1. A signaling system, comprising;

  • a traffic signal controller adapted to couple to a traffic control indicator, the traffic signal controller adapted to control different states of the traffic control indicator;

    a signal state information module having a state of a traffic control indicator;

    an RF transmitter operable to transmit signals toward at least one object/vehicle target;

    an RF receiver operable to receive reflected signals from at least one said object/vehicle target; and

    a radar/traffic processor coupled to the traffic signal controller and the signal state information module, and adapted to receive signals from the RF receiver;

    the radar/traffic processor having an algorithm operable to determine characteristics of the object/vehicle targets and dynamically cause the traffic signal controller to control a state of the traffic control indicator in response thereto.
