Avaliação da sinalização semafórica na extensão longitudinal da rua General Sampaio na cidade de Alegrete/RS

Abstract

This work presents a study of the operational situation of the traffic lights implanted along Rua General Sampaio in the city of Alegrete / RS. By means of this it is tried to suggest improvements to increase the operational efficiency of the signal system. For its realization, theoretical references about the traffic lights and the calculation methods used for the programming of each luminous indication were approached. A comparative study was carried out between the current operation, verified through the measurement of the current cycle times, traffic behavior and local organization, and the ideal operation, calculated in this work. Next, the behavior of the traffic in relation to the offer yielded to the crossings by the cycle times of the semaphores was presented. It was concluded that it is possible to promote the increase of traffic flow in the extension of General Sampaio Street by adjusting the capacity of the crossings to the variation of the demand, through the adaptation of the cycle times in the traffic lights in relation to the flow of vehicles, as well as by increasing capacity by employing modifications in auxiliary signals.
