Abstract: A location specifying apparatus comprises a first circuit and a second circuit. The first circuit is configured to store information regarding a predetermined feature including location information of the predetermined feature, information regarding a position of a specific point on a road, and information indicating a correlation of the information regarding the predetermined feature to the information regarding the position of the specific point on the road. The second circuit is configured to obtain image data ahead of a moving body; to identify a location of the predetermined feature in an image expressed by the image data, based on the information regarding the position of the specific point on the road, the information indicating the correlation, and the information regarding the predetermined feature; and to specify the location of the moving body, based on the identified location of the predetermined feature.

Abstract: A route search apparatus comprises a road information storage part configured to store road information including link information comprised of single link information and composite link information; and a route searcher configured to search a recommended route between two different points using the link information. The single link information includes information regarding an approach link that is a link approaching to a node at one end of a target link, an exit link that is a link exiting from a node at the other end of the target link, and a cost of the target link for entering from the approach link and exiting to the exit link. The composite link information includes information regarding an approach link that is a link approaching to a node at one end of a target link array, an exit link that is a link exiting from a node at the other end of the target link array, and a cost of the target link array for entering from the approach link and exiting to the exit link.
