A number of ladar sensors, visible cameras, and traffic signal lights are mounted within a traffic control zone, and a local traffic controller is provided to ensure safety and provide optimum traffic flow for vehicular and pedestrian traffic by combining the inputs from the ladar sensors and visible cameras and detecting the type of traffic, the intended path, and then controlling the signal lights dynamically. The local traffic controller also maintains a local traffic database, and communicates via duplex radio link with similarly equipped vehicles to effect an additional control capability. A regional traffic controller communicates with the local traffic controller to provide control and optimal traffic flow within a district control zone, and maintains a district traffic database.
