Noise mapping for the management of urban traffic flows

Abstract

This study analyses the EU policies related to the assessment and management of traffic noise in urban areas. The analysis is based on the application of noise maps using Cadna A software for the central part of Kaunas city, Lithuania. Data on the traffic flows, height of buildings, speed limits combined with actual noise measurements are used as an input to the dispersion model. The assessment of noise is based on the guidelines of the method 'XPS 31-133' defined in the European Commission Recommendation C(2003)2807. The formation of noise maps has raised the need for qualitative determination of traffic flow type and the elaboration of acoustical equivalent concept for different modes of transport. An analysis of alternative noise maps (scenarios) should be considered as an important component of urban traffic flows management.
