Route guidance system using fuzzy information

In this paper, a set of models for a route guidance system is proposed. The models treat the driver perceived travel time estimate as a fuzzy number. The best path is determined by comparing the fuzzy travel times on alternative paths. In this process, the driver's bias can be incorporated. The bias may be considered as the driver's propensity towards risk taking or risk averting. Thus, it can be adapted to individual driver's personality if installed on board a vehicle.
