Intelligent Transport System - ITS

Zarządzanie ruchem i transportem publicznym Traffic and public transport management

ITS system allows efficient traffic and public transport management, improvement of traffic conditions for vehicles and other road users, applying priority to public transport, informing passengers about available means of public transport, informing drivers about current traffic conditions, planning, and development of transport infrastructure thanks to having rich analytical material.

Traffic control consists of centrally managing the operation of traffic lights to achieve traffic flow during changing conditions in and out of peak hours. The system allows priority to be given to public transport vehicles, allowing them to pass through the intersection smoothly without stopping. Traffic data from hundreds of detectors is analyzed and the calculated operating parameters are transmitted back to the light signal controllers. The process of introducing changes in the field is carried out in real time. Traffic analysis is carried out by means of advanced mathematical algorithms.


System applications
  • Efficient traffic and public transport management

  • Improving travel conditions for vehicles and other road users

  • Applying priority to public transport

  • Informing passengers about available means of public transport to reach their destination using electronic information media

  • Informing drivers about current traffic conditions with electronic information media

  • Transportation infrastructure planning and development by having a rich analytical material

Characteristics of the ITS system

The main modules of the system

Dynamic bus stop information is based on displaying scheduled and forecasted arrival times of buses and streetcars on electronic variable message boards.
These boards are installed at public transport stops.

Variable Message Signs, so called VMS, are used to inform drivers about the road situation related to repairs, detours, as well as to provide current traffic parameters, i.e., travel time for specific directions, permissible speed limit, roadway icing, weather conditions, etc. The boards are installed over the main traffic arteries. The information presented comes from a variety of sources, such as cameras, weather stations, vehicle weigh stations, and the Traffic Management Center.

Intersection monitoring and traffic event detection is based on digital cameras installed within traffic junctions. The cameras enable the operators working in the Traffic Management Center to observe vehicle streams and analyze traffic volume variations in a visual manner.

Pre-selective weighing points are used for obtaining detailed parameters concerning road traffic. Their main task is to measure the weight of the moving vehicles in order to protect the surface of public roads, as well as to measure the height of the vehicle in order to protect urban infrastructure, which in conjunction with the possibility of reading the registration number of the vehicle allows for enforcement of offenses.

The Public Transport Supervision System is responsible for collecting data on the available transport infrastructure. It supports dispatchers in managing used rolling stock (streetcars, buses, etc.) so that any failures or traffic incidents have the least possible impact on the quality of service.

Infrastructure monitoring is responsible for transmitting information about all failures of key devices installed in the operating area of the entire system. When a failure is detected, the application sends a notification to the appropriate technical services responsible for restoring efficiency. The system operator can determine the exact location of the faulty device on a city map.

The monitoring of red light running allows the detection of offenses committed by drivers violating traffic regulations at intersections controlled by traffic lights.
The system prepares evidence (photos and video) which allows to initiate a fine procedure.

Traffic Management Center – a unit that coordinates operational activities to supervise and improve traffic flow. Activities undertaken in the CZR: – processing and analysis of data coming from traffic detectors, induction loops, video cameras, traffic light controllers, radars; – Collecting data on the city’s traffic, public transportation, and parking situation; – Creating analyses and reports for ongoing traffic management and transport infrastructure development; – Management of infrastructure built for traffic engineering purposes.
