SMART TRAFFIC LIGHT WITH IOT

Abstract

Traffic lights are signaling devices position at road intersections to control flows of traffic. Due to the Penang is very small, and there is a lot of road with junction, traffic light become the most important devices to control the traffic flows. The existing traffic light system is the pre-set period, inflexibility of the traffic light has sometimes caused the traffic to be jammed. It causes a lot of troubles to the drivers and it greatly affects those emergency especially for ambulance. This paper presented a model of smart traffic light system was built by using sensors to detect the traffic flow and response accordingly. The system is able to arrange the logic to prioritize the directions with more traffics. With this smart traffic light algorithm, it will make the traffic light more efficient and reduce the traffic jam. A mobile application was created together with the system which able to send interrupt to the traffic light system by using Internet of Thing. The traffic light will change to green for the direction where the emergency rescue team come from. This can help to make emergency rescue team to pass through the traffic light with minimum delay. The proposed model expected to provide a significant improvement to the traffic system in Penang.
