Preliminary Analysis on Dynamic Route Choice Behavior Using Probe-Vehicle Data

Dynamic traffic assignment models have been attracting increasing attention with the progress of traffic management policies based on information technology. These dynamic estimation tools, however, just apply static route choice models either at only origin node or at every arrival node. This paper aims at providing some knowledge on drivers’ dynamic route choice behavior using probe-vehicle data. The results of analyses show that route choice behavior relates to the distance from driver’s position to the destination and that dynamic route choice behavior is modeled better by considering decision process during the trip.
