Diseño de una metodología para la determinación del modo de operación de un sistema semafórico en el corredor avenida calle 80 entre carrera 112 y carrera 120 en la ciudad de Bogotá D.C.

Abstract

This research aims to design a methodology to determine the most appropriate operating mode for a traffic signal system in urban corridors, using Avenida Calle 80 between Carrera 112 and Carrera 120 in Bogotá D.C. as a case study. The study arises from the need to improve traffic management in areas with high vehicular demand, public transport, freight transport, pedestrians, and cyclists, where traditional traffic signal schemes may be insufficient to respond to traffic variability. The research included the characterization of the current traffic signal system, the analysis of the physical and operational conditions of the corridor, and the evaluation of indicators such as saturation, demand variability, road safety, and coordination between intersections. Subsequently, a five-step methodology was applied to assign traffic signal operating modes, including fixed-time, actuated, responsive, and adaptive control, according to the actual conditions of each intersection. Additionally, a microscopic traffic simulation was developed for both the current and optimized scenarios in order to compare the operational performance of the corridor. The results show that traffic signal optimization improves the average network speed, reduces delays, strengthens coordination between intersections, and increases the efficiency of vehicular flow processing. Therefore, the proposed methodology represents a useful technical tool to support decision-making in urban traffic signal management and may be replicated in other corridors with similar characteristics.
