Analysis of Spatial Development Possibilities of Properties Endangered by Road Noise in the Context of Permissible LN and LDWN Indicators

The paper deals with the problem of road noise pollution in the context of spatial development. The analysis was motivated by the changes in the permissible noise levels that occurred on 1 October 2012 and the high urban pressure on areas located along the main traffic routes. On selected examples of sites located in the districts of Bemowo and Białołęka in Warsaw, the location of land functions is shown on the background of the course of isophones of acceptable noise levels. The analysis was based on data from acoustic maps for Warsaw developed in 2012 and 2017, planning studies, database of topographic objects and current state of development. Based on 20 features and 9 surface and quantitative indicators, determined using ArcGis software, the degree of road noise pollution in planning terms was shown. The analysis has been demonstrated that the changes in legislation have resulted in the acoustic “freeing up” significant areas along the main road, express and accelerated main roads and a reduction in the number of buildings that were considered to be at risk of noise pollution by the law before 2012. The acoustic release indicators for the general area were in the range of 0.71–0.74 for LN and 0.56–0.74 for LDWN. In relation to acoustically sensitive areas the results were in the range of 0.81–0.84 for LN and 0.64–1.00 for LDWN.
