“Evaluación de las intersecciones semaforizadas existentes y posibles zonas de ampliación en el cantón Lago Agrio, provincia de Sucumbíos”

Abstract

This research evaluated the existing signalized intersections and potential expansion areas in Lago Agrio Canton, Sucumbíos Province, to enhance traffic flow and reduce congestion at high-traffic intersections. A qualitative and quantitative methodology was employed, incorporating descriptive, explanatory, bibliographic, and field research. Data collection instruments included vehicle counting through observational traffic surveys and collection sheets for geometric data and on-site traffic signal conditions. The results primarily included vehicular flow data, road capacity, signal cycle lengths, and peak traffic hours. Data analysis identified problematic intersections, exhibiting significantly low service levels, reaching level E, and excessively long signal cycles with green, red, and amber times. These evaluations were conducted following the Highway Capacity Manual. After analyzing the data, it has been suggested that the service quality at signalized intersections should be enhanced to reduce traffic congestion in the region. This procedure will undoubtedly lead to a smoother and more efficient traffic flow, benefiting drivers and pedestrians alike. In line with the Ecuadorian Technical Regulation, Part Five, implementing a signal system is designed for each of the three Canton's potential expansion areas. In conclusion, the existing signalized intersections require restructuring of their signal timing to enhance vehicular and pedestrian mobility. The competent authorities should consider this research's proposed signalization implementation and restructuring.
