  • Abstract

     

    Air Rhône-Alpes, Acoucité and the Technical French State Services (CEREMA) have developed an environmental platform combining air quality and noise pollution on the Rhône-Alpes region. This platform, named ORHANE (Observatoire RHônalpin des Nuisances Environnementales - Rhône-Alpes region's Observatory of Environmental Nuisances) has been developed to identify and prioritize areas of overexposure to air and noise pollution. The information is delivered to the public as well as the decision makers who need reliable diagnoses in order to implement action plans. Transport activity is the major source of nuisance for both air and noise pollution. Therefore, a very precise work was conducted on atmospheric and acoustic emissions of transport and on their dispersion modeling. Thus the result is a regional map of air quality and noise pollution. Thanks to the combination of models at different scales, this map is consistent and precise for both regional and local scale. Currently, work is in progress to extend this platform to the larger territory of the new region Auvergne Rhône-Alpes and to update the current database. Moreover, this platform will be opened to the public in 2016 and its current results will be promoted to the local authorities in order to identify the overexposed areas and gradually lower them.
