Abstract
Travel guidance systems, devices, methods, and programs set a route from a departure point toward destination and acquire a position of a movable body along the route. The guidance systems, devices, methods, and programs determine whether the movable body has arrived at the destination by acquiring a distance from an end of the set route to the destination. When the acquired distance is less than a predetermined distance, the determination is based on the end of the route. When the acquired distance is equal to or more than the predetermined distance and the destination is a specific point, the determination is based on the end of the route. When the acquired distance is equal to or more than the predetermined distance and the destination is a point that is not a specific point, the determination is based on a position of the destination.
