Design of a 4-Junction Road Intersection Intelligent Traffic Controller System in Ado-Ekiti, Ekiti State, Nigeria

摘要

Most roads in Nigeria cities are usually congested, some throughout the day, others during rush hours. Larger part of this problem is as a result of congestion at road-intersections. However, traffic-light systems have long been invented to control this problem. Most of these traffic light control systems are imported thereby making them expensive to acquire and adapted to the local circumstances that most time depend on the attitude and the way of life of the people. Traditional traffic light control systems are designed to function at only a particular type of traffic intersection. For example, a control system that was designed for a cross-junction may not serve at T-junction.This paper presents a design with a microcontroller-based traffic light control system that has the ability to control any type of 4-junction and cross traffic intersections based on traffic density, in an attempt at curbing traffic offences. It is indigenous as well as versatile in its control functions and has the effect of drastically reducing the design cost.
