A system and method for self-optimizing traffic flow using shared vehicle information that utilizes multiple controllers in dynamic communication to optimize the flow of traffic. The system and method utilizes one or more traffic synchronization controllers (TSCs) (receivers) that receive information from one or more vehicle based transmitters called vehicle information agents (VIAs) and/or a network of traffic control devices (TCDs) associated with the traffic synchronization controllers to determine a variety of information related to traffic within a geographic region, including volume, speed, destination, intended route of the vehicle, as well as other vehicle related information, in order to determine the optimal flow of traffic within the region. The system and method then transmits traffic control signals to the various traffic control devices within the region or adjacent regions in order to optimally control the flow of traffic. The system and method may also share information amongst traffic synchronization controllers within the network in order to optimize the flow of traffic over a larger region.
