Noise Maps for National Roads in Landes, France: Nighttime Zones Exceeding 62 dB

The Department of Landes in France produced noise maps in 2008 in response to European Directive 2002-49 and a 2006 French decree. The dataset identifies zones along major road and motorway networks where nighttime noise levels exceed 62 decibels. It was created by the Bureau de Recherches Géologiques et Minières and last updated in September 2021.

Use Cases

• Assess compliance with EU noise regulations based on harmonized noise level indicators.
• Model noise exposure for populations near major roadways based on mapped noise zones.
• Plan noise mitigation strategies for infrastructure like the A63, A64, and RN10 roads mentioned.
• Analyze the spatial correlation between high-noise zones and specific road networks.

Strengths

• Based on a specific legal framework: European Directive 2002-49 and French Decree No. 2006-361.
• Uses harmonized noise indicators: Lden and Ln, with specific thresholds of 68 dB(A) and 62 dB(A).
• Clearly defines the geographic scope: the Department of Landes and specific road axes like A63, A64, and RN10.

Limitations

• Data is from a single snapshot year (2008); freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file formats are unknown, which may limit suitability assessment.
