Intelligent Traffic Light System for Emergency Vehicle

Abstract

In this project we introduce an intelligent system that controls the traffic lights, to help emergency vehicles such as ambulance , fire engine, police cars etc… to reach the place they need in due course and without any late, so drivers that have emergency case will not spend unnecessary time waiting for the traffic lights to change, because the system will give them the priority to have the green light. Zigbee technology will be used as wireless communication, a transmitter on the emergency vehicle side and a receiver on the traffic light side. If there is an emergency case, the system will be triggered and xbee receivers will be ready to receive signal from emergency car transmitter. Then signal will be sent to the central xbee reciver which will pass it to the traffic lights microcontroller that will change the normal behavior of the traffic lights by setting the desired one as green and the others as red.
