THE ROLE OF TRANSIT BELT-ROADS IN URBAN TRAFFIC NOISE REGIME

Full text

Road traffic is a main source of urban noise. Therefore, reducing traffic flow in cities stands as a common noise management practice. This research was conducted in the city of Caransebeș, Romania, from 2012 to 2014. The sample consists of three sets of LAeq noise values measured in 170 monitoring point stations along roads. The goal of this research is assessing noise level changes between two distinct situations: with and without traffic flow through the city. Thus, 2040 data values were statistical analyzed. We used interpolation tools for spatial modeling and correlation testing. The results highlight that noise pollution scale down for more than 50% of urban space when transit traffic uses the belt road. However, high noise levels persist in some edge zones. Thus marginal areas claim enhancement solutions.
