CHAPTER ONE
1.0 INTRODUCTION
In the ever fast-growing world of
business and technology today, there has become an increasing column of
vehicles on every road in different place of the world. Traffic control
light has become a very effective tool for sequential control of the
teaming number of vehicles on the road to avert what would have been a
recurrent saga of ghastly accidents at the junctions. There have been
many ways of achieving this, uppermost among these being the employment
of electronic monitoring circuits that which is controlled by presto
clock.
In developed countries, the employment of traffic
personnels who would be jumped up and down at the centres of the
junction just for the motorists to acknowledge their rigorous signs has
long come of age. In developing countries where 24 hours traffic flow is
involved, many societies are adopting the usage of the traffic light
control. The advantage offered by this method of traffic control cannot
be over emphasized. For one, it offers a more advanced technology that
is less prone to miscalculation and its regrettable occurrence. They
stand out better at night, then offer illumination to the immediate
surroundings which become important for security purpose and in general
add to there entire aesthetic beauty of night life.
The
technology behind the design may vary from place to place, but the fact
remains that in all cases an electronic (logic) circuit is made to
control a power circuit. The electronic logic circuit is normally
composed of the basic digital components of electronic design which
includes oscillators, timers, counters, decoders, microprocessors,
etcetera, while the power circuit includes the lamps and the drivers
circuits. The digital circuit is designed to give an output commensurate
to the design choice. The power supply unit is designed to generate a
steady supply voltage which is used to power the logic circuit.
The output consists of a series of lamps which are expected to light in
a particular sequence depending on the design. By the logic circuit
design, the lamps are made to come up in a particular sequence depending
on the design with each colour meaning different motional status of the
vehicles in that column.

ABSRACT - [ Total Page(s): 1 ]This work has been aimed at efficient means of controlling the traffic effectively for twenty-four hours. As the world is growing technologically more and more vehicles jump into the public road adding to the already existing number. Consequently, more efficient way of controlling the traffics becomes more desirable as compared to the obsolete way of using the traffic personnel’s. The design of this traffic light control is grouped basically into three; digital logic des ... Continue reading---
