There are a growing number of 'floating vehicles', or probes, that are used as mobile sensors to collect up-to-date traffic data across the entire road network. In the UK, GPS based floating vehicle data records collectedfrom large equipped fleets of commercial vehicles, is being used to assess journey times, speeds and congestion across the strategic and urban roadnetworks. In the future, data from factory installed in-vehicle sensors and Advanced Driver Assist Systems is likely to spur further development ofdynamic traffic monitoring capabilities, particularly in the study of driver behaviour and the evaluation of Intelligent Transport Systems. This paper aims to review floating vehicle data sources and based on results froma case study, considers the potential use of dynamic traffic information to improve the calibration and validation of traffic microsimulation models.
