Claims

[Scope of utility model registration request]

For a vehicle configured to obtain a vehicle course based on road network data from a map data storage means, current position data from a position calculation means, and departure point and destination point data from an input means and display the guide on a display means. In a route guidance device, means for determining whether or not to avoid a predicted congested point based on the predicted traffic jam starting time of the predicted future congested point and the predicted arrival time to that point based on traffic congestion information and statistical transition data. A route guidance device for a vehicle, characterized in that it is provided with.
