Abstract
In a navigation system a driver of a vehicle is guided along a planned route (310) from an origin to a destination. The system comprises a receiver (122) for receiving a traffic message of an actual travel condition concerning a road-element. The system comprises an evaluation module (126) to determine whether the received traffic message makes it necessary to plan a new route to the destination. If a traffic message is received for a road-element which does not form a part of the planned route (212), the evaluation module determines whether the message indicates an improvement (204) of the travel condition of that road-element and if this is so then the planning module plans a new route.
