Siemens controls traffic in Poznan

- Munich, Germany, EU
Intelligent traffic control system to reduce congestion and enhance attractiveness of public transportation

Passenger information system informs about transit time, fastest route and available parking space

Priority regulation for public transportation

Siemens is supplying an intelligent transportation system for the city of Poznan in Poland. The company won a corresponding contract from the Poznan transportation authority ZDM (Zarząd Dróg Miejskich w Poznaniu). The main goal is to synchronize private and public transportation in a cross-system concept in order to optimize the overall traffic situation in the city. The order is worth about EUR 15 million. Commissioning of the system is scheduled for spring 2015.

To improve the traffic situation in the Polish city of Poznan, real-time traffic data from more than 200 measurement points, such as intersections, parking lots and public transportation, will be collected in the traffic management center, evaluated and processed using Sitraffic Concert.

The Siemens system will provide information on the current traffic situation, available parking spaces and the departure times of nearby public transportation. Where required, traffic light control will be influenced to speed up the flow of public transport. More than 85 information panels at the bus and tram stations will indicate the current information on relevant vehicles arrival times. All traffic information will be also forwarded to the Internet and enabled for radio stations, texting and email services.

Along the roads at strategic locations 12 variable message signs (VMS) will be mounted to provide important information for drivers. To do this, the traffic control center collects the data from 115 intersections in the main road network and measure the type, number and speed of passing vehicles at short intervals. In addition, the data will be also made available to all transportation applications, for instance to compare travel times between public and private transportation.

With a population of over 500,000, Poznan is the fifth largest city in Poland and a center of industry, commerce and research. Since the transition to a market economy, traffic in Poznan has been growing rapidly. The authorities therefore decided to introduce an intelligent transportation system and implement the most innovative solutions to support further transport-related developments and increase the efficiency of public transportation.
