Abstract: The growth of traffic at an intersection on many streets and highways is a major concern to travelers, administrators, merchants, developers and the community at large. Its detrimental impacts in terms of longer journey times, higher fuel consumption, greater transport costs and changing investment decisions are increasingly recognized and felt across Akure Metropolis. Intersection reduces the effective accessibility of residents, activities and jobs resulting in lost opportunities for both the public and business. This issue is now a great concern for Nigeria and major cities in Akure Metropolis. This project assessed the traffic at an intersection within Akure metro\polis namely Oloko which takes its course from Ife road named Leg A Owo/Ado road, named leg B and Cathedral road named leg C. Traffic census was carried out for period of 5 days (Monday-Friday) between 7:30 am-8:30 am-10:00-11:00 and 3:30 pm-4:30 pm daily. Level of service and congestion measure using Microsoft Excel Package Software and travel time and cost of congestion analysis were done for the congested intersection. Accordingly traffic volume, flow and delay were estimated. The maximum safe speed (85th percentile) was 68.17 km/h which can be used for determination of safe sight distance and design speed. Also the minimum safe speed at 15th percentile was 43.27 km/h. From the derived data, vehicle occupancy of car/taxi has the highest percentage occupancy which is 71.49% followed by buses and mini-trucks which is 16.34% because of the vehicle connecting the main empress Akure road. It was established that the intersection is close to the free flow saturated as the degree of saturation gotten is 0.89<1 and closed to be uniform flow. Furthermore, an average delay data collected during the peak period is 3.62 sec while during the off peak period is 4.23 sec.
