This system used three stage intelligent traffic station subsystems to forecast the path on which vehicle will go. First stage subsystem can forecast road node which adjacented to traffic station. Second stage subsystem was designed for bigger area, for example city, the third stage subsystem was for the larger area between city. Second stage subsystem system used A* based on orientation to calculate shortest path, third stage subsystem calculated critical node of a large area. The system can compose dispersed monitor information, forecast vehicle path, dynamic analysis, hierarchical monitor .It played an important role in ITS.
