Abstract
Route costs are computed using the Dijkstra algorithm based on link information and connection information and a destination route is set based on a connection of links which has the least route cost. The route cost is set to sub-nodes of each connection link. Therefore, optimal routes can be set even though traffic regulations such as no right turns or the like exist on certain nodes.
