roadlines, has developed its portable traffic control and signal systems with a focus on maximum visibility, ease of use and robust reliability. Janine Bartholomew, Manager, A1 Roadlines, explained: “When it comes to portable traffic lights or flashing direction arrows, one of the key factors in improving worksite safety and worker OH&S is to ensure that road users can see them clearly – in all ambient light and weather conditions.” “Whether it’s a large worksite where there’s a lot going on and a lot of distractions, or small remote site in the middle of nowhere, the clearer and more visible the traffic control, the more warning the driver has – giving them maximum opportunity to respond and drive according.”

“Once they’re at the worksite, the units can be set up and operational within a matter of minutes...”

“The next requirement is that the units need to be easy to set up and use,” Janine added. “No one wants to spend a large portion of their day trying to get the traffic control up and running, and that’s why we’ve placed an emphasis on designing our lights and arrow boards with a focus on fast, easy and highly intuitive setup and operation.” “Once they’re at the worksite, the units can be set up and operational within a matter of minutes, allowing the crews to focus on the job at hand,” she said.

CS-400 SOLAR PORTABLE TRAFFIC SIGNAL SYSTEM The latest addition to A1 Roadlines’ range, the CS-400 Solar Portable Traffic Signal System brings to life a new generation of portable traffic light controllers. Whilst it purposely retains many of the features of its predecessor (CS-200) for familiarity and ease of use, the CS-400 also delivers an impressive list of new features that are 25 years in the making. The CS-400 system is comprised of two CS-400 controllers mounted in a trailer unit that is capable of being split, with each unit being positioned separately on the work site. The dual-trailer system design allows the trailers to be connected together so they can be safely and legally towed as one unit.

CAN WE REDUCE THE ROAD TOLL BY MAKING OUR ROADS MORE SKID RESISTANT? Australia’s national transport research organisation ARRB has introduced new guidelines to assist local councils and road asset managers in properly using High Friction Surface Treatments. High Friction Surface Treatments are compounds designed to make roads more skid resistant. Used appropriately, they can help stop vehicles from skidding on or off roads, and increase a vehicle’s ability to brake more effectively at critical times. ARRB says known accident blackspots, approaches to intersections and pedestrian crossings, and tricky-to-negotiate corners can all benefit from proper use of High Friction Surface Treatments. Utilising polymer resin, the High Friction Surface Treatment can be applied to existing roads that are in good condition. “These guidelines will enable those responsible for maintaining road networks to make informed decisions, and to select the right treatment for the right spots, with the aim of improving road safety,” says Steve Patrick, ARRB Senior Professional Leader, Future Transport Infrastructure, who compiled the guide. With 50% of urban crashes occurring at intersections, and a high percentage of rural crashes involving cars leaving the road, discovering roads where skid resistance should be improved is vital.

“ARRB’s Intelligent Safe Surface Assessment Vehicle (iSSAVe) is a unique tool that can be used to determine where High Friction Surface Treatments may be beneficial,” said Richard Wix, ARRB Principal Professional, Strategic Enablers Group. “The iSSAVe measures skid resistance at the same time it collects asset imagery and other safety related parameters such as road geometry, texture, roughness and rutting. “Local government authorities can ask ARRB to measure the condition of their road network with iSSAVe, and we can determine a prioritised list of sites which could benefit from High Friction Surface Treatments.” You can download ARRB’s High Friction Surface Guide to Good Practice at ARRB’s website at the link: www.arrb.com.au/hfst-guide To discuss with ARRB how the National Transport Research Organisation can help with skid resistance measurement, contact Richard Wix at: richard.wix@arrb.com.au

TITAN HELPS CUSTOMERS TO STAY ‘ON TRACK’ As part of the world’s largest and most experienced manufacturers of undercarriage components for tracked equipment, and the only company in Australia to manufacture and supply both tyres, wheels and undercarriage, Titan Australia has been helping its customers to keep their equipment ‘on track’ for many years. From heavy construction and mining, through to drill rigs and infrastructure projects, Titan is a trusted name across a wide range of industry sectors, and has gained an enviable reputation for both the quality of their components and the speed of their service. “We understand that when it comes to heavy, tracked equipment, downtime can be extremely expensive – regardless of the industry,” Titan Australia Chief Operating Officer, Adam Oakenful, said. “What’s more, with the larger equipment, it also tends to play a critical ‘frontline’ role for many projects, meaning that if it stops working, the whole project or site stops working.” “With that in mind, from the outset, we established our undercarriage business with a focus on minimising turnaround times to minimise downtime – regardless of the customer’s location, or whether it’s for new tracks, individual components or repairs and refurbishments,” he said. Importantly, this focus on quality customer service is further bolstered by Titan’s focus on only supplying the highest quality products and components.

Renowned across the globe, Titan’s ITM brand is considered ‘the undercarriage of choice’ for many operators across a wide range of industry sectors. Manufactured at their facilities across Europe, Titan supplies a full range of high quality steel undercarriage components, from full track groups through to track components - Rollers, Idlers and Sprockets for equipment ranging in size from 13-tonne up to 550-tonne. “When it comes to parts and equipment, quality and longevity equal value,” Adam Oakenful, said. “Our clients need to be sure that our components can stand up to even the harshest operating conditions. After all, a lot of this equipment works in some of the harshest conditions on the planet!” “That’s one of the main benefits of having our own brand,” he added. “Because we control all aspects of the manufacturing process from start to finish – including quality control – we can be sure that we’re providing our customers with the highest possible quality components. They, in turn, also have the peace-of-mind in knowing that their undercarriage components are not only fit for purpose, they’re made to last.” This focus on working with customers to help minimise downtime and operating costs to maximise value is also evidenced by Titan’s CTS inspection service and undercarriage refurbishment works. Forming a significant part of the company’s business, Titan provides a full repair and refurbishment service for all

manner of tracks. Titan’s free on-site CTS inspection service enables clients to ascertain the current condition of their tracks, assess performance and wear, and determine if any components require refurbishment or replacement. In many cases, refurbishing tracks, or performing maintenance such as a ‘pin and bush’ turn, can help to extend the life of the tracks, and can be carried out for significantly less than the cost of new replacement parts - providing substantial savings for customers, without any compromise in quality or performance when compared to a new replacement part.

QUT civil engineering professor and ANSHM founding president, Professor Tommy Chan.

Sophisticated sensors keep bridges, dams and buildings safe The Story Bridge is 78 years old, the Sydney Harbour Bridge is hitting 95. Australian bridges are designed for a life span of 100 years. “The designers of these bridges allowed for the growth of traffic and load consideration, so safety factors for material strength were built into bridges like the Story and Sydney Harbour bridges,” QUT civil engineering Professor Tommy Chan. “The Sydney Harbour Bridge is being fitted with 2400 sensors to monitor its structural health. “While this bridge has had regular maintenance, strengthening and tests to ensure it is safe, the use of sensors to detect damage caused by traffic, wind, temperature, vibration and extreme events add an extra level of safety by alerting asset owners to timely maintenance. “Some defects or damage may not be detected using visual inspection only and a sensor system can let us know whether the structure is performing as expected.”

20 Highway Engineering Australia | Dec 2018/Jan 2019

Professor Chan said the latest Structural Health Monitoring (SHM) technologies provided 24/7 monitoring of large structures and alerted asset owners when some part of the structure needed attention. “SHM technologies add extra safety measures beyond the traditional method of routine scheduled, visual checks,” he said. “Using SHM we can determine when structures need a retrofit, rehabilitation and strengthening. This is why the Australian Network of Structural Health Monitoring (ANSHM) is promoting SHM systems to be implemented to existing structures and built into new structures.” Professor Chan drafted the SHM section in the latest version of AS5100 (Australian Bridge Design Standard). “SHM uses various sensing devices and ancillary systems to monitor the in-situ behaviour of a structure to assess and evaluate its condition,” Professor Chan said. “We have developed extra SHM technologies to detect, locate, and assess the

severity of damage and deterioration in not only bridges and but also buildings, dams and towers. “Spending 1 to 5 per cent of the construction cost of a structure on installing SHM during the build, can provide minimum to comprehensive levels to monitor structures for timely maintenance. “It is an effective way to detect structural problems and also predict the remaining life of structures.” “Vibration-based damage detection uses accelerometers to identify the dynamic characteristics of bridges, such as frequencies and mode shapes,” he said. “On suspension bridges we use anemometers to monitor wind speed and direction because there is a lot of aerodynamic interaction between wind, structure and traffic. “We measure the traffic load and the bridge’s responses to know whether it is performing according to the design assumptions - the system gives an alert if it is not performing properly.


Specialist sensors are used to monitor the structural health of bridges.

capacity of existing prestressed concrete bridges.” Professor Chan and Professor David Thambiratnam, together with other SHM experts in Australia established the Australian

Network of Structural Health Monitoring (ANSHM) in 2009 at QUT to promote SHM technologies and raise general community awareness on its need and its value. Professor Chan remains ANSHM founding president.

“With a concrete bridge, for example, we need to know the temperature inside the concrete as well as the outside in order to estimate any developing thermal stresses because if a structure needs to expand and it is stopped from expanding it adds stresses to the structure.” Professor Chan said bridges deteriorated at different rates depending upon bridge design and materials used. “This means different SHM systems for different levels of monitoring need to be considered and implemented,” he said. “The latest SHM technologies could help to determine what needs to be replaced, retrofitted, or rehabilitated.” Professor Chan said his ARC-funded research project on the development of prestressed concrete bridges using moving force identification would have been applicable in testing the Morandi Bridge in Genoa that recently collapsed. “This bridge was the first modern prestressed, concrete cable-stayed bridge. The project developed three different methods to identify prestress force of existing bridges which will be useful to evaluate the loading

One in five local timber bridges in poor state Ahead of an upcoming federal election, local councils have joined the Australian Local Government Association (ALGA) to call for permanency of the Federal Bridges Renewal Program to help fix the roughly one in five local timber bridges that are in poor condition. The findings came out of the 2018 National State of the Assets: Roads and Community Infrastructure Report, which was launched at the recent National Local Roads and Transport Congress in Alice Springs. ALGA President, Mayor David O’Loughlin, said that despite increased investment to renew bridges and the continued effort of councils to extend the life of their ageing assets, the backlog of bridges in poor condition remained largely unchanged. “Councils are doing their best to bring these bridges up to a reasonable condition but this report shows that the scale of the problem is beyond the current resources and revenue streams available to councils.

“The Bridges Renewal Program has proved to be a very successful and important partnership between the Commonwealth and councils to improve road safety and freight productivity; more than 205 local bridges have been fixed using around $120 million of Commonwealth funding. “Councils are keen to continue this partnership to deliver this important work and are calling for the program to be made permanent.” Along with the uncertainty of the Bridges Renewal Program, further pressure has been placed on council budgets with the core Commonwealth funding to local government, Financial Assistance Grants (FAGs), being in steady decline over the past 20 years, falling from 1% of Commonwealth Taxation Revenue in 1996 to just 0.55% today. “The fall in this funding has been swept under the rug for too long and the impact has been most acutely felt in regional and remote councils throughout Australia.

“The Bridges Renewal program helps tackle the backlog in fixing bridges, but a fairer share of Commonwealth taxes is vital to restoring sustainable levels of funding in the longer term, particularly for our regional and remote communities. “That is why we are also calling for a restoration of the FAGs funding levels back to at least 1% of CTR to ensure our councils are adequately resourced to provide, maintain and renew the infrastructure and services our communities deserve.” More than 400 councils across Australia provided data for the 2018 State of the Assets report.

Viaduct Over River Almonte in Spain Awarded Highest Honour in ACI’s Excellence in Concrete Construction Awards The highest honour in the recent American Concrete Institute (ACI) 2018 Excellence in Concrete Construction Awards was presented to Viaduct Over River Almonte in Garrovillas de Alconétar, Cáceres, Extremadura, Spain. This award is given annually to one project that demonstrates excellence in concrete innovation and technology and stands out above all other entries. A new high-speed rail line is under construction between Madrid and the Extremadura, a western Spanish region bordering Portugal. The line will cross over the River Almonte on a 996m long viaduct—a concrete arch bridge with a main span of 384m. Designed to carry 350 km/h rail traffic, the viaduct had to meet rigorous dynamic, serviceability, and safety criteria; and it required complex, staged calculations based on nonlinear material and nonlinear geometry behaviours. Nevertheless, it is aerodynamic and slender, largely due to key design features, including a four-legged arch configuration; 80 MPa highperformance concrete; an efficient erection method, with temporary towers and stays; and an innovative monitoring system.

22 Highway Engineering Australia | Dec 2018/Jan 2019

The viaduct’s 384 m main span makes it the largest railway bridge in Spain and the world’s largest concrete arch bridge for high-speed rail service. Its design combines structural efficiency, out-of-plane stability, improved response against cross wind effects, and aesthetics. The design is also environmentally friendly, as the bridge comprises durable materials, has been designed for expedient maintenance, and will include a bespoke barrier that will force birds to soar upward and above the overhead mast line. The bridge arch comprises high-performance, selfconsolidating concrete. The complex erection procedure required the development of singular construction devices. The bridge was constructed using a ground-breaking instrumentation and monitoring system that provides information regarding the behaviour of the structure during construction and service. The ACI Excellence in Concrete Construction Awards were created to honour the visions of the most creative projects in the concrete industry, while providing a platform to recognize concrete innovation, technology, and excellence across the globe. To be eligible for participation in the Excellence Awards,

projects needed to be winners at a local ACI Chapter level and submitted by that Chapter or chosen by one of ACI’s International Partners. An independent panel of esteemed industry professionals judged projects and selected winners based on architectural and engineering merit, creativity, innovative construction techniques or solutions, innovative use of materials, ingenuity, sustainability, resilience, and functionality. Entries for the 2019 Excellence in Concrete Construction Awards are being accepted now through April 2, 2019. For further information, please visit: www.ACIExcellence.org


New York’s new Governor Mario M. Cuomo Bridge opened to traffic The westbound bridge will remain in a temporary configuration while crews complete the bridge’s shared-use path connecting Westchester (New York) and Rockland (New York) counties for pedestrians and cyclists. The New York State Thruway Authority, in partnership with the Fluor-led joint venture of Tappan Zee Constructors, LLC – comprised of American Bridge Company, Granite Construction Northeast, Inc. and Taylor Bros.,

The final span of the new Governor Mario M. Cuomo Bridge, which replaced the Tappan Zee Bridge in New York, opened to drivers recently, with all four lanes of eastbound traffic shifting to the new second span of the iconic cable-stayed bridge. The eastbound span will consist of four general purpose traffic lanes, two emergency shoulders, space for a dedicated bus lane and an advanced traffic monitoring system.















Inc. – replaced the old bridge with a new 3.1-mile state-of-the-art, twin-span, cablestayed bridge crossing the Hudson River between Westchester and Rockland counties. The cable-stayed main span is supported by eight 419-foot towers, which stand at fivedegree angles and feature a sleek, chamfered design. The iconic towers support 192 stay cables, which are made up of roughly 4,900 miles of steel strands. “Fluor is honoured to have been the lead design-builder for this project,” said Terence Easton, president of Fluor’s infrastructure business line. “We are proud of the team that delivered the Governor Mario M. Cuomo Bridge to New York. This is a landmark project that provides a vital link to the region and improves daily commerce.” The Governor Mario M. Cuomo Bridge is one of the largest single design-build contracts for a transportation project in the United States and is the largest bridge project in New York state history.

Three Products That Could Help Your Business Today Looking for a way to improve and add life to your existing asphaltmixing plant? Ammann has several solutions in the form of Ammapax and Amdurit®. In addition, asphalt producers who want to utilise more recycled asphalt (RAP) also can give their business a boost through a new machine that shreds, separates and screens asphalt – transforming it from discarded material to valuable aggregate.

Ammapax: A Cost-Effective Update Sound restrictions for asphalt-mixing plants are constantly tightened. When new standards are authorised, plant owners have no choice but to comply. But, thanks to a recent innovation, there is an easy option for meeting the everchanging regulations. Ammapax® from Ammann is a quick and cost-effective solution. With this sound suppression system, there is no need to buy a new asphalt-mixing plant or even pay for an expensive retrofit that could take weeks to install and halts production. Ammapax fits over the plant’s flue and is simple to install – only four fastening screws are required. The problem is solved quickly, with no change in production. But is Ammapax effective? Absolutely. Depending on the Ammapax model, it reduces noise levels by 10 dB, 15 dB or even 20 dB. That includes minimising long-wave frequencies that are increasingly targeted by regulators.

The beginnings of Amdurit® go back to 2009, when the increased use of recycled material had begun to take a serious toll on plant components. Wear-proof steel was utilised, but even that wasn’t enough. To create Amdurit, product developers started with existing protection, which they further strengthened by changing the material compositions to yield a higher degree of hardness. The production of Amdurit involves other steps, too. A steel plate is mounted and welded. Heat is applied to bend the plate, which subsequently passes through a roller to be restraightened. The surface then is smoothed to prevent caking, and the plate is sized by a plasma cutting machine. The result: a standard Amdurit plate, providing up to three times the service life of wear-resistant steel.

RSS 120-M Shredder: Making RAP Easier to Work With

Amdurit®: An Innovation that Lasts The RSS 120-M Shredder, Iron Separator and Screen is a mobile machine that prepares RAP for use in an asphalt-mixing plant. It is unique because of its ability to shred, separate and screen. That’s just the start. The RSS 120-M’s patented crushing system sets it even further apart by maintaining desired grain sizes when crushing. Consistent grain sizes means there are fewer fine materials – and fines are what make RAP sticky and difficult to work with. Therefore, minimising those fines makes the entire process less frustrating, more efficient – and more profitable.

The AutoSet Plus Paving Programs function assisted the paving team on the motorway job site near Potsdam.

AutoSet Plus from VÖGELE Hi-tech paver ‘thinks for itself’

On a recent project to widen Germany’s Berlin Ring Road from six to eight lanes, AutoSet Plus, the automatic functions of the VÖGELE pavers, made it a lot easier for the paving team from Johann Bunte Bauunternehmung GmbH & Co KG to move between the many small job-site sections. Paving processes can be automated with AutoSet Plus, so that quality achieved in the past can be reproduced at the push of a button. The function is integrated in the paver operator's ErgoPlus 3 console on the VÖGELE paver and is particularly suitable for construction projects with several sections. These benefits were showcased by the recent project on the Berlin Ring Road, along one of the most heavily used stretches of the A10 between the Potsdam and Nuthetal junctions. Traffic on the 9km-long section has been tipped to increase from 90,000 to 126,000 vehicles per day by 2025. In response to this, the A10 had to be expanded from six to eight lanes in this area by 2020. To this end, the three existing westbound lanes first had to be completely removed. Next, four new lanes were to be built from scratch. The same procedure would then be applied for the eastbound carriageway. However, widening the road to a width of 18.5m in each direction was fraught with challenges for the contractor, Johann Bunte Bauunternehmung GmbH & Co. KG. One of the major issues was that the existing bridges along this section were not configured for this width and had to be replaced and widened. That meant that the paving team frequently had to move

26 Highway Engineering Australia | Dec 2018/Jan 2019

from one strip to the next and between the sections while also paving a variety of mixes – sometimes within the same work shift.

Paving parameters and settings saved at the push of a button “Normally we have to set all the paving parameters again every time we reposition the paver,” explains Henry Moser, Paving Foreman at Johann Bunte Bauunternehmung GmbH & Co. KG. “The same applies for every new layer if a different mix is to be paved with a different thickness and paving speed.” “In a construction project such as the widening of the A10, the settings for the 2 VÖGELE SUPER 1900-3i and SUPER 2100-3i pavers would have to be re-entered again and again. And when there’s time pressure as well, it goes without saying that mistakes can arise,” Moser adds. “That’s why we made use of the assistance provided by AutoSet Plus on the job site.” AutoSet Plus is integrated in the paver operator's ErgoPlus 3 console and offers two basic functions. First, there is the Repositioning and Transport function, which brings the paver into transport position while saving any paving-related settings. Second, AutoSet Plus features the Paving Programs

function - this enables users to save all paving parameters such as type of mix, pave width, type of layer and machine settings which are of relevance on the job site and then retrieve them as required. Pictured below: Saved settings can be retrieved from the AutoSet Plus program memory and activated at any time.


Consistently high quality The second function lent key support to the paving team on the Berlin job site, enabling them to first paved one strip, followed by two more parallel strips. The critical factor in the process was that each mix for the various asphalt layers had to be paved with identical parameters. To achieve this, both paver operators saved the settings after each layer (base, binder and surface courses) as a paving program whenever this layer was laid for the first time. This was quick and easy to do, because most of the settings can be taken over automatically by AutoSet Plus. After laying the asphalt pavement on one of the sections, the paving team transported the two VÖGELE Highway Class pavers to the next section – and the operators were able to continue working with identical settings at the press of a button. “That enables us to ensure that every asphalt layer is laid and pre-compacted in exactly the same way on each section,” adds Jürgen Schimang, Asphalt Coordinator at Johann Bunte Bauunternehmung. “AutoSet Plus gives the paving team a high degree of confidence, because there is one less potential cause of errors. It helps us by providing increased process reliability; and benefits the client, because they can be sure that every metre of every layer is paved identically.”

3D control with Navitronic Plus temperature control with RoadScan The use of AutoSet Plus was not the only innovative aspect of the paving work along the Berlin Ring Road. To ensure the pavement was true to line and level exactly

Top: The 3D machine control system Navitronic Plus takes care of the steering, while controlling the grade and slope as well as the screed’s position. Above: AutoSet Plus allows each mix for the various asphalt layers to be paved with identical parameters.

as specified in the planning data, the SUPER 2100-3i was also equipped with Navitronic Plus from VÖGELE. The 3D control system takes over the grade and slope control – automatic control of the grade and crossfall – while also controlling the screed’s position. But that’s not all… Navitronic Plus also handles the steering of VÖGELE tracked pavers – a benefit that only VÖGELE offers their customers. To provide a virtual

reference, an mmGPS system from TopCon (3D zone laser and GPS) was used on the Berlin Ring Road. This automatically ensured maximum precision in truth to line and level. Johann Bunte Bauunternehmung additionally used the VÖGELE temperature-measurement system RoadScan to document the paving results. Visit www.voegele.info for further information.

TMA FACT SHEET What you need to know about TL-3, MASH, Standards and Compliance BEWARE OF ‘FAKE NEWS’ Recent amendments to the Australian / New Zealand Standard AS/NZS 3845.2:2017 ‘Road safety barrier systems and devices – Part 2: Road safety devices’, as well as the planned move towards MASH (Manual for Assessing Safety Hardware) testing in place of NCHRP350 testing, has seen increased interest in the testing and certification status of Truck Mounted Attenuators (TMA’s) currently in use in Australia. Unfortunately, this has also led to confusion amongst some equipment owners as to what equipment is compliant and, perhaps more importantly, what the


status of their equipment will be after Australia moves to MASH as the testing standard – a situation which is no doubt being inflamed by the inaccurate information and spurious claims that have surfaced over the past 12 months. With that in mind, the following fact sheet has been developed to provide key information as to the current status of the ‘Transition to MASH Guidelines’ and, more importantly, to provide you with the information you need to ensure that your TMA complies with all of the relevant regulations.

On April 23 2018 the Austroads Safety Barrier Assessment Panel (ASBAP) announced that ‘…effective immediately, all submissions received by the Panel must be in accordance with AASHTO's MASH guidelines or an equivalence rating to MASH in accordance with AS/NZS3845 Parts 1 and 2’ rather than the previous NCHRP350 guidelines.

While there is a formal agreement on the transition to MASH testing from NCHRP350 testing, there have been NO FORMAL ANNOUNCEMENTS as to the future suitability and compliance of equipment tested and certified to NCHRP350.

The move towards MASH testing and certification is a complex process that will take some time to implement. The Panel is transitioning the current suite of accepted road safety barrier systems and devices within the Australasian market to MASH guidelines over an extended timeframe, with Part 2 Products (which includes TMA’s) to be completed by 31 December 2020.


This DOES NOT by any definition mean that non-MASH tested equipment is suddenly obsolete or can no longer be used. While the Australian/New Zealand Standard AS/NZS 3845.2:2017 ‘Road safety barrier systems and devices – Part 2: Road safety devices’ stipulates MASH as the basis of testing procedures for TMAs, it DOES NOT render devices that have been previously approved as tested under NCHRP350 guidelines obsolete or unusable – to suggest otherwise is simply NOT TRUE. The move towards MASH testing and certification is a complex process that will take some time to implement. “In the past, devices tested to NCHRP TL3 have been considered acceptable for use on Australian and New Zealand roads. This can still be the case, although in the future MASH tested devices are likely to be preferred.” Extract from AS/NZS 3845.2:2017 – Appendix D - 3.4 Testing to other standards

There is certainly NO CUT-OFF DATE for equipment that has been certified under the NCHRP350 testing while it is operational. IMPORTANTLY, the updated Standard AS/NZS 3845.2:2017 specifically refers to and DOES NOT preclude TMAs that are tested and certified to NCHRP350 TL3 requirements. TMAs that are tested and certified to NCHRP350 and/ or MASH specifications are listed with Barrier Terminals and Crash Cushions on the U.S. Department of Transport Federal Highway Administration website at: https://safety.fhwa.dot.gov/roadway_dept/countermeasures/ reduce_crash_severity/listing.cfm?code=cushions


TMAs must still be approved for use by State jurisdictions. Even if a TMA is recommended for acceptance at an Austroads level by ASBAP, it must still be approved for use by the relevant State jurisdiction.


The approval process is on-going and the lists are growing

The transition to MASH guidelines is a lengthy and on-going process. Lists of ‘Austroads Approved Products’ are currently a Work in Progress, and will continue to grow as the process progresses. The fact that a product does not currently appear on a jurisdiction’s list, or if it is not currently listed as MASH approved, DOES NOT MEAN that it has not been successfully tested and certified to MASH guidelines, or that it is not acceptable for use in that jurisdiction. It may simply have not yet been assessed by ASBAP. Important Notes: 1. ASBAP have stated that after 31 December 2020, AS/NZS 3845.2:2017 type products should be assessed under MASH protocols.

2. Prior to 31 December 2020, crashworthiness may be demonstrated via crash testing to other protocols (for example, NCHRP350). 3. Operators are advised that over time, the list below will be populated as more products are submitted to ASBAP and assessed by ASBAP. Operators are recommended to be cognisant that the ASBAP assessment process may take considerable time, and they should continue with ‘business as usual’ arrangements. 4. Products not listed below may still be operationally acceptable to TMR under existing or future arrangements. 5. It is NOT the intention of the list below to imply that other products are not acceptable for use by TMR and cannot be used operationally by TMR.

Boral and Road Safety Education Announce Major Sponsorship to Make Australia’s Roads Safer Boral Limited and Road Safety Education Limited (RSE) have announced they are joining forces to help make Australia’s roads safer, signing a three-year sponsorship agreement that will help provide driver education to over 40,000 senior high school students every year. The community partnership will see Boral become a major sponsor for RSE’s flagship program RYDA, which provides young drivers with life-saving knowledge and skills. Now in its 17th year, the national program involves senior high school students and focuses on cognition development, helping students develop and practise personalised strategies and life skills which will help them respond positively to challenges on the road, both as drivers and highly influential passengers. The Divisional Chief Executive of Boral Australia, Joe Goss, said the partnership program provided an invaluable opportunity for Boral - an industry leader when it comes to safety and an operator of over 2,500 heavy vehicles in Australia - to work with RSE to help improve road safety. “We are particularly excited about joining forces with RSE, whose programs are recognised as world class and have provided vital driver education skills to more than 500,000 students in high schools across the country over the past 17 years,” said Mr Goss. “Boral takes safety extremely seriously, with a commitment to zero harm across our operations, including our drivers on public roads. “We have a strong focus on safety and training for our drivers, but 93 percent of fatal accidents involving heavy vehicles are not caused by the driver of the heavy vehicle. So there is an obvious gap, which this new road safety partnership will attempt to address. “We are looking forward to working with RSE and sharing our knowledge to help develop additional education material and awareness training for young drivers when it comes to sharing the road with heavy vehicles. This means improving road safety for young people, heavy vehicle drivers and the community more broadly.” The CEO & Managing Director of RSE, Terry Birss, said the organisation was delighted to be partnering with Boral and was deeply appreciative of Boral’s significant commitment to the RYDA program. “Boral is supporting our mission of providing young Australian road users with learning that supports the development of a road safety culture across the generations,” Mr Birss said.

“Road safety is a shared responsibility and making our roads safer requires the support of organisations such as Boral. “Youth road trauma is a community tragedy that needs a whole of community response. Road trauma levels have declined over the years, however, the annual economic cost of road crashes in Australia is estimated at $27 billion, and the social impacts are devastating. “By joining the RYDA family, Boral and RSE will work towards their goal of achieving zero harm and educating all novice drivers and their passengers on road safety.” Fatal crashes on Australian roads involving heavy vehicles decreased by an average of 2.0 per cent per year over the three years to June 2018. Boral and RSE believe that the increased heavy vehicle awareness and knowledge within the community achieved through this partnership will help deliver even bigger improvements.

About Road Safety Education Road Safety Education Limited (RSE) is a not for profit organisation committed to reducing trauma, delivering highly effective, evidencebased road safety education programs to young people in senior high school.

Ideagen’s software helps RATP Dev USA ‘reduce vehicle accidents by 19%’ Ideagen, the UK-based, global software firm, recently announced it has helped a major transportation company reduce vehicle accidents by 19%. RATP Dev USA, a wholly owned subsidiary of RATP Group which operates and maintains urban intercity transportation systems in 14 countries, launched its drive2zero™ Safety Management System (SMS) last year and adopted Ideagen’s software. Coruson, Ideagen’s cloud-based system for enterprise safety, quality, reporting and incident management, is used by RATP Dev USA to directly manage safety, risk and operational performance across all bus, paratransit and rail services. Mike Anderson, VP of Safety and Security for RATP Dev USA, commented: “We started implementing SMS in our subsidiaries back in December 2017 and, to date, we’ve implemented SMS in eight out of around 35 - so we still have a lot of work to do.”

“But our initial results are very promising – we’ve seen an overall reduction year-to-date of 19% in vehicle accidents alone,” Mr Anderson added. As part of the same framework, SmartDrive Systems, a leader in video-based safety and transportation intelligence, provide RATP Dev USA’s fleets, drivers and management with driving performance insight and analysis, helping save fuel, expenses and lives. “drive2zero is our internally developed safety solution,” explains Patrick Manley, Director of Safety for RATP Dev USA. “We worked and partnered with Ideagen and SmartDrive to help develop some of the electronic components of the drive2zero SMS.” “Where in the past we have seen companies report positive results in 9 to 12 months, we’re now seeing results in 6 to 7 months. That’s due to an increase in hazard reports as we now have people telling us where risk is in our organisation and a comprehensive way of managing that risk,” Mr Manley added. RATP Dev USA transports more than 78 million passengers across the United States through various transportation services such as bus, urban or intercity rail lines (streetcar), and shuttle services. The drive2zero framework has four components – Safety Policy, Risk Management, Safety Assurance and Safety Promotion. Its aim is to continuously improve transit operations and support RATP Dev USA’s commitment to an unparalleled safety record for customers and employees. Gordon McKeown, Head of Product at Ideagen, said: “This is a fantastic achievement for the team at RATP Dev USA.” “We are absolutely delighted that our Coruson software has played such a crucial part in helping to reduce vehicle accidents across eight RATP Dev USA subsidiaries and we are confident of seeing even more success across the wider network as the project progresses,” Mr McKeown said. Meanwhile across the US, the Public Transportation Agency Safety Plan (PTASP) Final Rule requires operators of public transportation systems to develop safety plans that include processes and procedures necessary for implementing safety management systems. The PTASP rule takes effect from July 2019 and by the following year operators must certify they have a safety plan in place that meets the requirements of the rule. Mike Anderson commented: “Any of our subsidiaries or locations that adopt drive2zero will now automatically meet the requirements of the PTASP rule that will be due in July 2020.” For further information, please visit: www.ideagen.com

Driver engagement and education key to cyclist safety Leading cycling groups including We Ride Australia, the Amy Gillett Foundation and Bicycle NSW have warned that concerted and urgent action is required to address the alarming increase in serious injuries and deaths of cyclists over the last nine years. This includes life-saving education and enforcement of minimum passing distance laws now in place or pledged in all states and territories across Australia, with the exception of Victoria. The benefits and opportunities of driver education campaigns for improving road safety for cyclists has been highlighted in a video interview with the UK’s West Midlands Police about their minimum passing distance enforcement campaign, which was accompanied by a 20% reduction in deaths and serious injuries. Presented to a meeting of senior police from across Australia as part of the 2018 Australasian Road Safety Conference by We Ride Australia, the Amy Gillett Foundation and Bicycle NSW, the discussion continues many state-based conversations that Australian bicycle groups believe will lead to safer roads for all road users. The West Midlands campaign, which has now been adopted by over half of all UK County Police forces, uses a combination of education and enforcement to create safer environments for all road users. The need for such a campaign in Australia is stark, with a worsening road safety record that has seen a doubling of major trauma rates for bicycle riders over the last nine years[i]. In addition, the 2018 report of the Inquiry into the National Road Safety Strategy[ii] raised serious concerns for the safety of bicycle riders (and pedestrians) on Australian roads and made twelve recommendations to induce a ‘step-change’ that, if implemented, will transform road safety performance[iii]. With close to 4 million Australians regularly choosing to ride a bicycle[iv], Australia’s cycling groups are calling for greater investment in education and enforcement of safe passing distance of bicycle riders. We Ride Australia’s Stephen Hodge said “…the co-author of the Government’s recent Inquiry into the National Road Safety Strategy said a ‘crisis of complacency’ and lack of leadership is preventing progress on reducing our road toll[v]. “The video organised by We Ride Australia is a great example of a highly effective education and enforcement program and we hope more can be done to conduct similar campaigns here,” Hodge said. Amy Gillett Foundation CEO, Phoebe Dunn said “…combined education and enforcement can be highly effective in increasing safety for all road users and cyclists in particular.” “We are pleased to be discussing a range of issues around cycling safety with police nationally, including enforcement and education of

minimum passing distance with senior representatives of NSW Police, the NSW Centre for Road Safety and Bicycle NSW,” Ms Dunn said. Bicycle NSW General Manager for Public Affairs, Bastien Wallace, noted the commitment of the senior Police in charge of Roads Policing nationally to be briefed on cycling road safety issues. “We welcomed the chance to brief senior Police officers from every state and territory on our initiatives to address road safety issues for bicycle riders, which we did with We Ride Australia and the Amy Gillett Foundation,” she said.

Call To Action Australian cycling organisations have joined in a call to all states to conduct enforcement campaigns with the primary goal of education and raising awareness of the importance of leaving a safe distance when passing bicycle riders, supported by a visible demonstration by Police of the legitimacy of bicycle riders on roads. Bicycle Queensland CEO, Anne Savage, spoke very highly of work currently underway with Queensland Police. “We’re looking at a comprehensive package of measures to assist both bicycle riders and Police improve the enforcement of safe passing laws in Queensland,” she said. Pedal Power ACT CEO, Ian Ross, said “…here in the ACT we are discussing a campaign with Police based on improved awareness and education on safe passing distance and we have received funding to buy the mats used by UK Police in their enforcement and education campaigns.” Bicycle Network CEO, Craig Richards, said “…it’s been wonderful to work with Tasmania Police to develop guidelines for their members and riders. If a person driving a vehicle passes a person on a bike too closely and it’s not seen by the police, it’s great for riders to know their concerns will be heard.” Western Australia’s WestCycle CEO, Matt Fulton, says “…if we are truly committed to the Towards Zero strategy we must find initiatives that address vulnerable road users and we look forward to continued dialogue with the WA Police, Road Safety Commission and Minister of Police and Road Safety Hon Michelle Roberts MLA, on measures that will make a tangible difference to the community.” Cycling Australia CEO, Steve Drake, said “…we want not only our future cycling champions and Olympians to be safe when they are out riding their bikes on our roads, but every Australian who loves to ride their bike.” [i] Beck, B et al, Road safety: serious injuries remain a major unsolved problem.

Better labelling on child car restraints could increase correct usage by up to 27% In a study released at the recent Safety 2018 World Conference in Bangkok, Thailand, Associate Professor Julie Brown from Neuroscience Research Australia (NeuRA) and Senior Lecturer in the School of Medical Science at UNSW, revealed research statistics that show improved design of child restraint instructional materials could increase correct use by up to 27 per cent, saving lives and preventing injuries. Associate Professor Julie Brown revealed that nearly half of Australian parents using restraints are using them incorrectly, increasing the risk of serious injury to children by up to three times. “Research undertaken at NeuRA identified a critical relationship between comprehension of instructional materials and errors in use,” Associate Professor Brown said. In a survey of 400 Australian parents, 90 per cent reported that they had read the instructions supplied with the restraints, yet high rates of incorrect use continue.

“This suggested instructional materials in their current form may not be effective in communicating how to use restraints correctly, and that we may need to take a new approach to how instructional materials are regulated in product standards,” she said. As part of the study, researchers at NeuRA looked at the range of instructional materials provided by manufacturers of restraints, citing these as a leading cause of errors in use. Following their review, Associate Professor Brown and her team developed a new set of prototype instructional materials for correctly using child restraints. The instructions differ from other instructions because they were designed with a user-driven approach and were tested and refined until at least 80 per cent of study participants achieved correct comprehension and proper use. “Instead of a group of experts sitting around a table developing user guidelines, we asked parents to work with us to develop and drive new instructions, and to then road test them as part of our ongoing research to review and deliver correct comprehension and proper use of installation guidelines,” Associate Professor Brown added. “We are trying to ensure information supplied with child restraints is comprehensible, to ultimately ensure they are installed correctly and do what they are designed to do.”

The new instructional materials developed in the study consisted of an A3-size instruction sheet, a set of four swing tags fixed to the restraint and an online video that demonstrates the overall instruction and usage process with extra video content that demonstrates specific key tasks. The videos are accessible via QR codes fixed to the A3 instruction sheet and the swing tags. Using the new consumer-driven instructional materials 27 per cent more people attained correct use, and comprehension was 42 per cent higher. NeuRA CEO Professor Peter Schofield said directly involving consumers in the development of informative materials is the gold standard. “Bringing users into the design process ensures comprehension and overall correct usability, and will assist in our goal to save children’s lives and prevent serious injury,” Professor Schofield said. Fifty per cent of transport injuries occur to child passengers in cars in developed countries. This study will reduce that number by ensuring restraints are installed and used correctly every time a child travels on road. “Our findings tell us that increasing comprehension of child restraint instructions is an effective measure to counter misuse, and that users should be involved in every step of the design and testing,” said Associate Professor Brown added. “This could be a cost-effective and far-reaching intervention that will keep kids safer on the road both here in Australia and in many other countries around the world.” Injury is the leading cause of death and hospitalisation in Australia of children aged over one year. Associate Professor Brown and her team at NeuRA are now taking this study from the lab to the real world to work on improving these outcomes and making child restraints in cars more effective.

PROTECTING VULNERABLE ROADWORKERS AND ROAD USERS When Traffic Management Association of Australia (TMAA) President Stephen O’Dwyer met Safer Australian Roads and Highways (SARAH) President Peter Frazer, it was a meeting of the minds and spirits. Mr O’Dwyer had not long written an article for HEA revealing the need for protection of traffic controllers as they go about their works on roads protecting others. Peter Frazer has written numerous articles and lobbied government heavily for changes to safety to protect vulnerable road users and road workers. Peter now writes quarterly for the TMAA magazine as well. The key message for both TMAA and SARAH is to educate the public and raise awareness of the need to slow down around roadworks, drive safely at all times, and obey the road signage and rules. The significant road statistics for both the general public and roadworkers continues to rise, despite the many educational awareness programs and driver awareness programs released by state and federal governments. TMAA President, Stephen O’Dwyer, believes safety on roads education must start at an early age, and the TMAA is in the phase of gaining federal and state momentum and funding for the second in a three-part series advertising campaign which features a little girl and her father. The first advertisement leaves us uncertain as to the fate of the father, while the second and third instalments will be hard hitting.

36 Highway Engineering Australia | Dec 2018/Jan 2019

“In my last article for HEA I outlined how both Peter and I are working tirelessly to stop roadworker incidents and crashes. This advertisement is only one of the projects that will assist with this. The TMAA is also working closely with Austroads and is part of the Safety at Roadworks Project Working Group, discussing changes to the way we work on roads and how the public drives on them,” he said. “There will be greater need for regulation for industry, and training for the public, with governments understanding that new road work equipment can be misunderstood or not seen by the travelling public.” “So often we hear that the driver was in a hurry and simply did not see the sign, the car, the person,” he said. “Working with Peter, I believe we can intercept the current trend to rush and speed, and transform driver behaviour, but it may take some unpleasant educational narratives to make this happen.” “Peter is doing the rounds speaking to our members in different states and we are proud to display the SARAH yellow ribbon at our meetings.” Peter Frazer said he sincerely thanked the TMAA for its great support of SARAH road safety initiatives and the opportunity to write for their Magazine.” “The job of traffic controllers is a dangerous one. As they find themselves in harm's way every day, it is up to every Australian to ensure that those who are vulnerable are actively protected,” he said.

“Each of us has someone who we love and for those we love, we must ensure drivers and riders slow down and give those who work on our roads, the space they need to be safe.” Peter said getting this message out has never been more important. “In fact, it was just a few weeks ago when we commemorated the first anniversary of the death of Mr Ken Altoft, the Traffic Controller killed on the Bruce Highway in Queensland last year.” “While industry is committed to safe outcomes, we must also ensure that Ministers, government authorities and the general community, actively prioritises the safety of Traffic Controllers, and all those who work on our roads.” Peter said, “So together with the TMAA and our national partners, we will continue to ask a simple question “How do you show you Drive So Others Survive?” “For Everyone has a right to get home safe… Every day… No Exceptions!” It is the intention of TMAA and SARAH to stop the fatalities and injuries on our roads and roadwork sites.” For more information on the campaign follow TMAA on Social media and visit: www.tmaa.asn.au

Brian Negus also holds several board positions including ITS World Congress Board of Directors; ITS Australia Board of Directors; Chairman of Collaborative ITS Consulting Australia (CICA); and Director of Victorian Chamber of Commerce and Industry.

2018 ITS Australia National Award winners:

Queensland Department of Transport and Main Roads – for Successfully Integrating and Leveraging Off Multiple ITS Technologies to Perform Real-Time Performance Metrics and Analytics for the Commonwealth Games Project Description: This project was an example of how to successfully take several ITS data sources, synthesize them, and then successfully perform analytics to provide realtime answers to congestion issues.

Max Lay Lifetime Achievement Award

The 2018 recipient of the Max Lay Lifetime Achievement Award is Brian Negus. Brian was a Director of ITS Australia for 12 years from 2007 – and for 6 of those he was President. Brian is now ITS Australia Ambassador, representing ITS Australia nationally and internationally.

Government Award Winner


The innovative part of the project was how that information was drawn and leveraged from multiple ITS technologies to undertake real-time performance metrics and analytics for the Commonwealth Games. Queensland Transport and Main Roads Minister Mark Bailey said he was delighted to hear his department named winner of the Government Award at tonight’s awards. ‘‘The Gold Coast 2018 Commonwealth Games was the largest multi-sport event this country has seen in more than a decade,’’ Mr Bailey said. ‘‘TMR’s challenge was to provide a transport network that could safely and reliably move millions of GC2018 spectators during peak travel times over 12 days in multiple cities — while continuing to service the public. ‘More than seven million estimated trips were taken across the course of the event with considerable work carried out to deliver real-time information drawing and leveraging from multiple ITS technologies.”

Industry Award Winner

EastLink – for the Freeway Tunnel Ventilation On-Demand System Project Description: Traditional tunnel ventilation systems are inefficient. Fans operate at fixed speed in manual mode or with individual fans programmed to switch on and off at pre-set times to ensure zero portal emissions with all emissions dispersed via ventilation stacks. EastLink’s new ventilation on demand (VoD) system matches variable speed fan drives with more efficient impellers which are dynamically controlled based on real-time data from tunnel gas/airflow sensors. “EastLink is delighted that our innovative tunnel ventilation on demand system has won the 2018 ITS Australia National Award (Industry). This award will help encourage Australia’s other freeway tunnel operators to implement ventilation on demand and replicate our success – including a 68% reduction in power usage, and a halving of audible noise for local residents,” said Doug Spencer-Roy, EastLink spokesperson.

Automated Vehicle Award Winner

Centre for Technology Infusion, La Trobe University – for The Autonobus Pilot Project Project Description: With the aim of bringing autonomous shuttles a step closer to reality in Victoria, VicRoads supported the Autonobus Pilot Project Level 4 Automated Shuttle Trial. An automated shuttle was tested in the real life and busy campus environment of La Trobe University as an actual use case of first and last mile connectivity. The project demonstrated that standards of safety, technical, operational, and community acceptance can be met for successful and future deployment in similar environments.

Research Award Winner

Advanced Data Analytics in Transport, Data61 CSIRO – for an Artificial Intelligence Engine for Traffic Congestion Management Project Description: Data61 and Transport for NSW jointly developed a prototype AI engine for congestion management. The AI engine trains machine-learning models that complement traffic simulation for network prediction. The development is the first of its kind in Australia. It makes use of the power of deep-learning and big-data analytics to provide real-time foresight of transport network situations with insight into the impact of major disruptions to multi-modal, end-to-end journeys in NSW.

Young Professional Award Winner

engineering, Michael founded Retina Visions in 2016 and incorporated it in October 2017. Retina Visions provides governments, councils, and road authorities with the ability to build digital models of the road network in real time, identifying individual road assets such as signage and electrical assets, while also providing maintenance crews with defect information for items such as potholes, broken signs, or faded line marking. Retina Visions uses machine learning, artificial intelligence, and computer vision to automatically identify objects on the road network. “I feel incredibly honoured to receive this year’s Young Professionals award and to have been chosen by a number of experts and professionals in the industry. My goal is to grow Retina Visions from a small Brisbane based company to an international provider of smart technology in transport, and winning this award is definitely a big step towards my goal. We have a very strong team within Retina Visions, and I wouldn’t be in this position without our CTO and co-founder of the company - Marc Miska. We started Retina Visions to make a difference in road maintenance and management, improving the way data is collected and automating tedious processes with new technology." In addition to the Award, ITS Australia will sponsor Michael to attend next year’s ITS World Congress in Singapore, which is expected to attract over 10,000 transportation technology professionals, to network and participate in advanced transport technology demonstrations.

ERM USING HUMAN VOICE WARNINGS TO IMPROVE DRIVING International automotive technology provider ERM Advanced Telematics, whose products have been installed in more than 5 million vehicles worldwide, is launching two new products aimed at improving driving quality with the use of human voice warnings and visual signals to the driver. With the development of the two products, eVoice and eFlash SF, completed, both are now being implemented by a number of clients and are available in the 68 countries where ERM is active. The main target markets for the products are car fleets, automakers and auto importers. The eVoice and eFlash SF products join the company’s mature eSafe product for identifying and analysing driver behaviour. The latest products represent expansion of the existing solutions for safety and communications solutions launched by ERM in recent years for connected vehicles. The eVoice product is based on a speaker installed in a vehicle that utilizes a processor and a memory chip for supplying the driver with human voice warnings designed to help him or her identify dangerous situations or driving decisions they made while driving. This service enables personalised learning by the driver with the aim of improving habits and behaviour while driving. The device allows a fleet manager or the operator of the platform to record in advance up to 100 warnings in the mother tongue of the driver that are adapted to various dangerous patterns on the road or based on various situations of the vehicle, and to define with a user-friendly software program which warning will be played for each type of event. For example, if a driver made an excessively sharp turn for example, a warning would be sounded to explain the incorrect behaviour. In the event the driver went over the speed limit on a specific section of the road, they would receive a voice warning as would be the case with other unsafe driving events. eVoice is capable of issuing a human voice warning upon identifying any unusual event of the type that can also be identified by a wide range of the company’s products, based on its StartLink technology. It can also identify any unusual event of the type that can be detected by ERM Advanced Telematics’ add-on products like eSafe or eData. eSafe is used for identifying and analysing a driver’s behaviour, while eData provides an interface for vehicle communications channels like CAN Bus and On-Board Diagnostics (OBD).

42 Highway Engineering Australia | Dec 2018/Jan 2019

Among other features, eVoice can also warn of unusual events related to the vehicle’s mechanical condition such as engine problems or overheating as well as a wide range of extreme events that are identified by the eData interface based on CAN Bus data. eVoice customers can record in advance warnings in their own voice for each device or alternatively type a text message and convert it to voice using the text-to-speech capabilities which are also offered by eVoice. The eFlash SF product serves as a warning system for the driver and includes 6 icons with LED lighting installed on the dashboard. It warns the driver, through the use of flashing icons and a series of beeps, of various situations that he or she needs to be informed of or require attention. For example, icons can be defined for problematic behaviour such as dangerous manoeuvring, accelerations, excessive breaking and sharp turns. In addition, the fleet manager, the automaker or the operator of the system can define in advance actions for which visual warnings using lighting and icons can be given. These could include sections of roads with speed limits, speed cameras, holes in the road, dangerous intersections, designated areas for cargo collection, bus stops etc. The eFlash SF also has push buttons that allow changes and adjustments to be made to the warning buttons and lighting of the system as deemed necessary. One button can be designated as an emergency or danger signal, in the event the driver needs immediate assistance due to a vehicle malfunction or an extreme situation like an accident. Pressing on this button can enable the driver to be connected directly to an emergency centre and initiate a communications channel with a service centre. Additional options can be defined such as speed dialling, in case of using a voice enabled device, an identification code for the driver, etc. ERM’s modular solutions support the use of one or the two products eFlash SF and eVoice simultaneously, in order to give the warning even greater significance by use of both the flashing of the LED lighting and the voice warning capabilities of the two systems. "The ability of eVoice to supply warnings using a human voice for teaching correct driving habits is unique in the market,” says Eitan Kirshenboim, CMO at ERM Advanced Telematics. “The combination of eVoice and eFlash SF offers the driver a complementary array of voice and visual warnings that maximize the chance of responsible and safe driving,” he said.

“ERM is aiming to create competitive advantages for our partners and customers in markets where they operate, by taking advantage of various technologies and present innovative solutions to prevent accidents, advance safe driving and to improve the operating arrays of auto fleets and organizations alike.” “We are constantly expanding our modular product line and supplying new and up to date technological solutions in order to meet market demands as well as those of our partners. The launching of the newest solutions represents an important step forward towards achieving this very important goal,” Mr Kirshenboim added.

INTELEMATICS TECHNOLOGY PREDICTS FAILING BATTERIES SO DRIVERS AREN’T LEFT IN THE LURCH Intelematics has showcased intelligent predictive services technology that can predict failing batteries so drivers aren’t left in the lurch. This came on the back of a recent trial conducted in the United States which saw Intelematics explore how algorithms can be used to predict vehicle battery failures. The project saw drivers provided with devices that were plugged into their vehicles, and worked in conjunction with a smartphone app. The data that was captured, which encompassed battery performance information, was then used to assess battery health and predict when it was within four to six weeks of failing. Intelematics Australia’s Chief Operating Officer, Steve Owens said the trial was a success and the company is looking forward to introducing this innovative technology to the market. “Our time is precious and the last thing people want is to be stranded on the job, at the supermarket or at home because of a mechanical fault. Our world leading, Australian developed technology, means that flat car batteries will be a thing of the past. “At Intelematics, we invest heavily in research and development. This latest trial in the US found that our technology, in its current state, can accurately predict 70 per cent of failing batteries

44 Highway Engineering Australia | Dec 2018/Jan 2019

four to six weeks in advance. This means that drivers can be notified of a failing battery well ahead of time and avoid being stranded at an inconvenient time,” said Mr Owens. Australian auto clubs attend to over 5.6 million call outs per year; and of these around 30 per cent are battery related. People today are time poor, and our technology can help predict and prevent battery failure so that they can keep on moving. “Auto clubs are early adopters of Intelematics’ predictive battery technology, and are able to offer extra services to their members. They can alert their members of an impending battery failure, and avoid an unplanned interruption,” said Mr Owens. Intelematics’ predictive battery technology is set to help businesses such as auto clubs, auto manufacturers and service providers, anticipate battery failure, which will reduce call outs, minimise lost time on the road and strengthen trust and credibility among their customers. “Battery failure can be costly to businesses through lost time on the road and driver frustration. The predictive technology can really help fleet managers because it gives them the ability to be made aware of vehicle problems before they occur, saving time on repairs and maximising

productivity by keeping their vehicle on the road,” said Mr Owens. In the future, Intelematics aims to expand the technology’s capability to predict other vehicle faults, including problems with tyres, ignition coils and other engine components. Intelematics also plans to explore how its predictive algorithm technologies can be translated to hybrid and electric vehicles. Please visit: www.intelematics.com.au

Eastlink’s 2018 Annual Victorian Self-Driving Car Survey EastLink, with support from ARRB, has now completed the second Annual Victorian SelfDriving Vehicle Survey – the largest survey of its type in the world – and the findings make one thing clear – compared to last year, fewer motorists want a fully self-driving car. It seems that the hype bubble surrounding self-driving cars has burst. In summary, the survey found that: • Compared to last year, fewer motorists want a fully self-driving car, while more motorists want the latest driver assistance features like lane departure warning, lane keeping assistance, adaptive cruise control and automatic emergency braking. • A significant proportion of motorists expect that fully self-driving vehicles should be absolutely 100% safe with no possibility of ever being involved in a collision, even though this is an unrealistic expectation. • The desirability of hybrid and fully electric cars has increased further, with hybrid power now rivalling traditional petrol combustion. • More motorists think it’s unfair that electric vehicles avoid fuel tax compared to those who think it’s fair. • More motorists think fuel tax should be replaced by a per-kilometre road use charge compared to those who prefer the status quo.

46 Highway Engineering Australia | Dec 2018/Jan 2019

• The majority of motorists think any future road use charge should provide a discount for electric vehicles to encourage take-up. Speaking about the survey, EastLink Corporate Affairs and Marketing Manager Doug Spencer-Roy said, “More than 18,000 Victorian motorists fully completed the survey this year, which is a 20% increase on last year.”

Cars taking part in a demonstration trial of automated speed control technology on Melbourne’s EastLink.

“The EastLink survey continues to be one of the world’s largest surveys of motorists’ attitudes to self-driving and driver assistance technologies, vehicle connectivity, electric power and road use charging – technologies which are expected to converge in cars of the future,” he continued.


Compared to last year’s survey, although more respondents can imagine using handsoff driving on a freeway, fewer respondents want their next vehicle to be capable of fully self-driving. Doug Spencer-Roy explained, “This reduction in desirability for fully self-driving vehicles indicates that expectations had become over-inflated by hype, and people are now becoming more realistic.” Eight in ten survey respondents would travel as a passenger in a fully self-driving car where the vehicle has a driver who is monitoring and able to take over control. However, the majority of respondents would not yet travel as a passenger in a fully self-driving car where the vehicle is completely driver-less and there are no driving controls. A significant proportion of respondents – 37% of female and 28% of male – expect that fully self-driving vehicles should be absolutely 100% safe with no possibility of being involved in a collision. “When it comes to minimum acceptable safety, a significant proportion of people have unrealistic, unachievable expectations, which will be a significant hurdle for the autonomous vehicle industry to overcome,” said Doug Spencer-Roy.

In contrast to these mixed results for fully self-driving cars, usage of, and demand for the latest safety and driver assistance features has increased in almost all cases compared to last year, with larger increases seen among female respondents. Doug Spencer-Roy explained, “EastLink anticipates that widespread adoption and use of the latest safety and driver assistance features – such as lane departure warning, lane keeping assistance, adaptive cruise control and automatic emergency braking – will significantly improve road safety by reducing the number and severity of crashes.” “These survey results support EastLink’s expectation that these features will become commonplace before fully autonomous vehicles.” Compared to last year, demand for connected car features is largely unchanged. A clear majority of male and female respondents still “definitely want” their next car to be connected to a data network for traffic warnings, road condition warnings and vehicle security features. “This demonstrates the importance of EastLink’s trials of 5.9GHz infrastructure to vehicle communications which started this year,” said Doug Spencer-Roy. Respondents are now even more likely to prefer hybrid power or 100% electric for their next vehicle. Only 39% of respondents are considering a traditional petrol combustion drivetrain for their next vehicle, whereas 80% of respondents have that option in their current vehicle. Doug Spencer-Roy said, “This year’s survey shows that the preference for hybrid power has increased and now rivals the preference for traditional petrol combustion power. The preference for 100% electric has also increased.” Hydrogen fuel cell electric vehicles may become a popular option for 100% electric cars in Australia, with the potential ability to quickly top up Hydrogen at service stations eliminating “range anxiety”. However, there is a significant awareness gap. While only 8% of respondents are unaware of battery electric vehicles, five times that proportion are unaware of hydrogen fuel cell electric vehicles. “Manufacturers and other stakeholders should raise awareness of hydrogen fuel cell electric vehicles, to help with its emergence as a practical option for 100% electric vehicles in Australia,” recommended Doug SpencerRoy. Significantly more respondents think it is not fair that fully electric vehicles use roads without incurring any fuel tax compared to those who think it is fair.

Slightly more respondents think fuel tax should be replaced by a per-kilometre road use charge that every vehicle is charged compared to those who prefer the status quo. However nearly one in four respondents are undecided at this time. If a road use charge is introduced by Governments in the future: • a large majority of respondents think offpeak trips should cost less per kilometre than peak period trips; and • more than half of respondents think fully electric vehicles should get a discount to encourage take up of fully electric vehicles, while less than a third think there should be no discount for fully electric vehicles.

ABOUT EASTLINK EastLink’s 40-kilometre road network is the largest privately-operated freeway network in Victoria, Australia. EastLink is the major north-south transport artery in Melbourne’s east, connecting the Eastern, Monash, Frankston and Peninsula Link freeways. EastLink is Melbourne’s fastest road and safest freeway, with traffic averaging 250,000 vehicles per day. In 2018, the internationally recognised sustainability assessment agency, GRESB, awarded EastLink the top 5 Star sustainability rating for the third consecutive year and ranked EastLink #5 globally of 280 infrastructure entities.

THE PRECAST PROCESS BEHIND PERTH’S NEWEST INFRASTRUCTURE PROJECT: NORTHLINK WA STAGE 2 – CENTRAL SECTION PRECASTER: DELTA CORPORATION LOCATION: REID HIGHWAY TO ELLENBROOK, WESTERN AUSTRALIA CLIENT: MAIN ROADS WESTERN AUSTRALIA BUILDER: GREAT NORTHERN CONNECT (BGC CONTRACTORS & LAING O’ROURKE JOINT VENTURE) ENGINEER: AAJV (AECOM & ARCADIS), GHD The NorthLink WA project comprises the construction of a new vital transport link for the North West of Western Australia. When complete, the $1.2 billion project will reduce travel times and congestion, as well as provide productivity benefits to the economy, industry, motorists and local community. As the second stage in the NorthLink WA project, the Central Section involves the construction of a free-flowing road link from Reid Highway to Ellenbrook and is extending the Tonkin Highway between Morley and Muchea. Set to improve access to Ellenbrook and the surrounding precincts, this $417 million section comprises approximately 20 kilometres of highway with four interchanges, including 14 road bridges and three footbridges. As a vital phase in the larger project, the Central Section is being delivered by the Great Northern Connect team—a BGC Contracting and Laing O’Rourke joint venture.

48 Highway Engineering Australia | Dec 2018/Jan 2019


National Precast member, Delta Corporation, was awarded the contract to supply precast concrete elements integral to the Central Section. These included 151 TeeRoff Beams for 16 individual bridges and 200 precast column shell formers for the bridge abutments. Each bridge is unique in design and layout, requiring varying sizes and configurations of beams. Lengths ranged from 17 metres up to 43 metres, depths from 1.0 metre to 2.1 metres and widths from 3.2 metres to 4.8 metres. Beam weights ranged from 63 tonnes to 181 tonnes. All precast elements have a Class 2 finish, as per AS 3610 Formwork for concrete, have been designed for a 100-year service life, and were required to meet the stringent durability and quality standards.


The project’s engineers designed an innovative continuity joint detail between the bridge beams—the first of its kind ever to be used with TeeRoff beams on any bridge project in Western Australia. All projects have previously been designed with simply supported beams. As a result of the continuity joint design, there were a number of savings made, including: • reduced prestress requirements, • elimination of top prestress strands, • reduced beam depth, • reduced structural depth (-150mm to -200mm), • reduced number of bearings required at piers by half, • reduced pier column width, • eliminated formwork required to construct the continuity between beams, and • eliminated the requirement for transverse diaphragms at the piers.



The continuity detail at the beam pier ends involved a complicated formwork design to create a void with a variety of cast-in fittings to enable the beams to be spliced on site. Additionally, the bridge geometry meant that a number of the beams needed to have acute end skews on the abutment ends and the top flange edges curved to a specific radius to suit the alignment of the bridge. Delta’s Executive Director, Matt Perrella, says although the continuity joint detail resulted in significant construction savings, it made for a complicated manufacturing process. “The extent of strand de-bonding in this project varied from beam to beam and was far more complex, compared to others in the past” Mr Perrella details.

“In addition to this added complexity, the strands at the continuity joint were required to extend through the shutters to the end of the beam where they were fitted with spacer plates then onion jacked after demoulding to provide anchorage for the insitu concrete stitch.”


With the project’s long-term ambition to cater for Perth’s growing traffic volumes, longevity of the precast elements was critical. “Specifications for durability control on this project have been one of the most stringent encountered to date. During the pour, the concrete temperature was to be maintained at below 32°C and, during the steam curing cycle, below 80°C,” Mr Perrella explains. Curing plays an important role in the strength and durability of concrete, and the project’s specification required the beams to remain in the moulds for a minimum of 48 hours after casting. To meet both this requirement and project deadlines, the precaster developed a unique control methodology, which included producing their own high strength and high flow concrete with state-of-the-art computerised batching plants. “With this methodology, we were able to meet the construction schedule and assure the client that de-moulding could be achieved within our normal overnight curing cycle,” Mr Perrella says. Delivery of all the precast prestressed concrete elements was completed three weeks ahead of program.

PROJECT PROSPECTS NorthLink WA is being constructed in three sections—these being the Southern Section - Guildford Road to Reid Highway, the Central Section - Reid Highway to Ellenbrook, and the Northern Section - Ellenbrook to Muchea. The Central Section’s new highway will take the pressure off the Great Northern Highway by shifting the majority of heavy vehicles over to the new route. Due to be completed by the end of 2019, the wider NorthLink WA project is set to improve freight capacity and efficiency, reduce urban congestion, improve road safety, create value through sustainable infrastructure, and cater to an expected Perth population of 3.5 million by 2051.

IMPROVEMENTS TO THE IAP GET THE GO-AHEAD Transport Certification Australia (TCA) has confirmed that improvements will be made to the Intelligent Access Program (IAP). The IAP is an application of the National Telematics Framework, which provides a contemporary approach to the management of heavy vehicle access. In May 2018 TCA was assigned responsibility to develop a business case with improvements to the IAP by November 2018. TCA’s Chief Executive Officer, Chris Koniditsiotis, said: “The approved business case contains a range of enhancements to the IAP, as well as new applications and features to be offered through the National Telematics Framework. The business case was informed by extensive consultation with road managers, regulators, peak industry bodies and the telematics sector.” “I want to acknowledge the valuable engagement we had with all stakeholders and the open, forthright discussions which directly informed the business case.” “We found that although stakeholders recognised the need for the IAP application - which provides the highest level (Level 3) assurance and certificate-based evidence there was concern the IAP was being used in ways that were not originally intended,” he said. “In addition, transport operators were being asked to use the IAP application

when certain access arrangements could be delivered with lower levels of assurance.” “It was clear that other applications to manage heavy vehicle access and network utilisation, with lower levels of assurance, were needed to meet the needs of stakeholders,” Mr Koniditsiotis added. A stakeholder report was prepared by TCA, which consolidates the feedback received from stakeholders, to accompany the business case. A copy of the stakeholder report is available for download from: www.tca.gov. au/documents/Report-20181109-Improveme ntstotheIAPStakeholderReport.pdf The approved business case incorporates a total of 16 improvements, including: • Enhancements which relate specifically to the Level 3 assurance IAP application, to improve efficiency and reduce costs; • New applications of the National Telematics Framework, including the Road Infrastructure Management (RIM) application (Level 1 assurance) and ‘IAP Lite’ application (Level 2 assurance)

• New features which can be used across applications of the National Telematics Framework (such as turn-by-turn navigation and restricted access vehicle route guidance). “With the introduction of the new RIM and ‘IAP Lite’ applications, road managers and regulators will have the choice of three separate access applications to cater for different infrastructure capacity and operator risks,” Mr Koniditsiotis said. “Seven of the 16 improvements are already being progressed as part of TCA’s work program for 2018-19, with the remaining improvements to be prioritised in future work streams,” Mr Koniditsiotis added. TCA will be holding a series of information sessions during the first half of 2019 to explain how different stakeholders can benefit from the improvements contained in the business case.

Stephen Golding said: “Being Chairperson of a government body with carriage of unprecedented functions within the transport portfolio has been a unique opportunity.” “Along with my fellow Directors, I am proud to have observed TCA grow into the respected, dynamic and innovative organisation that it is today.”

“Perhaps because of its success, it is easy to take TCA’s role for granted. Nevertheless, I am confident that we have successfully translated the vision behind the original decisions into a reality,” said Mr Golding. TCA’s formation in 2005 followed decisions made by road and transport agencies and Responsible Ministers to establish new operational capabilities within government to lead productivity, safety and efficiency benefits through the use of telematics and related intelligent technologies. “It’s been an honour to work with Directors on the TCA Board, who have displayed the highest levels of professionalism and integrity.” “It has also been pleasing to see so many prior Directors, who have had a hand in shaping TCA, move in to prominent roles across the public and private sectors,” Mr Golding said. The outgoing Chief Executive Officer TCA, Chris Koniditsiotis, said: “Stephen Golding has been a pinnacle example of leadership, integrity, and strength to me, the executive and the Board.” “We have benefitted from Stephen’s experience, insights and most importantly, wisdom.” “TCA wishes Stephen well for the future,” said Mr Koniditsiotis. Mr Golding retains Board positions on the North Queensland Bulk Ports Corporation, the Queensland Reconstruction Authority and Transmax Pty Ltd.

CHRIS KONIDITSIOTIS ANNOUNCES RETIREMENT FROM TCA Transport Certification Australia (TCA) has announced that Chris Koniditsiotis is retiring from the position of Chief Executive Officer. Well-known across the transport and technology sectors, Chris Koniditsiotis has led TCA since its establishment in 2005. TCA’s Chairperson, Stephen Golding AM RFD, praised Mr Koniditsiotis for his work in leading and shaping TCA. “On behalf of the Board of TCA and all past Directors, I congratulate Chris on an outstanding leadership role in bringing TCA to its present state and thank him for his efforts. I wish Chris all the best for the future,” said Mr Golding. Chris Koniditsiotis said “The opportunity to lead a national government organisation which has helped shape the digital transformation of surface transport has been a true privilege. It is now my time to pass-on ‘the baton’ in the way the baton was originally passed to me.” “I am honoured to have worked with decent, competent and content-rich people

who have demonstrated strong values-based behaviours.” “I’ve also had the privilege to meet and work with some great people across government, industry and the technology sector, whose passion and love for their work has been contagious,” he said. “I’m proud of how we’ve been able to deliver improved productivity and safety outcomes by harnessing the digital economy with a contemporary open market approach with the highest levels of data privacy.” “As I move towards the next chapter of my life, I reflect with pride on what has been achieved, and collectively, how a diverse range of individuals have contributed to these achievements.” “For now, my immediate role is to manage transitional arrangements before my final day on 1 March 2019,” he added. “I wish to thank the TCA’s Chairperson, Stephen Golding and the TCA Board for all their support over the years.”

“I will be leaving TCA with strong foundations, and in a position of strength to move forward into the future,” Mr Koniditsiotis concluded.

High load-bearing capacity for the approach road to Interstate 69: the Wirtgen WR 250 delivered a top performance stabilizing soil in Indiana.


Soil stabilisation has the edge over soil exchange Soil stabilisation is proving to be the optimum solution whenever the properties of soil have to be altered to make it suitable for further roadworks. That was the case in Bloomington/ Indiana, USA, for instance, where a WIRTGEN WR 250 soil stabiliser laid a load-bearing base for the construction of a new approach road to Interstate 69. Soil stabilisation is the method of choice when it comes to ensuring the load-bearing capacity and quality of soil in preparation for road construction projects. The targeted addition of stabilising agents can, for instance, help to reduce the moisture content of soil, which is vital for further roadworks. Compared to the process of exchanging the entire soil, soil stabilisation is an economical and resource-saving method. Cost savings result from the simpler job-site logistics, for instance, with fewer lorry trips and shorter construction periods. Resources are also conserved, because all of the existing soil is

used in the stabilisation process with only stabilising agents such as lime or cement being added â&#x20AC;&#x201C; or a combination of both in the form of a mixed stabilising agent. Many invitations to tender continue to specify that the soil is to be exchanged â&#x20AC;&#x201C; but this is no longer a state-of-the-art method. The Wirtgen soil stabiliser uses its powerful milling and mixing rotor to mix pre-spread stabilising agents such as lime or cement into existing soil with insufficient bearing capacity,

transforming it into a high-grade building material right on the spot. The homogeneous mixture of soil and stabilising agent that is produced offers a high load-bearing capacity as well as lasting resistance to water and frost, and volume stability. Typical applications include the construction of paths, roads, motorways, routes, parks and sports grounds, industrial estates, industrial plants, airfields, dams, backfilling and landfills.

In the homogenization process, the powerful milling and mixing rotor of the Wirtgen soil stabiliser granulates the native soil without the addition of stabilising agents and loosens it. While a grader profiles the homogeneous soil prepared this way, rollers for soil compaction take care of the compaction process.

A machine train is generally required if the properties of the soil are to be lastingly improved. This begins with a binding agent spreader that deposits the stabilising agent evenly, followed by a Wirtgen soil stabilizer. The WR 250 uses its milling and mixing rotor to mix the soil homogeneously with the pre-spread lime. A pressurized scraper on the rear milling drum flap ensures that the treated material is smoothed evenly. While a grader profiles the soil mixture, rollers for soil compaction ensure optimum compaction.

Stabilisation with cement creates water-bound base courses. The binding agent is laid by a towed spreader, which is followed by a water tanker. Behind it, the milling and mixing rotor of the Wirtgen soil stabiliser mixes the soil with the pre-spread cement to form a homogeneous mass. At the same time, water is sprayed into the mixing chamber by means of an injection bar. Here, too, graders profile the treated material and rollers complete the job by ensuring optimum compaction.

In soil stabilisation, a distinction is made between improving the soil and stabilising it. Lime improves the paving properties and compactability of wet, cohesive soil. This is known as soil improvement. If the aim is to stabilise the soil cement is used because it lastingly enhances the load-bearing capacity, volume stability and resistance to water and frost. Soil can be stabilised or homogenized even without the use of stabilising agents.

Case study: Soil stabilisation in Bloomington, Indiana, USA In the soil stabilisation project on Interstate 69 south of Indianapolis, the newly embanked

earth first had to be stabilised in order to create the necessary load bearing capacity for the asphalt pavement of the new approach road. The contractor, Specialties Company, LLC, used lime as a stabilising agent and took advantage of Wirtgen’s applications expertise. Lime immediately reduces the water content in the soil and binder mix. This ultimately improves compactability and increases the load-bearing capacity of the treated soil. “To achieve the optimum outcome, we always liaise closely with the applications professionals from Wirtgen. They are always

on hand to offer their consulting expertise,” explains Jamie Cardiff, Equipment Manager at Specialties Company.

WIRTGEN WR 250 soil stabiliser required When it came to choosing the machine, too, the Specialties Company’s team put their trust in the innovative technologies from Wirtgen, opting for the WR 250 wheeled soil stabiliser. The 571kW powerhouse also used, among other applications, in cold recycling for granulating asphalt, is the most powerful machine in the WR generation and specially designed for the stabilisation of heavy and boggy terrain.

With this machine, daily performances of up to 15,000m2 are far from uncommon in soil stabilisation applications. After the lime had been pre-spread, the high engine power and optimum traction of the WR 250 enabled it to effortlessly work through the heavy and sometimes deep soil. The WR mixed the soil and binding agent homogeneously across the entire working width of 2.4m to a depth of exactly 30cm.

“The WR 250 is a real power pack and works extremely efficiently.” Jamie Cardiff, Equipment Manager Specialties Company, LLC

Strong performance, easy operation “Operating the machine is child’s play. The multifunctional joystick on the right armrest, for instance, gives me easy control of all the main basic functions,” says Richard Clark, describing the high level of operating comfort. One of the challenges was the uneven condition of the earth, which varied from very firm to loose. “The milling speeds can be controlled from the operator’s cabin, so our machine operators were able to respond directly to the frequent changes in soil conditions. This ensured a high mixing quality at all times,” Cardiff adds. It took just five days to complete the stabilisation work and lay the load-bearing
