METHODS AND SYSTEMS FOR ADAPTIVE TRAFFIC CONTROL

Traffic control systems, signal control systems, and methods of using such systems are disclosed. A real-time adaptive traffic control system includes multiple signal control systems, each associated with a signalized intersection. Each signal control system includes a receiver, a processor, and a transmitter. The receiver receives inflow traffic control information from other signal control systems and information associated with one or more vehicles or devices. The processor generates a signal timing plan based on the information and the inflow traffic control information. The transmitter transmits outflow traffic control information to other signal control systems. A fee or toll may be incurred for receiving the route information associated with a vehicle or device. The result of providing such route information may be better traffic flow for the transmitting vehicle or device and other vehicles or devices resulting from improved information being available to the traffic control system.
