“Propuesta de diseño geométrico para el mejoramiento del intercambiador de tránsito del sector de Chacapamba, de la ciudad de Azogues”

Abstract

This project analyzes the traffic interchange in the Chacapamba sector, where the “24 de Mayo” Avenue and the E-35 Highway, as established in the Ecuadorian Road Regulations 2012 (NEVI 12 by its Spanish acronym), are connected. The purpose of this analysis of the roads is to offer geometric layout alternatives that improve the level of service and safety and eliminate problems such as vehicular counterblow. Once the appropriate design is made, the traffic conflicts in the area will be resolved, providing an adequate response to current and future traffic jams. The starting point of this project was to know the operation of each road access, the volumes, the traffic composition, and the topographic survey of the study area. The next step was to collect information such as vehicle counts for seven consecutive days and fuel consumption records provided by the Agency for Regulation and Control of Energy and Non-Renewable Natural Resources. With the data obtained, two alternatives were designed according to the regulations of the Ministry of Public Works (MOP 2003 by its Spanish acronym), NEVI-12, and NCHRP for overpasses and traffic circles that complied with an efficient structure; they were modeled in Vissim 10 software to visualize the performance of each proposal. Finally, the most viable alternative was defined for a 20-year design period, geometric design, modeling, and drawings demonstrating the operational changes' feasibility.
