FPGA Implementation of an Advanced Traffic Light Controller using Verilog HDL
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2012, Vol 1, Issue 7
Abstract
Traffic lights are the signaling 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), they alternate the way of multi-road users. 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. This paper presents the FPGA implemented low cost advanced TLC system using ChipScope Pro and Virtual Input Output. The TLC implemented is one of the real and complex signaling lights in Kingdom of Bahrain, for pedestrian way included four roads and sensors and camera assisted motorway. The system has been implemented in hardware using Spartan-3E FPGA.
