A 2021 aggregation of strategic noise maps for national roads in France, created by CEREMA and published by the Bureau de Recherches Géologiques et Minières. The maps represent areas where Lden and Ln noise indicator boundaries are exceeded, as defined by European Directive 2002/49/EC. They serve as information documents for assessing environmental noise exposure.
Use Cases
- Assess exposure to environmental noise from national roads based on the Lden and Ln indicators.
- Identify areas exceeding noise limit values for targeted traffic management as part of an Urban Travel Plan.
- Supplement Local Planning Plans with graphic noise data for land-use zoning decisions.
- Establish baselines for noise pollution around major road infrastructure.
Strengths
- Created by CEREMA, a French public expertise body, suggesting authoritative sourcing.
- Aggregated using the QGIS MIZOGEO plugin, indicating a standardized geospatial processing method.
- Based on European Directive 2002/49/EC, ensuring a harmonized assessment framework.
