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 design, the power circ ...
