Análise de viabilidade para implantação de semáforo em uma interseção em nível no bairro Mossunguê, cidade de Curitiba/PR

Abstract

The use of stoplights has been a common practice in the crossings of big cities and capitals of Brazilian States. When the intersections do not have stoplights, they tend to show clustering and queues, mainly at peak hours. One of these intersections is characterized by the Monsenhor Ivo Zanlorenzi and Luíza Mazetto Baggio Streets, located in the Mossunguê neighborhood – municipality of Curitiba/PR. In this manner, the present research study investigated the technical feasibility of the use of stoplights in the selected intersection, aiming at increasing traffic capacity in the minor roadway. The experimental protocol included traffic counting, analytical calculations for the determination of the current traffic capacity, project of stoplights for the current and designed years and traffic simulations with the SUMO software. It was noticed that the stoplight brings benefits to the minor roadway (Luíza Mazetto Baggio Street), but the traffic in the major roadway (Monsenhor Ivo Zanlorenzi Street) depicted great reductions in the average speed and higher delays. A third alternative proposed in the investigation – the implementation of one-way traffic circulation in the Luíza Mazetto Baggio Street – was found to be the most feasible one at a first glance, since the traffic conditions in the minor roadway were improved and the traffic circulation in the major roadway was not seriously compromised. However, such an alternative demands further studies because the practical traffic capacity is reached in the current year (2023) and according to Brazilian traffic manuals. Also, the impact of this choice in the surrounding streets and that operate with two-way traffic must also be analyzed.
