Improvement of city noise map production processes and sensitivity analysis to noise models inputs

Résumé

The relevance of noise maps for large cities following the European Directive 2002/49/EC is questionable,because of poor quality or insufficient accessibility of input data and the large number of input parameters. Inthe framework of the CENSE project, a sensitivity analysis of noise mapping models to their inputs is proposedin two parts. On one hand, the integration of different sources of data, from academic or open access databasessuch as OpenStreetMap, was analyzed. On the other hand, a global sensitivity analysis with the Morris methodwas carried out on 15 of the input parameters of the CNOSSOS-EU models (Directive UE 2015/996). Thesetwo studies help to better label and qualify the input data by prioritizing some sources of information andparameters. All these developments were integrated into the open-source tool NoiseModelling ensuring thereproducibility of the results. Acoustic predictions were also compared with available online noise maps for afew French cities.
