Evaluating the performance of Signalized intersection using SIDRA software: A case study in Bahir Dar city, Ethiopia

Abstract

This paper aims to assess the performance of signalized intersections in Bahir Dar City, Ethiopia, utilizing SIDRA software. Signalized intersections play a crucial role in urban traffic management, influencing the efficiency and safety of transportation systems. Through a case study approach, this research evaluates the effectiveness of signalized intersections in Bahir Dar City, focusing on aspects such as traffic flow, delay, and level of service. The study utilizes SIDRA software, a widely-used tool for traffic analysis and simulation, to model and analyze intersection performance under various conditions. Data collection includes field observations, traffic counts, and intersection geometries. The findings provide insights into the current state of signalized intersections in Bahir Dar City are Inadequate split signal phasing and a general lack of need for the signal in favor of a roundabout are the main factors influencing how well an intersection performs. Before improvement, the average wait time and length of the line at the intersection were greater than they were after improvement. So as to enhance the junction by phasing time correction and signal replacement with a roundabout. Finally, the intersection's average delay, queue length, and quality of service have all improved. Accordingly, the findings of the Depo signalized major intersections' performance analysis show that some of the intersections are overloaded or in poor condition and offer recommendations for improvement to enhance traffic efficiency and safety
