Real-Time Traffic Light Controller System based on FPGA and Arduino

Abstract

This paper aims to implement and simulate the real-time traffic light system by using an FPGA programmed on the Spartan 3E platform and a micro-controller programmed on the Arduino Mega platform. The system is designed to manage street traffic control and assist walkers to move freely to prevent automobile crashes. The simulation of a traffic light system is executed using an FPGA joined to an electronic circuit board on Spartan 3E through the external expansion and also using an Arduino Mega platform linked to the same electronic circuit board. During the simulation of the traffic light system, C++ programming language is used to programme The Arduino platform while the VHDL is used to programme the FPGA platform. Furthermore, some semiconductor components such as switches, resistors, sensors, and LEDs are used to build the electronic circuit to obtain the best performance of the traffic lights. The comparison between the two designs is done dependant on some parameters such as cost, speed, memory space, and other parameters which are considered very important when designing the traffic light system. To solve congestion problems at intersection roads, it is necessary to create a simple and reliable traffic control system.
