1. A traffic control system comprising:

  • a memory comprising map data having road network geometry and traffic light locations relative to intersections of the road network geometry; and

    processing circuitry configured to;

    receive signal phase and timing of traffic lights at the traffic light locations;

    receive probe and sensor data from a plurality of probes traversing the road network geometry for a plurality of past epochs;

    analyze the received probe and sensor data from the plurality of probes for the plurality of past epochs relative to the road network geometry and the traffic light locations;

    determine an epoch specific revised signal phase and timing for at least one traffic light within the road network geometry for a future epoch based on the analyzed probe and sensor data for the plurality of past epochs relative to the road network geometry and the traffic light locations;

    provide the epoch specific revised signal phase and timing to the at least one traffic light within the road network geometry; and

    cause the at least one traffic light to be controlled using the epoch specific revised signal phase and timing in response to the future epoch becoming a present epoch.
