Cooperative Traffic Signals Under Adaptive UTC

This paper presents details of a demonstration project that was jointly undertaken between Traffic for London (TfL), BMW and ITIS Holdings (now INRIX). The project’s aim was to explore the possibility of providing in-vehicle traffic light information to drivers approaching traffic signals, advising them of the changes the traffic signals are about to make. This would allow drivers to make informed driving decisions, thereby smoothing traffic flow and reducing carbon dioxide (CO2) emissions. The main aim of the trial was to investigate is the ability to send traffic light information in real time from TfL’s UTC1 SCOOT system to the vehicle. Although this may appear relatively straight forward, providing accurate traffic signal data into vehicles in real time on such a system is particularly challenging. SCOOT is a dynamic system whereby the traffic signal timing is adaptive depending on traffic conditions. The timing and accuracy of data delivery were important aspects of this trial.
