“…They alternately direct traffic to stop and proceed at intersections using red and green light signals as per the pre-determined time settings (Dutta and Dan, 2020). The purpose of the traffic signal, therefore, is to assign the right-of-way to road users and thus facilitate safety by ensuring the orderly and predictable movement of all traffic on the roadways (Adeleke et al, 2016;Demir and Demir, 2020;Krishna et al, 2018;Mathur and Mathur, 2018;Sipos et al, 2015).…”

Intersections in urban centers, especially those without any form of signalization, are accident hotspots. This, therefore, calls for ef-fective and efficient traffic management at the intersections for improved safety and efficient traffic flow. This study aimed to improve traffic flow at the Gaa-Akanbi intersection in Ilorin, Nigeria, using a traffic signal scheme. A traffic volume study and geometric features survey was carried out at the intersection. The traffic volume study was performed to determine the number, movement, and classification of vehicles at this intersection using the manual method of traffic count, while the geometric survey of the intersection was done using tape and Total Station. A 3-phase traffic signal was proposed. The optimum cycle length and signal setting were determined using SIDRA Intersection software by adopting the maximum average passenger car unit on the intersection and targeted level of service (LOS) "D". A traffic signal plan with a cycle length of 150 seconds was designed for the intersection. The amber time was considered to be 2 seconds for all phases, and green time of 48, 46 and 38 seconds was gotten for phases 1, 2 and 3, respectively; this timing ensures that minimum delay occurs at the intersection. The proposed traffic signal should be adopted at the intersection by the metropolitan traffic management agency to improve traffic management.
