Abstract

A method is provided for controlling traffic lights of a road geometry network using a cloud-based traffic control system. Methods may include: receiving map data including road network geometry and traffic light locations relative to intersections of the road network geometry; receiving signal phase and timing of traffic lights at the traffic light locations; receiving probe and sensor data from a plurality of probes traversing the road network geometry; analyzing the received probe and sensor data from the plurality of probes relative to the road network geometry and the traffic light locations; determining revised signal phase and timing for at least one traffic light within the road network geometry based on the analyzed probe and sensor data relative to the road network geometry and the traffic light locations; and providing revised signal phase and timing to the at least one traffic light within the road network geometry.
