Abstract
A traffic jam detection system and method to estimate a traffic jam condition ahead of a vehicle. When a vehicle arrives at the tail end of a traffic jam, information is related to the tail end of the traffic jam is transmitted to an information center. The information center collects this information related to plural traffic jams from on-vehicle information terminals of a number of vehicles and develops estimated tail end information for each of the traffic jams. The information center transmits the estimated tail end information to vehicles approaching traffic jams for the driver to determine whether a traffic jam should be avoided or not.
