Intelligent Traffic Light for Emergency Vehicles Clearance

Human life is a serious matter, so we should not neglect anything that might threaten it. It must be protected in all possible ways. Consequently, all health services such as hospitals, medicines, ambulances and so on need to evolve continuously to overcome life-threatening problems. Since many people could lose their life because of an ambulance delay. We proposed a system that provides a way to overcome the ambulance delay problem. With the current traffic light system, the ambulance can get stuck in the traffic or may cause an accident while it crosses the red light. To avoid that, the proposed system enables the ambulance to control the traffic light. When comparing the estimated time required for an emergency vehicle to move from location A to location B while passing two traffic lights, it would take 10 minutes with the current traffic light system based on the GPS assuming no traffic delay. While with the proposed system, it would take 8 min to pass the same distance. So the difference is 1 min for each traffic light on the way. Thus, the system will facilitate the emergency vehicle movement to save people's life. The hardware used to implement this project includes Arduino UNO and mega with network shield (ZigBee).
