AN ASSESSMENT OF VEHICULAR TRAFFIC CONGESTION ALONG ABUJA-NASARAWA ROAD WITH EMPHASIS ON KARU BRIDGE TO AYA INTERCHANGE

Abstract

Traffic congestion poses a substantial challenge to efficient road transportation, impacting travel times, fuel consumption, and overall productivity. The Abuja-Nasarawa Road, a critical transportation corridor, faces persistent congestion issues attributed to factors such as increased vehicle numbers, inadequate infrastructure, and poor traffic management. The escalating traffic congestion along Abuja-Nasarawa Road adversely affects the region's productivity and economic development. This study aims to analyze the traffic congestion along the Abuja-Nasarawa Road to improve decision-making regarding road use and transportation system planning. The research design combines qualitative and quantitative methods, utilizing a questionnaire and traffic data collection. The study focuses on the AYA Interchange – Karu Bridge section of the road, a critical stretch facing congestion issues. The methodology involves traffic data collection, including vehicle counts, traffic volumes, and average speeds. Results indicate varying traffic flow rates during morning and evening peak hours. Karu Bridge experiences the highest traffic congestion, with a flow rate of 5433 vehicles per hour during the morning. The qualitative analysis reveals the distribution of road users, with 40% being commercial drivers. The findings reveal a prevalence of traffic congestion attributed to the concentration of economic activities in the city center, leading to increased commuter influx. The study recommends measures such as maintaining and expanding the road network, introducing alternative transportation like a railway service, and completing infrastructure projects like the Apo-Karshi Road.
