Abstract: 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. This newly developed project will enable the traffic light to switch from red to green based on traffic density. The simplest way for controlling a traffic light uses timer for each phase since, we proposed a system for controlling the traffic light by image processing. The system will detect vehicles through images and the image sequence will then be analysed using digital image processing for vehicle detection, and according to traffic conditions on the road traffic light can be controlled.
