ABSTRACT:
A route search apparatus according to the present invention comprises: a storage device that stores link positional information of individual links and link connection information between the links, a minimum unit of road on a map being referred to as a link; a departure point specification device that specifies a point of departure on the map; a destination specification device that specifies a destination on the map; and a control device that selects a start point link that is to constitute a start point of a route search based upon the point of departure specified by the departure point specification device and the link positional information, selects an end point link that is to constitute an end point of the route search based upon the destination specified by the destination specification device and the link positional information, and performs a route search between the start point link and the end point link based upon the link connection information. And the control device selects a plurality of the start point links and a plurality of the end point links.
