ABSTRACT
A
microcontroller-based Versatile Traffic Light Control System/Trainer has been
designed and implemented in the course of this project. The system can control
traffic lights in all types of y- and cross-junctions. Two major aspects of the
system are the hardware subsystem and the software subsystem. Each subsystem
was first broken down into simpler parts or modules and each module was
designed from first principles to get the required functional behavior. The
entire system was then integrated into one functional unit and tested using a
carefully laid-down test plan. The versatility of the system was made possible
by the use of a microcontroller which enabled the researcher to use software to
achieve a versatile, flexible and cost-effective solution. The system can
double up as a training kit for undergraduates that are interested in learning
traffic light control system design and operation.
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.
1.3
Justification
Since this work is indigenous,
it can serve to replace the imported ones. It can also reduce the cost of
design and implementation since addition of few instruction lines to the
control program will make the control system function at any type of road
intersection. The software program for this system can be modified to
incorporate more functionality. This system/trainer also serves as a learning
aid.
1.4
Scope of the Work
This versatile traffic light
control system is intended to control a wide range of y- and cross- road
intersections. In this work, we limit ourselves to the control of the following
types of traffic junctions:
Automobile-automobile
cross-junction Automobile pedestrian cross-junction
Automobile-automobile
Y-junction using LEDs
Automobile-automobile
Y-junction using lamps via dc relays
This project work is flexible
in that the control program can be modified to incorporate other types of
traffic junction control.
