Abstract
Route guidance for vehicle navigation in which a destination in a category of places is searched for and guidance along a suitable guide route to the destination is performed. If the user's original purpose cannot be achieved even after reaching the destination, another destination in the same category of places is automatically searched for and guidance to the new destination is performed along a suitable guide route. If e.g. the category is convenience stores, then convenience stores within a certain range of the user's vehicle position are searched to find the nearest destination. A guide route to the destination is found (excluding congested roads or roads under traffic control on the basis of road traffic information obtained e.g. from ATIS). If the vehicle moves out of a certain range of the destination without stopping longer than a certain time period after entering within the range, another destination in the same category of places is automatically searched for and the vehicle is guided along a suitable route to the new destination.
