Microcontroller Based Traffic Light Control System

Largest cities in Turkey as well as largest cities in world have the problem with traffic congestion. Traffic congestion in tightly populated urban areas negatively impacts the living standard of population. A long time delays and emergency cases at traffic light intersection are one of basics reasons of traffic congestion. The control system based on PIC 16F877A is designed in the research work to provide either normal or emergency mode cases for vehicles and reduce of traffic congestion at intersection road. The proposed control system of six ways and four junction’s intersection traffic light is developed for normal and emergency mode cases. The purpose of the research work accomplished by Simulink on Proteus Design Suite 8 software and prototype implementation of traffic light control system for a six way and four junction’s road intersection.
