Traffic flow improving system for vehicle i.e. car, has road network divided into road sections, where alternate remainder route with expected shortest remainder route travel time is determined and indicated in vehicle

摘要

The system has a road network (1) divided into road sections. A server (5) detects current expected road section travel time from information sent by seizing vehicles under consideration of respective age of the information for each traveled road section. The information on the current expected road section travel time is sent to the server by a sender for road section (3) of the network. An alternate remainder route with expected shortest remainder route travel time is determined and indicated in a vehicle (2) based on current expected road section travel time to a current remainder route. An independent claim is also included for a device for a navigation system of a vehicle.
