Abstract
Abstract A vehicle navigation system ( 100 ) comprises a planning module ( 110 ) for planning a route between an origin and a destination and subsequently guides the driver along the planned route. The system further comprises a receiver ( 124 ) for the reception of traffic messages related to problem locations on roads, which messages are transferred to the driver. The navigation system according to the invention is arranged to read from its storage medium ( 106 ) with the map database additional information ( 404 ) indicating the potential problem locations for roads in the database. In this way, the information from the traffic message can be combined with the information from the map database and further exploited in the system, e.g. for planning a new route.
