Route guidance systems, methods, and programs detect a current position of a vehicle and search for a route to a destination based on the detected current position. The systems, methods, and programs identify a guide intersection along the route and set a route guide point at a predetermined point on the route before the guide intersection. The systems, methods, and programs calculate a number of intersections along the route from the route guide point to the guide intersection having both a traffic signal and a road feature and perform a voice output based on the calculated number of intersections when the vehicle arrives at the route guide point.
