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

Abstract

Dynamic traffic assignment tools have been attracting increasing attention with the progress of traffic management policies based on information technology. These dynamic 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 behaviors using probe-vehicle data The results of analyses show that route choice behaviors relate to the distance from driver's position to the destination and that dynamic route choice behaviors are modeled better by considering decision process during trips.
