QUICK ROUTE-FINDING ALGORITHM

Takeshi Yagyu; Makoto Fushimi; Yoshiki Ueyama; Shigetoshi Azuma

A quick route-finding algorithm was developed for determining the optimal route between two points. Also, a new method for recording on a CD-ROM, using a computer, optimal routes between all major points, was created. The on-board system accesses the CD-ROM data to find the route. This method greatly reduces the time needed to find a route.
