This dataset from Métropole Aix-Marseille-Provence provides a modelled road network base used in strategic noise mapping. It was collected as part of a noise diagnosis project covering road, industrial, and air traffic noise, initiated and managed by the metropolitan authority's Environmental Strategy division (DGA Stratégie Environnementale). The modelled base serves as a support layer for evaluating road traffic noise across the metropolitan area, and is intended for use in environmental noise assessment and mapping applications.Cartographie de Bruit Stratégique La base routière modélisée est une donnée collectée dans le cadre du projet du diagnostic du bruit (routier, industriel, aérien). Ce projet a été initié et géré par la DGA Stratégie Environnementale. La base modélisée sert de support pour évaluer le bruit routier...
