A 2019 noise map from the Bureau de Recherches Géologiques et Minières identifies areas where residential, educational, and health buildings exceed Lden noise limit values. It is based on the European Directive 2002/49/EC and uses digital models incorporating traffic, topology, and meteorological data. The map cross-references noise calculations with demographic data to estimate population exposure.
Use Cases
- Identifying residential zones requiring noise mitigation based on Lden exceedance areas.
- Establishing baselines for Urban Travel Plans using traffic and noise propagation data.
- Estimating population exposure to noise pollution by cross-referencing maps with demographic data.
Strengths
- Based on a harmonized European assessment framework (Directive 2002/49/EC).
- Incorporates multiple data sources including traffic, topology, and meteorological data.
- Cross-referenced with demographic data to estimate exposed populations.
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2019-04-01 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
