Abstract
A smart traffic control device transmits information to approaching vehicles regarding its current and future state enabling vehicles to control their speed to avoid arriving at the traffic control device until it permits the passage of traffic, thus avoiding stopping, idling and reaccelerating when reaching the traffic control device. In other embodiments the traffic control device or systems receives information from vehicles, transmitting it to other vehicles.
