• The purposes of this study were to investigate accuracy and reliability of travel time information and to assess the effectiveness of probe vehicle in providing travel time information under various traffic conditions. Paramics V5 was used to generate travel time data on a hypothetical network. Average travel time on links and routes were analyzed for various percentages of probe vehicles and compared to the 'true' average travel time using 'bootstrapping' technique. Results indicate that the plots of probe vehicle average travel time versus 'true' average travel time for link and route case agreed well. However, travel time from probe vehicles is less accurate when traffic is congested. A case study was carried out to consider travel time between Origin-Destination. The quality of travel time not only depends on the percentage of probes but also the traffic conditions.
