ABSTRACT:
A navigation system that searches for a route to a destination based on stored map data and provides navigation guidance to the destination along the route includes a controller that acquires road congestion information associated with the route, searches for the route to the destination based on a calculated search cost and changes a search cost based on predicted secondary congestion that is predicted based on acquired road congestion information, wherein a recommendable route that can avoid congestion is searched based on the search cost that has been changed based on the predicted secondary congestion.
