Strategic Noise Mapping in France to 2023: Coupling a national database with the open-source model NoiseModelling
Résumé
The European regulation 2002/49/CE imposes the realization of strategic noise maps, every 5 years, in order to evaluate the impact of roads, railways, airports and the main industries on the inhabitants. For the 2023 deadline and for roads and railways outside agglomerations, France has decided to create a national database, called PlaMade, which gathers all the necessary input data (traffic, building, population, relief...) in a unique format, a COVADIS GeoStandard. On the basis of these data, and using the open-source noise propagation calculation tool NoiseModelling, all the indicators and maps have been produced for the first time in an automatic way at the scale of the whole national territory. This paper presents the technical and methodological details of the coupling between the PlaMADE database and the NoiseModelling tool.
