Design an Intelligent Traffic Light Controller

Abstract

The aim of this research is to design an intelligent traffic light control system using Field Programmable Gate Array (FPGA) technology. And Very High Speed Hardware Description Language(VHDL). A structure of four road intersection (Al-Raiyah intersection) has been selected as reference site,which is located in Al-Nasiriyah city, Iraq. This intersection interconnects Bent-Al-Huda hospital, civil defense directory, the international high-way, the police office directory, and the railway station. In addition to utilizing a regular Traffic Light Controller (TLC), multiple level of functionality such as adding a standby control signal have been considered in this design. Moreover, the motion sensor handling part, special request implementation, and loaded traffic design have been taken into consideration. Its function was verified and simulated using ModelSim.
