Abstract:
Maraba intersection in Ilorin metropolis, Nigeria, is a 4-legged traffic warden controlled intersection in a typical urban centre of a developing economy. As a result of the congestion at the intersection and in a bid to ameliorate the frustration experienced by motorists at the intersection, fixed-time traffic signalization was installed at the intersection to replace the manually human controlled signalization. It is however noticed that the congestion experienced at the intersection has become worse despite the introduction of the fixed-time signalization. The study assesses the present performance of the intersection and obtained the LOS of F for each of the legs. A 4-phase fixed-time traffic signalization is proposed to replace the present 5-phase signalization, which if implemented will improve the level of service to D. It is also recommended that to achieve the new level of service the intersection should be redesigned by increasing the number of lanes from the existing 2 to 3 for two of the legs while the only approach with a single lane should be increased to 2 lanes.

Key words:  intersection congestion, traffic warden controlled, fixed time signalization, critical flow ratio , , ,
