DESIGN AND IMPLEMENTATION OF EFFICIENT TRAFFIC LIGHT CONTROLLER SYSTEM WITH TIMER DISPLAY

Priyadarshini M, P.Prasanna Kumar

Abstract


An efficient traffic control system is designed to manage the road traffic is designed in this paper. Traffic lights are the signalling devices used to manage traffic on multi-way road. These are positioned to control the competing flow of the traffic at the road intersections to avoid collisions. By displaying lights (red, yellow and green), and time they alternate the way of multi-road users depending on the peak and off-peak hours. The implementation of traffic Light Controller can be through a Microcontroller, Field Programmable Gate Array or Application Specific Integrated Circuit. FPGA implementation is advantageous over ASIC and microcontroller; number of IO ports and performance compared to microcontroller and implementation with FPGA is less expensive compared to ASIC design. The system is implemented on VERTEX6 chip and simulation results are proven to be successful. Theoretically the waiting time for drivers during off-peak hours has been reduced further, therefore making the system better than the one being used at the moment.
