Pollution and fuel consumption in automobiles is becoming a matter of grave concern. It is essential to build an efficient and much more reliable system that would control this issue in traffic signals. The objective of this project is to introduce a system, which would detect the status of the traffic signal and control the engine ignition automatically thereby reducing the fuel consumption and reducing pollution. Radio frequency modules, interfaced with micro controller are used to transmit the signals from traffic light and detect them by the automobiles.
