ABSTRACT

This study focuses on addressing traffic congestion and travel time unpredictability along the Lagos-Benin Expressway segment from Oluku Terminal to Five Junction in Benin City, Nigeria. It aims to identify congestion hotspots, analyze traffic trends, assess travel speeds, investigate delay patterns, and propose solutions for improved transportation efficiency. This research offers practical insights for reducing congestion, enhancing daily commutes, and minimizing environmental impact, with implications for infrastructure planning and urban sustainability.

The study involves a traffic volume analysis using the Manual Classified Count (MCC) method, in order to identify the peak hours and traffic composition at different sections of road along the study route. Additionally, a spot speed study measures vehicle speeds and determines the average operating speed of the road users. Finally, travel time and delay studies assess delays and potential congestion spots by using the floating car technique at both peak and off-peak hours.

The traffic survey found two peak periods: 8am – 10am and 5pm - 6pm. Over 80% of traffic consists of passenger cars and mini/small buses. The average operating speed or the study section falls within 51-61km/hr and aligns with the design speed of the road. The average delay is 9 minutes, which is 45% of the actual travel time (20mins) and 60% of the ideal travel time (15mins). Delays stem from multiple factors such as; driver behavior, breakdowns, accidents, road characteristics and pavement conditions.
