Smart City Maribor

By 2050 the world’s population is expected to increase from 7 billion to over 9 billion and nearly 70 % of the world’s population is projected to live in urban areas, exacerbating environmental and social challenges1. Currently, around half of all urban population live in cities with between 100 000–500 000 people. Cities are becoming more and more a focal point of our economies and societies at large, particulary of ongoing urbanisation. Cities need to change and develop, but this change has to be achieved in a smart way: our cities need to become Smart Cities. Smart Cities are systems of people interacting with and using flows of energy, materials, services and financing, catalysing sustainable economic development, resilience, and high quality of life; these flows and interactions become smart through making strategic use of information and communication infrastructure and services in a process of urban planning and management, which is also responsive to the social, economic and environmental needs of society. 1

Nigrad d.d. - a sustainable utiliy company Nigrad d.d. is a utility company with more than 150-years long tradition. Nigrad d.d. provides numerous public utility (communal) services such as: • maintaining waste water treatment plants, • maintaining and managing public streetlights and other lighting facilities (e.g. traffic lights, Christmas decoration, …), • maintaining public roads, roads for cyclists, pavements, parking places, city’s green areas, ... • managing central register for several municipalities, • etc.

Vision of Nigrad d.d.: to create a basis for the development of Maribor as a Smart City by merging local and global R&D capacities, cities and high-tech companies.

Nigrad d.d. has obtained several international certificates for quality of services, e.g. ISO 9001, ISO 14001, ISO 17025, showing that an emphasis is given to the quality, environmental preservation and social responsibility.

Smart City Maribor Nigrad’s existing projects initiate a number of Smart City projects with several national and international partners that actively participate by building and developing Maribor to become a pilot Smart City and further establish a smart region. Maribor is a post-industrial city with a unique geographical location in Central Europe. Therefore, Maribor could become:

• one of the world’s leading cities in the field of technologies and services for Smart Cities • a strong international Smart City development centre (test-bed), fostering innovation and international collaboration

Smart City infrastructure presents one of the most important research and development priority areas at the global level. It relates to the development of ICT, Internet of Things (IoT), Cloud Computing and analytics of Big Data. From the technological aspect a development of Smart Cities also opens and widens new areas that support innovative solutions and business models. Objectives: • develop mutually beneficial Sino-European Smart City Community, based on concrete collaboration between Maribor, Nigrad and Chinese partner cities, including high-tech companies • realize a concept of the “community of common destiny” between China and Slovenia

China and Slovenia need each other to build a bridge in their pursuit of economic, social and environmental development, where better collaboration will result in mutual benefits – Smart Cities.

Case study - Smart City Winter Service Ploughing and salting public roads 1) GPS vehicle tracking 2) GIS and mapping tools 3) Strong analytical and optimization tools 4) System maintenance and real-time inspection 5) Optimisation of driving directions and routes

Maribor case: • 41 existing ploughing and salting plans for Maribor when evaluated and optimised • In general, more than 30 % savings have been reached, by defining optimal routes • Drivers are equipped with on-board navigation systems supporting on-line optimisation of routes

Optimisation options offered by developed software: • Time to plough • Total km traveled • Number of vehicles used • Interventions cases (e.g. wrongly parked cars, break downs ...) • Refilling bases • Cost • Further optimization options

• Savings are greater combining more optimisation options (e.g. refilling bases)

Case study - A complete road audit service A development of an innovative Smart City solution for a complete road audit service by using modern navigation and software tools. Well educated team of experts and researchers ensures acquiring relevant and reliable “real-time” on-line data from the field. These data presents key information by designing and executing road re-construction, including evidences and photo material.

Modern equipment for in-situ (field) work.

Nigrad d.d. has a full (100 %) control on the whole road network situation, which ensures high quality services.

Smart Central Register for City’s Infrastructure Data model of the real world = spatial geolocation + attributes + time component Enabling: • Architecture of time determined public infrastructure network • Digital control, management and maintenance of public infrastructure (roads, public lighting, sewerage system, traffic lights, green areas, …) • Modelling of future public Smart City options Smart Green areas • Quality control, management, maintenance and design of the city’s green areas (mowing, loping, planting, etc.) • Model green areas “working events” - gathering data about the workload, resources, recycling possibilities of green material, ...

Integration of environmental issues Reducing environmental impact is one of the biggest challenges facing global society and its economy. Cities contribute an important proportion of greenhouse gas emissions and hence have a significant impact on the environment. Smart City requires also an evaluation of environmental impacts throughout the life cycle of individual sources. Thus, the integration of environmental issues in the development of Smart Cities is a key part for a successful sustainable development of urban areas.

Smart Street and Traffic Lighting Smart Street Lighting • Intelligent LED streetlights, merged into network and linked to smart grids • High level communication protocols

Smart street lighting and traffic systems have direct effects on costs and environment, ensuring

Cutting edge technology ensures:

• energy efficiency,

• automatic adaptation of lights on weather conditions

• reductions of traffic jams and flow

• control of energy costs of street lights,

• decrease of environmental impacts caused by traffic and street lights.

• monitor pollution and other environmental parameters • monitor movements of vehicles Smart Traffic System

A development of an innovative Smart City solution, ensuring and further optimizing urban mobility, including advanced devices positioned at pedestrian crossings, road intersections and other places to control the traffic flows. Investing in this Smart Traffic System includes modernisation and automation of road traffic - upgrading it in a direction to fulfil a definition of Complete Mobility. This goal can be achieved with: • smart traffic control centre • adaptive traffic control • LED signalling system • intermodal traffic management

Smart Model for Sewerage System After use, drinking water becomes a municipal wastewater and flows with industrial wastewater and rainwater into the public sewerage system. Sewerage system consists of various pipes, technological facilities such as pumping stations, dischargers, retention basins, docking facilities, inspection chambers, water treatment plants, etc. Smart model of sewerage system is based on: • ICT supported and remotely controlled facilities from the central control platform • geographical database of sewerage system and data from monitoring processes: volumetric flow rate, content of contaminated/non-contaminated water, etc. Nigrad d.d. also has an accredited research laboratory, which main activities are: • research and development in the field of wastewater • monitoring, optimisation and certification of wastewater treatment plants • expert evaluations of environmental impacts • etc.

Improved every-day decision making processes, planning, maintenance and management of sewerage system

Smart sewerage model enables: • a quick detection of malfunctions in the system (effective intervention of defects), • elimination of bottlenecks, • simulation of processes when planning new parts of the sewerage system • detection of rainwater quantity within the sewerage system • detection of excessive overflow of wastewater
