Optimización de los ciclos semafóricos para mejorar la capacidad y nivel de servicio en los puntos críticos de congestión vehicular del cantón Rumiñahui, 2021.

Abstract

The objective was to optimize traffic signal cycles to enhance the capacity and service level of critical points facing vehicular congestion in the Rumiñahui canton, 2021. By measuring traffic flow indicators and considering variables such as geometry, traffic volume to determine the peak hour, cycle times, and signal phases, an operational analysis of capacity and service level was conducted at signalized intersections. The methodology used was the Highway Capacity Manual (HCM 2010) and complied with the guidelines established in the Ecuadorian Technical Regulation RTE INEN 004:2012, Part 5. It was determined that out of the 5 analyzed and evaluated conflictive intersections, 4 exhibited deficient service levels ranging from type C to F. Consequently, improvement proposals for signal cycle designs were developed, complemented, and validated with the PTV Vissim student version software, resulting in improved service levels and reduced delay times, directly impacting traffic flow. It was concluded that effective traffic management at intersections through low-cost, high-impact redesigns of signal cycles and phases can enhance service level outcomes, optimizing urban mobility and road safety for both pedestrians and drivers. It is recommended to conduct periodic operational analyses to redesign or configure signal cycles according to traffic volumes and other characteristics reflecting the current reality of signalized intersections, given that vehicular flow demand is constantly variable.
