The study is to investigate the operational performance of Ibrahim Taiwo-Civic Center Signalized Intersection and this was achieved through determination of operational traffic volume, establishment of performance parameters and lastly suggesting appropriate measures that would improve the general performance of the intersection under study. Observatory manual method was used to collect the relevant data and Highway Capacity Manual 2000 equations were used to analyze the set data’s. After analyzing the relevant data, the following conclusions were drawn; Ibrahim Taiwo approach possessed the highest value of traffic flow followed by Isyaka Rabiu and lastly Civic Center which tends to have the lowest value. But regarding the control delay, Civic Center approach possessed the highest value of 185 secs followed by Ibrahim Taiwo which possessed 65 secs and Isyaka Rabiu having the lowest value of 48 secs. These results clearly shows that the efficiency and smooth flow of traffic is always associated with adequacy of intersection geometric layout.
