FPGA-Based Intelligent Traffic Controller with Remote Operation Mode

Abstract

This paper covers the design and implementation of an intelligent traffic management system for an isolated intersection. The vehicular traffic management system employs Field Programmable Gate Array (FPGA) as the central decision-making unit and combines its speed and high number of I/O with other system components such as the ESP8266 Wi-Fi module, to record real-time traffic information and apportion greentime for each phase of traffic signal. The design and implementation incorporate three different operational modes namely, fixed time mode, sensor actuated mode and remote control mode, to alleviate vehicular traffic congestion and also reduce the risk of accidents at intersections. The incorporation of remote control mode, which enables an authorized personnel to remotely control the traffic, using a cloud-based application running on a portable device, makes this system different from previous works. Simulation using a prototype of the model on a model intersection, shows that the system can reduce waiting time and increase throughput at the intersections.
