Impact of traffic calming on acoustic climate in street surrounding

The paper presents the methods to improve safety and quality of life of people living in the neighborhood of roads and the situation of road users by means of traffic calming. The focus is kept on positive impact of traffic calming measures on acoustic climate in the surrounding of roads. The paper also contains the characteristics of selected impacts of road traffic on the environment together with a general outline of traffic calming as an instrument to mitigate the negative influence. Various possibilities to frame the acoustic climate and reduce transport-related inconvenience by means of different traffic calming methods are present as well. Then a case study (regional road No 824 in Puławy) is used to assess the effectiveness of specific solutions of comprehensive traffic calming with regard to speed reduction and abatement of noise emissions. Analyses are based on measurements’ results (traffic volumes, driving speeds and noise levels) and on acoustic calculations performed by the authors as part of their own study (internal research & development program of EKKOM). On the basis of measurements’ results and calculations the paper also addresses the problem of lack of correction factors related to traffic calming in the calculation model and the one of errors in noise modeling while preparing the case study.
