Abstract:
A route searching section 33 determines whether the area of the current position is an urban area or a suburban area, sets a predetermined area S or a predetermined time Deltat responsive to the determination result, and determines the presence or absence of restriction on each time restriction road depending on whether or not a time restriction road exists in the predetermined area S centering around the current position and whether or not the restriction time period of the time restriction road overlaps the time period in the predetermined time Deltat from the current time to. If the route searching section determines the presence of restriction, it searches for a route avoiding the time restriction road.
