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.
