Düsseldorf advances CAV testing

Siemens Mobility is providing intelligent mobility technology for near-real-time exchange of information between vehicles and infrastructure

The city of Düsseldorf is preparing itself for the future of mobility

The German city of Düsseldorf has opened an automated and connected vehicle test track in conjunction with Siemens.


Equipped with Siemens Mobility technology, the 20km digital test field highlights the latest intelligent traffic technologies, which is preparing the region for automated and autonomous traffic of the future.


Preparing for future mobility


"We are proud to be a partner with the City of Düsseldorf on this important project, which is laying the ground work for the future of road mobility in Germany,” said Manfred Fuhg, head of Siemens Mobility in Germany.


“The test track is the first of its kind in Germany and our technologies will reduce traffic congestion, enhance safety and provide more availability of mass transit as we continue to move towards vehicle autonomy."


The project has four key Siemens Mobility components:

  • road side units (RSU): the communication units allow for near-real-time information exchange between vehicles and infrastructure. These safety-critical network elements are installed and located at each of the four intersections with a signal
  • an integrated SPAT (signal phase and timing) unit: this forecasts green and red-light timing and transmits via RSU to vehicles
  • vehicle on-board units: these are used for vehicle-to-infrastructure communication. In the test field, these systems are used for public transport signal prioritisation with 16 Rheinbahn buses. This car-to-X (C2X) technology is the first of its kind in Germany
  • satellite positioning: the Rheinbahn vehicles are also equipped with this to test public transport privileges (such as right of way and designated lanes). When implemented in connected vehicle traffic settings, these technologies reduce traffic congestion, help improve safety and reduce environmental impact of traffic emissions.
