A traffic control system includes at least one traffic control device 14 for outputting signals to control flow of traffic, the traffic control device includes a traffic lightsignal unit 3a-d. A control means 8 receives traffic data, possibly wirelessly via a modem 5, relating to traffic flow representing position and/or movement data for a plurality of vehicles. The traffic control device controls the timing of red, amber and/or green signals output depending on the traffic flow data which is at least partly from a remote source such as a server 20 or possibly from vehicles via wireless connection. The remote source may be a traffic management agency, satellite navigation service provider or a broadcaster. Further data sources may be sensor based such as a microwave sensor, a below ground sensor or a camera where the video output from the camera may be used in the processing of video analytics.
