Abstract
Traffic information, including traffic flow information and traffic incident information, obtained through a traffic management system for providing and facilitating the exchange of traffic information between a remote location and a vehicle may be presented to a user on a user display in the vehicle. In one embodiment, traffic information provided to a vehicle navigation device is refined by comparing the average speed of the vehicle against the average speed of other vehicles traveling along the same road. In another embodiment, the operation of a traffic signal is controlled based, in part, on the current traffic flow and distance from the traffic signal to alleviate traffic congestion.
