Noise mapping as a tool for urban planning

Abstract

<span style="mso-ansi-language:EN-US;mso-fareast-language: PT-BR" lang="EN-US">This paper discusses the findings of an earlier analysis of environmental noise pollution in the north section of the Green Line in the city of Curitiba, involving information about the objective aspects of the measured equivalent continuous sound pressure levels generated by vehicle traffic on this main thoroughfare. An assessment is also made of the environmental impact the avenue produces in a noise sensitive area. Only the main factors that determine road traffic noise, i.e., heavy vehicle flow, road conditions, and average speed of vehicle traffic, were considered in the noise maps developed here. The noise levels recorded on this road exceed the levels recommended by current legislation. This study demonstrates that taking only one control measure does not suffice to counteract noise efficiently. Instead, a plan involving various measures taken jointly is needed to effectively mitigate the problem.
