DESIGN AND CONSTRUCTION OF A MODEL OF AN AUTOMATIC TRAFFIC CONTROLLER FOR ZEBRA CROSSING WITH RECHARGEABLE BATTERY

Abstract

This project is on the Design and Construction of Automatic Traffic Controller for zebra crossing with rechargeable battery. The motivation behind this project is to deign a traffic controlled light that is simple and effective to control the flow of traffic on our single busy roads in Nigeria. Generally, most traffic controlled light due to high cost of maintenance is abandoned when faulty. This project when irnplemented; would be operational all the time because of the incorporation of rechargeable battery and its low cost of maintenance. This project makes use of 40478 (astable multiviberator) which controls the Yellow light and docks the bistable multiviberator with its Reset and Set Output respectively. The Bistable multiviberator (40 L38) controls the lighting of the Red LED and the NOR gate with its Set output. Finally, the NOR gate (4011B) controls the lighting of the Green LED. This project work works perfectly for a zebra crossing road.
