Modelagem do ruído de tráfego rodoviário urbano: uma revisão da literatura

Abstract

Road traffic induces noise pollution, which have negative impact on human health. To address this problem, urban noise mapping is important in order to understand the phenomenon, formulate mitigation plans and evaluate interventions. The purpose of this literature review is to present the tools and parameters currently used in noise pollution modeling related to urban road traffic. 274 studies were analyzed, highlighting relevant contributions, inconsistencies and research gaps. It was observed the extensive use of commercial software but, recent studies, indicate the use of geographic information systems (GIS) with specific developed supplements. These systems allow better integration with different databases and implementation of new prediction models. They generally use attributes such as volume, speed, percentage of heavy vehicles, pavement type, road geometry and buildings shape. In the Brazilian case, it is highlighted the still little use of GIS software and the lack of studies about behavioral factors, such as the use of car horns.
