Análise de interseções no centro de Pato Branco - PR: um estudo de caso para melhoria do tráfego

Abstract

The problem of urban mobility is quite common in almost all Brazilian cities due to the lack of investments and projects aimed at this area, which generates major economic and social problems. Political carelessness and disorganized growth further amplify the problems of inefficient urban mobility. Because of that, this work aims to analyze intersections of the city Pato Branco-PR analyzing level of service for roundabout, criteria adopted by the public body for traffic lights and solution, if necessary, in intersections that do not have any type of traffic control. A case study was made using the methods of the Manual of Intersections of the National Department of Infrastructure and Transport (2005) and of the HCM - Highway Capacity Manual - (2010), raising the number of vehicles movements, points of conflict of near accidents and then analyzing the data obtained according to both DNIT and HCM criteria for the current time and for a 10-year project horizon year. In the case of the roundabout the current service level is B and for the project horizon year this roundabout would not serve its purposes efficiently. It can be concluded that poor public management of urban mobility can lead to great economic and social losses and greater danger in traffic, and that a continuous count is necessary in the main intersections of cities, especially in accidents so that the city can analyze and take the best measures to remedy such problems.
