CHAPTER ONE

INTRODUCTION 1.1 Background 

Most roads in Nigeria urban areas are usually congested, some all-day, others during rush hours. It was found that larger part of this problem is that due to congestion at road intersections. However, traffic light systems have long been invented to control this problem. Most of these traffic light control systems are imported thereby making them expensive. Traditional traffic light control systems are designed to function at only a particular type of traffic intersection. For example, a control system that was designed for a cross-junction may not serve at T-junction. 

          This project work deals with a microcontroller-based traffic light control system that has the ability to control any type of y- and cross- traffic intersections. It is indigenous as well as versatile in its control functions as regards y- and cross-junctions. This has the effect of

drastically reducing the design cost.               

1.2 Aim and Objectives

 This project aims at developing an 8051 microcontroller-based versatile y- and cross- traffic light control system which can be deployed at road intersections for traffic control. It can be used as a teaching aid in schools for various road users. The purpose of this project work is to develop a versatile system that can control any type of cross- and y-traffic junctions to assist and to educate the general public on automobile-automobile and automobile-pedestal interactions at road intersections.
