PROBE VEHICLE BASED ESTIMATION OF PARAMETERS FOR ADAPTING TRAFFIC SIGNAL CONTROL AT SINGLE INTERSECTIONS

摘要

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