Abstract:
Since 2009, the EU Commission is working on harmonized assessment methods according to Article 6 of the EU Environmental Noise Directive. This will be adopted through an amendment of Annex II of the Directive and applied mandatory in 2019 for all Member States. In September 2012 appeared the "JRC Reference Report - Common Noise Assessment Methods in Europe ( CNOSSOS - EU )" of the Joint Research Center, which aims to improve the reliability, consistency and comparability of the noise assessment results in the EU Member States and forms the basis for the amending Annex II . To assess its proposed policies in a first step, the emission model of the already existing national computation method RLS - 90 for road traffic noise is compared in detail to the new method of CNOSSOS - EU. The investigations are carried out based on typical test scenarios. Important parameters such as pavement, fleet composition, speed and pitch can be varied. Temperature corrections are considered separately for their effect in the CNOSSOS-EU model. Based on the results of the comparison, recommendations for the future use of the harmonized assessment method for road traffic noise are given and practical simplifications of the methods for national use are demonstrated.
