Dynamic route guidance systems are expected to achieve smooth and safety traffic and improve road traffic environment. It needs to prepare a prediction model of traffic condition, in which driver's route choice behavior is explicitly involved. Dynamic traffic assignment models have been studied for describing road network flow, however, road transport informatics(RTI)such as route guidance systems are not considered in those models. This paper shows the relation between network assignment models and RTI in order to identify the roles of traffic assignment models for constructing dynamic route guidance systems and to discuss necessity conditions for model development.
