Abstract
The present invention provides a vehicle guidance system capable of showing a recommendable route between the present position of the vehicle and a destination on a map. The vehicle guidance system comprises a routing unit for finding a recommendable route between the present position of the vehicle and a destination by using road data, a congestion detecting unit detects traffic congestion on the basis of the traveling mode of the vehicle, and a congested place estimating unit estimates presumably congested roads on the recommendable route by using the road data when the congestion detecting unit detects traffic congestion.
