European Directive 2002/49/EC mandates strategic noise mapping for major transport infrastructure. This dataset contains type A noise maps for the A50 road network, showing areas exposed to more than 55 dB(A) Lden and 50 dB(A) Ln indicators. The maps are produced by the Bureau de Recherches Géologiques et Minières and were last updated in 2020.
Use Cases
- Modeling population exposure to road traffic noise based on Lden and Ln indicators
- Assessing compliance with EU noise regulations for major road infrastructure
- Planning noise mitigation measures around the A50 road network based on isophone curves
Strengths
- Maps are based on standardized EU noise indicators (Lden and Ln) defined by Directive 2002/49/EC
- Data is produced under the authority of the prefect of the department, suggesting an official source
- Noise zones are plotted by step of 5 dB(A) from defined thresholds
Limitations
- Last updated 2020-01-10 00:00:00; freshness should be verified
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
