Title: Noise mapping as a tool for urban planning
Authors: Fiedler, P E K; Zannin, P H T
Abstract: 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.
