The design and implementation of a four – way traffic light control circuitThe design and implementation of a four – way traffic light control circuit

Thesis Abstract

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 circuit and the power supply design. The digital logic design is based on integrated circuits which happens to be the modern way of designing digital systems, the power circuit design is aimed at lighting the different LEDS as and when due, while the power supply design strives to achieve a constant 8V dc supply for powering the circuit.

For this work, the frame with the LEDS mounted on it has been constructed, the driven circuit was implemented and the entire system enclosed in the smoothened frame.

The realized work was tested and guaranteed to give a firmly good level of performance.
