ROAD ANALYSIS OF THE NATIONAL HIGHWAY PE-1S IN TACNA: EVALUATION OF A GRADE-SEPARATED INTERCHANGE TO MITIGATE TRAFFIC CONGESTION

Abstract

This research aims to conduct a road analysis of the national highway PE-1S that crosses the urban area in the city of Tacna, focusing on the evaluation of a grade-separated interchange as a solution to traffic congestion. Using Synchro software, traffic flows are examined, and strategies are identified to optimize circulation in an urban environment characterized by a growing number of vehicles. Congestion in Tacna, exacerbated by deficiencies in signage and the geometric design of intersections, negatively impacts the quality of life of drivers and vehicle performance. This research proposes the construction of a grade-separated interchange by lowering the national highway, which is expected to improve the level of service to grade A, allowing for more efficient vehicle flows. The research is based on traffic counting methods and road analysis, providing a solid foundation for decision-making in road infrastructure. Through a comprehensive approach, the aim is not only to improve infrastructure but also to manage traffic effectively, thereby addressing both current and future congestion issues in the city of Tacna.
