Preliminary Analysis of the Application of Taxi Probe Vehicles for Travel Time Record in Bangkok

Travel information especially travel time data is needed for modern traffic management and traveler information dissemination. Real-time travel time data can be obtained from several sources and data collection methods; however, reliability and cost-effectiveness of data is requires special examination. global positioning system (GPS)-based Probe Car data collection method potentially offers efficient way in collecting large amount of reliable data with minimal investment, since it requires little investment on roadside infrastructure and is capable of receiving large amount of data, temporally and spatially. Many past studies have shown that taxis are suitable to be used as the Probe vehicle. However, the resulting travel time data are conditional on characteristics of probe vehicles and accuracy (and reliability) of GPS data. This research is the investigation of data collected from GPS receiver installed on taxis in Bangkok. The purposes of this study are to investigate taxi driving pattern, to examine the availability and reliability of data collected by GPS, and to demonstrate the potential of using these GPS equipped taxis as probe vehicles for travel time collection in Bangkok. Data was collected from 5 taxis operating regularly for the period of 30 days.
