Adaptive route guidance system with real-time traffic information

This paper presents a systematic approach to adaptively realize the vehicle routing with the real-time traffic information during the whole time period of a day. It focuses on the route planning procedures for determining the optimal route based on analytical hierarchy process (AHP) and fuzzy logic theory. This approach can adaptively switch from pre-routing to real-time routing based on real-time traffic information to find an optimal route for each O-D (Origin-Destination) pairs. The AHP-FUZZY approach is a multi-criteria combination system, which can greatly simplify the definition of decision strategy and represent the multiple criteria explicitly. A simulation is implemented to compare with the traditional route guidance system and the results are validated.
