Our colleagues Norbert Varga and László Bokor together with András Takács, József Kovács and László Virág from Commsignia Ltd. have presented their results on V2X communication-centric traffic light controller systems during the 15th International Conference on ITS Telecommunications (ITST) in Warsaw, Poland. The presented work (available on ieeexplore) focuses on advanced traffic light / traffic signal controller systems which will play an important role in adaptively and dynamically coordinating individual traffic lights of near future smart cities to manage city-wide objectives of traffic operations using vehicle-to-vehicle (V2V) and vehicle-to- infrastructure (V2I) communication techniques (together referred as V2X). Dynamic real-time information exchange between all the players of the traffic controlling ecosystem and fostering cooperative urban mobility are the main goals of the proposed architecture while the presented testbed showcases the authors’ proof-of-concept implementation of the proposed scheme.
