摘要： Vehicle-position-recognition apparatuses, methods, and programs acquire current position information indicating a current position of a vehicle and acquire road information indicating at least one road based on a connection relationship between plural links. The apparatuses, methods, and programs determine a link where the vehicle travels based on the current position information and the road information and generate travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link. The apparatuses, methods, and programs acquire an image of an area surrounding the vehicle, recognize a recognition target in the acquired image, and store the generated travel-history information in the memory in association with information indicating the recognition of the recognition target. The apparatuses, methods, and programs generate learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information usable to determine on which of the links branched out at the branch point that the vehicle is traveling.
