ABSTRACT:
A car mounted navigation system uses map data of polygons defined by roads of a predetermined rank or more of significance, connects a starting polygon containing a starting point to a destination polygon containing a destination with a chain of polygons adjoining at common sides of each pair of adjoining polygons and arranged between the starting and destination polygons to compute a plurality of routes extending from the starting point to the destination polygon, each route including a combination of sides of the chain polygons, the starting polygon and the destination polygon. A car operator selects an appropriate route from the computed routes. The system requires neither need for a great amount of database-made map data nor need for an entry of map data with a digitizer.
