DESIGN OF TRAFFIC SIGNAL CONTROL SYSTEM AT ORLU JUNCTION, IHIALA, ANAMBRA STATE, NIGERIA
Abstract: The vast increase in population results in number of vehicular movement which contributes to volume of traffic at road intersections. This traffic jam is much during festive periods, causing delay which has negative impact to the economy. No one can easily predict the time of journey arrival due to gridlock at intersection on highways. This inefficient traffic movement is caused by absence of traffic control systems. Hence, this study had …
