1. Smart City Maribor

2. 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 on-
going 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.

4. • 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 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:
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.
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.
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

6. 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
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
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
• Savings are greater combining more
optimisation options (e.g. refilling bases)

7. 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.
Nigrad d.d. has a full (100 %) control on
the whole road network situation, which
ensures high quality services.
Modern equipment for in-situ (field) work.

8. 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.

9. Smart Street and Traffic Lighting
Smart Street Lighting
• Intelligent LED streetlights, merged into network and linked to smart grids
• High level communication protocols
Cutting edge technology ensures:
• automatic adaptation of lights on weather conditions
• control of energy costs of 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 street lighting and traffic systems have
direct effects on costs and environment,
ensuring
• energy efficiency,
• reductions of traffic jams and flow
• decrease of environmental impacts caused
by traffic and street lights.

10. 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.
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
Improved every-day decision making
processes, planning, maintenance and
management of sewerage system
