Necessary Penetration Rates of Probe Vehicles

Demands made on the quality of traffic information are increasing due to high road network utilization. The successful operation of traffic information systems requires acquisition of up-to-date and reliable data. This prerequisite is not satisfactorily met throughout wide areas of the traffic network. Often, road traffic incidents are detected too late and are poorly localized in space and time. The need to ensure the quality of traffic telematics services has thus led BMW Research to search for new methods of improving network-wide traffic data acquisition. Efforts have focused on the “floating car” approach, in which suitably equipped probe vehicles serve as mobile sensors. This article considers the potential of vehicle generated traffic data acquisition for generation of traffic information and local hazard warnings. A method for estimating the required floating car penetration rates on the basis of traffic volume and arrival probabilities is presented.
