In-car traffic management by sharing data Traffic management in the digital age

Folkert Bloembergen, Projectmanager Talking Traffic Rijkswaterstaat 30th March 2022 – Intertraffic Amsterdam 2022

Mission of Rijkswaterstaat Rijkswaterstaat operates to ensure the Dutch inhabitants have: • protection against flooding; • sufficient clean water; • a smooth and safe transport by road and water; • reliable and useful information; • a sustainable living environment.

Rijkswaterstaat is fulfilling three social roles: • a public-oriented network manager; • a leading project manager; • and an effective crisis manager.

Rijkswaterstaat in a nutshell •

Around 8,800 employees

•

7 regional departments, 16 districts, 4 process departments, 1 department for innovation and 1 corporate department

•

Annual budget: 5.5 billion euro in 2020

Rijkswaterstaat’s area of management Rijkswaterstaat is in charge of three national infrastructure networks:

4

Vision Traffic Management 2030 • Developed with Ministry of Infrastructure and Water Management • Goal: A robust network through traffic management, enabling road users to travel well informed and trusted travel time predictions • Digitalization of Traffic Management • Stimulate in-car information

• A larger share of vehicles with ADAS & connectivity

6

Mobility and accessability We make sure most traffic is directed via the ringroad. This goal is

achieved by using smart technology and a traffic circulation plan.

Monitoring is done by measuring air coality in the city.

Action plan local government

Changing environment: traffic management is becoming more integrated • Traffic management in the digital age requires new

partnerships.

• Road authorities provide their policy goals towards serviceproviders.

• Serviceproviders can integrate this information in their route and information service.

• Working on achieving common goals; safety and

environmental.

8

Working together National

• Policy making • Legislation • Finance

Road authorities

• Rijkswaterstaat • Local road authorities (provinces, municipalities) • NDW (National Road Traffic Data Portal)

Road users

• More safety • More sustainable • Better mobility

Talking Traffic as a backbone Continuous sharing of data between road users and infrastructure: • Based on cellular technology • No special equipment required

• Large number of users • Swarm intelligence: “traffic regulates traffic” • Deployment, not just pilots

• Scalable 10

Talking Traffic; output….

6 groups of information categories: • In-vehicle signage

(static and dynamic speed limits)

• In-vehicle warnings

(hazardous situations, roadworks, etc.)

• Priority at Traffic Lights

(emergency services, PT, trucks)

• Information from Traffic Lights

(TTG, TTR, GLOSA, reason extended red)

• Network optimization

(through traffic lights and VM-IVRA)

• In-vehicle parking information

(static & dynamic, reservations)

11

… for several user groups Personalized information available for drivers of: 1. Passenger cars 2. Trucks 3. Public Transport 4. Emergency Vehicles And (naturally, in the Netherlands) also for people on: 5. Bicycles 12

Real-time warnings and speed advice in-car

• 2 million plus road users and growing • 80% of road users appreciate this information Copyright: Flitsmeister

15

Traffic lights • 1.100 traffic lights are now interactive • 700 planned • 5.500 traffic lights in the Netherlands • More policy and traffic driven algorithms • More safety: Green light for emergency services

For safety and flow…

To look further than just the wind shield…

18

Dynamic traffic management • Undesirable side-effect: traffic sneaking through villages and residential areas.

• Road managers: existing resources, such as roadside systems and signs, are insufficient to meet these challenges.

• Serviceproviders: do not (always) have digital access to the right government information to provide good, customized advice.

Solution: the joint road managers are therefore working on uniform access to traffic management data, enabling serviceproviders to provide good route advice that takes account of local circumstances.

Public and private partners

Before we started: study • Key question: what added value see road managers and serviceproviders in the exchange of traffic management information?

• Main aim: better serving road users and increasing road safety • All parties involved are enthusiastic, because: together we achieve more!

21

Win-win-win situation (1) • Win for road users: – They receive traffic information in a uniform manner via the appropriate channel; – Know where they stand; no more surprises.

• Win for service providers: – They can inform customers better, which means better service and higher customer loyalty; – Opportunities for new business models.

22

Win-win-win situation (2) • Win for road operators: – The use of intelligent services and products by public authorities offers them opportunities to achieve higher network performance; – They can contribute directly to policy objectives (air quality, less accidents, noise); – Easier exchange of information with internal and external parties;

– More effective use of public funds through targeted use of traffic control scenarios.

23

What have we learned so far?

• 4G communication is good for all use cases • The quality of data is essential but has many hurdles – Timing is everything – Aligning all different road authorities (National, Regional, Local) – User expectations for digital information is higher than for analog information, faster updates, consistent quality

• Presentation of information (HMI) is crucial
