Along with the progress of advanced technologies, authorities try to provide travelers with reasonable and accurate route guidance information and to increase the efficiency of transportation system via Advanced Traveler Information Systems (ATIS). Therefore, the main purpose of this research is to analyze the effects of traffic incident on route diversion through the provision of guiding information. This research adopts the simulation tool of traffic assignment (DYNASMART-P), to analyze guiding vehicles into the proper routes. According to certain schedule, the routes had been assigned before those vehicles start to the destination. Vehicles can be observed while accidents happen. DYNASMART-P provides routing information by means of Variable Message Signs (VMS). The effects of VMS’s guidance information on drivers can be evaluated by measuring drivers' route choice behaviors. This research takes the highway network of western part Taiwan as example. Different conditions, such as various damand levels, route taking, positions of VMS set, and the probability of obeying guidance information can be discussed on the effects of traffic accidents and VMS affect drivers’ route choice behaviors. These results lead to the conclusion that the VMS guidance information for a long trip should be disseminated one to two entrances upstream of the location of incident. The result also shows that there is no significant effect of the provision of early travel time saving information.
