Probe Vehicle Based Estimation of Parameters for Adapting Traffic Signal Control at Single Intersections

Signalized intersections essentially impair the quality of traffic flow particularly in urban regions. An effective control of traffic lights on the one hand and an increasingly efficient road traffic flow as a result of more information for drivers on the other hand are the basic principles for a good symbiosis. Other than conventional detectors, the so-called co-operative systems in transport offer the opportunity for an extensive collection of detailed information on traffic conditions via floating car data in order to optimize the control of traffic lights. The paper focuses on the advantages of using floating car data (FCD) for the possibility to capture signalization quality parameters directly, and integrate them into the signal controller. Therefore the correlation between the mobile collected data will be identified.
