Energy-Efficient Vehicle and/or Traffic Light Control

Systems and methods for controlling traffic flow on road(s). The methods comprise: obtaining, by a processor, traffic related information comprising a total number of vehicles that caused an activation of a sensor of a first detector located at a first intersection of a plurality of intersections; generating, by the processor, a predicted traffic volume at one or more downstream second intersections based on the traffic related information; generating, by the processor, a traffic light timing for at least two next cycles based on the predicted traffic volume; and controlling, by the processor, a traffic light of the one or more downstream second intersections in accordance with the traffic light timing to reduce a probability or likelihood that the vehicle will stop at a red light thereat.
