Operational evaluation of Obafemi Awolowo University main gate – Ede Road intersection

Abstract

Vehicular traffic at Obafemi Awolowo University has increased over the years, resulting in delay at The Main Gate – Ede Road Intersection. This paper evaluated its present level of service with a view to addressing this situation. Geometric survey of the intersection was carried out. Peak hour traffic studies were conducted for a week and the traffic characteristics and volume were determined using standard procedure. The level of service (LOS) of the intersection was thereafter obtained. The geometrics of the intersection showed that, two lanes exist on the East Bound (EB) and West Bound (WB) approaches, as well as a dual lane on the North Bound (NB) and South Bound (SB) approaches. The traffic volume count was 1378, 931, 1168 and 1123 veh/h for the NB, SB, EB and WB respectively. The level of service at the intersection is B, thus implying that it exhibits a slight delay.
