An IVHS (Intelligent Vehicle Highway System) navigation system obtains information from road sensors, city maps and event schedules, and generates information for drivers. We address two aspects of navigation in IVHS: finding a path and evaluating a given path. Finding a path between a starting point and the destination is based on heuristic search procedures. Evaluation of a given path is modeled as a path query. We use a new access method, called MoBiLe File[18], for efficient map storage and access. We propose a hierarchical path planning algorithm which is capable of finding optimal paths while avoiding obstacles. We contribute obstacle avoidance heuristics for faster computation of paths between two points.
