ABSTRACT

The goal of this project was to develop effective traffic control methods that could operate 24 hours a day, seven days a week. As the globe becomes more technologically advanced, an increasing number of automobiles enter the public road, adding to the already large number. As a result, a more efficient method of traffic control becomes more attractive than the outdated method of employing traffic personnel.

This traffic light control’s design is divided into three parts: digital logic design, power circuit design, and power supply design. The power circuit design is targeted at lighting the various LEDS as and when they are due, and the digital logic design is based on integrated circuits, which is the modern approach of constructing digital systems.

The power supply is designed to provide a consistent 8V dc supply to power the circuit.

The LEDS were installed on the frame, the driving circuit was created, and the entire system was enclosed in the smoothened frame for this project.

The completed work was put to the test and was found to deliver a consistently high level of performance.

CHAPTER ONE

INTRODUCTION

In today’s ever-expanding world of business and technology, there is an ever-increasing column of vehicles on every road in every corner of the globe. The traffic control light has evolved into a very successful tool for sequential control of the growing number of vehicles on the road, averting what would otherwise have been a recurring saga of heinous accidents at intersections. There have been a variety of methods for accomplishing this, the most common of which being the use of electrical monitoring circuits that are controlled by presto clock. In industrialized countries, the use of traffic officers who would jump up and down at the intersection’s center just to get cars to notice their strict signage has long been commonplace. Many civilizations in developing countries, where traffic flows 24 hours a day, are implementing traffic light regulation. This type of traffic control has numerous advantages that cannot be overstated. For starters, it provides more modern technology that is less prone to errors and their unfortunate consequences. They stand out more at night, providing illumination to the local surrounds, which is crucial for security and adds to the overall aesthetic attractiveness of night life. The technology used to create the design may differ from one location to the next, but the fact remains that an electronic (logic) circuit is used to control a power circuit in every case. The basic digital components of electronic design, such as oscillators, timers, counters, decoders, microprocessors, and so on, make up the electronic logic circuit, while the lamps and drivers circuits make up the power circuit. The digital circuit is programmed to produce an output that is proportional to the design choice. The power supply unit is used to power the logic circuit by generating a constant supply voltage. The output consists of a series of lamps that, depending on the design, are expected to light in a specific sequence.

 AIM OF THE PROJECT

With the rapid advancement of technology around the world, the need for better solutions to problems arises on a daily basis. The mother of invention is necessity. It has become necessary for societies, companies, industries, business ventures, clubs, and other organizations to provide 24-hour service; as a result, there must be a method of controlling the teaming column of vehicles that transport both people and goods to various destinations of that type. The use of traffic light control is the most elegant way of directing motorists. This form of control has a dual purpose. In the daytime, it directs traffic, but at night, it also serves as a light source, illuminating the environment.

METHODOLOGY

The nature of the junction and how far apart they are at different times of the year were given top priority. A lot of design research was done on digital logic design and digital family selection. To make the most appropriate component choice at the most reasonable cost, data books were consulted.

A market survey was conducted after the design, and some of the components used in the design were not available on the market. As a result, other components had to be used, and the circuit had to be rebuilt. Following that, the design work is physically realized by creating and packaging the whole circuitry on the frame. Finally, the work was polished and put to the test.
