ITS research project "BiDiMoVe" connects busses and traffic lights intelligently along metro bus line 26 in Hamburg Rahlstedt

On 24.09.2021, the results from the Hamburg ITS research project "BiDiMoVe" (stands for "Bidirectional, Multimodal, Networked") were successfully demonstrated to Dr. Anjes Tjarks, Senator for Transport and Mobility Transition of the Free and Hanseatic City of Hamburg, Claudia Güsken, Chief Human Resources Officer of Hamburger Hochbahn AG, Dr. Stefan Klotz, Managing Director of Landesbetrieb Straßen, Brücken und Gewässer and various members of the press.


Public transport is an important part of the mobility transition in Hamburg. The goal is to continue to sustainably increase the service, punctuality and comfort for passengers. This is precisely where the BiDiMoVe project comes in: On a section of the Metrobus line M26 in Rahlstedt, a new type of communication technology has been installed in the buses operating there. In addition, nine traffic lights along the route between Rahlstedt station and "Am Luisenhof" in Farmsen are equipped with the modern technology. The systems in the busses and at the traffic lights can communicate with each other and thus ensure bus-optimised traffic light control, increased punctuality and more adherence to the timetable. The bus drivers receive recommendations on the optimal speeds to be driven. In this way, a demand-oriented prioritisation of public transport on an important tangential connection in the north-eastern bus network of the outer city is being tested in the sense of the mobility turnaround and the targeted Hamburg Takt. In addition, the system makes it possible to give the bus driver warning signals directly into the cockpit when turning in order to be able to react to cyclists and scooter riders travelling in parallel. A special thermographic camera is used at intersections where the bus crosses the bicycle traffic. This camera detects cyclists based on their infrared radiation as a difference to the ambient temperature and sends the system information directly about the cyclist's direction of travel and speed. In the bus, this information is linked to the bus's travel data and evaluated. As soon as a collision between bus and cyclist is imminent, a warning message is displayed in the A-column of the bus and in the instrument cluster.


In summary, the BiDiMoVe project set up a modern public key infrastructure (PKI), which ensures the IT security of the system. In addition, a functioning complete system has been rolled out as a prototype on the metro bus line 26 of Hamburger Hochbahn AG. This brings BiDiMoVe remarkably close to productive use and at the same time shows the potential of connectivity technology.


Interested parties can also experience the BiDiMoVe demonstrator live at the ITS World Congress 2021 in Hamburg. Register now for the free Public Day on 14.10.2021:
