Avaliação da sinalização semafórica de cruzamentos em uma avenida de Alegrete/RS

Abstract

Traffic lights, in addition to controlling traffic flow, have the function of preventing conflicts at intersections. The growth of the vehicle fleet is on the rise and, consequently, travel time is also increasing. Due to this problem, the importance of the study of traffic is highlighted, aiming at the fluidity and reduction in the travel times of users on the roads. For traffic signal programming to perform its functions correctly, it is necessary to know the demand and supply on the road. In this way, the present work carried out a quantitative analysis through filming in order to know the demand, supply and the current cycle times at three intersections in the avenues Assis Brasil and Dr. Lauro Dornelles in the city of Alegrete / RS. Using the methods of Webster and Degree of Maximum Saturation, new cycle times were found, which were later compared with each other and with the current cycle times at crossings. In general, the benefits of the proposals through reprogramming using the methods of Webster and Degree of Maximum Saturation the method that proved to be most significant for the demand of all crossings was the method of Webster. It was found that for there to be fluidity it is necessary that the cycle times are appropriate for the different periods of the day.
