Smart autonomous traffic light switching by traffic density measurement through sensors

Traffic light control is one of the serious technical hazards of the urban areas in almost every country around the world. This is due to rapid increase in number of vehicles. In order to reduce the time and complexity, a system that has to be combine the existing technology with artificial intelligence to think themselves. This newly developed project will enable the traffic light to switch from red to green based on traffic density. This paper is concerned with the development and implementation of Sensor based Traffic Light System with Dynamic Control which in turn reduces the Average Trip Waiting Time (ATWT). It consists of IR sensors, Low Power embedded controllers, comparators and storage device.
