Abstract: Traffic light control systems are widely used to monitor and control the flow of automobiles through the junction of many roads. They aim to realize smooth motion of cars in the transportation routes. This paper is designed to develop a traffic signal based on traffic density and also innovative control to clear the traffic for ambulance. During normal situation, the signal timing changes automatically by sensing the density of vehicles. Conventional traffic light system is based on the fixed time concept allotted to each slots. The proposed system uses and PIC16F877A micro controller (Harvard architecture family) interface with sensors that change the junction timing automatically to avoid unnecessary waiting of drivers. IR sensors are used in this paper to detect the density of the traffic. The Bluetooth operated by Android device override the set timing and give green signal in the desired directions whereas blocking other roads by red signal. Thereby providing traffic clearance for emergency vehicles.
Keywords: Traffic light control systems, automobiles, transportation routes, traffic signal, emergency vehicles.
