Abstract:
A navigation device includes a travel road specification portion acquiring a current location of a vehicle and specifying a travel road actually traveled by the vehicle, a continuity determination portion determining an existence of a continuity between the travel road and a first road connected to an end point of the travel road, and an extension road designation portion. The end point of the travel road is defined as a reference end point, the travel road is defined as a reference road, and the first road is defined as a determination target road. The extension road designation portion designates the first road as a first extension road when the continuity determination portion determines that the continuity exists between the first road and the travel road.
