O uso de simulação em análise operacional de tráfego urbano: estudo de caso sobre rotas alternativas à Ponte Sérgio Arruda em Macapá-AP

Abstract

The Sérgio Arruda Bridge, located in the city of Macapá-AP, since its inauguration in 2003 has been consolidated as the main access route to the North Zone of the city. During the last twenty years, the bridge has presented several pathological problems that have condemned its structure and demanded the implantation of a new overpass for the region. Taking into account the hypothesis that for the construction of a new road project on that spot it will be necessary to demolish the existing bridge, it was observed the need for a study that could predict the traffic flows that will be interrupted by this demolition. Based on the methodology of applying traffic volume counts, the volumes of the main interference flows in the case studied were surveyed and the generated data were used to perform traffic simulations with the objective of predicting the scenario. Given the survey of existing alternative routes within the study area, some scenarios were proposed and analyzed through simulations, in order to provide a better solution for the generated traffic problem. The software chosen to run the simulations was Autodesk's InfraWorks due to the easy access to the program and the tool to generate three dimensional animations that helps to visualize the problem. The generated results are presented through comparative graphs that contribute to the analysis. The graphs demonstrate the improvement in traffic performance with the implementation of the new bridge when comparing the current and future scenarios, as well as point the complexity of managing the traffic during the construction period, where none of the proposed scenarios was able to effectively make up the demands studied.
