Abstract: An efficient traffic control system is an important issue to reduce the traffic congestion. In this research, area based traffic control system is implemented for four-way intersection by using image processing techniques. This system is a vehicle-actuated signal type control system such that traffic cycle time can be varied and related to the actual demands by traffic. The CCTV traffic video file at a station in Mandalay is utilized as the input for the image processing. The amount of vehicles bounded on the road is estimated and defined as the traffic area with the numbers of pixels.
