The system provides a wireless communication between the traffic light and the emergency vehicle using radio signals. The system consists of a number of sensing devices. Each device comprises of a transceiver whose working is controlled by a microcontroller. Each of these devices is placed at light poles, towards the traffic signal from all the sides. The emergency vehicle and the traffic light itself is equipped with a similar sensing device. When an emergency vehicle approaches the crossing, the radio signals are transmitted from it to every sensor mounted on the light poles one after the other. When the sensing device nearest to the traffic light finally receives the signal from its preceding pole, the traffic light changes to green. This facilitates the smooth and quick passage of the emergency vehicle. The traffic light follows its default pattern once the vehicle crosses it and reaches the nearest pole sensor on the other side of the signal.
