Road Traffic Noise Exposure Areas at Night in Deux-Sèvres, France

Deux-Sèvres, France, contains geospatial data representing areas exposed to road traffic noise at night (Ln). The dataset was produced by the Bureau de Recherches Géologiques et Minières and last updated on April 4, 2019. It visualizes noise exposure using isophone curves in 5 dB(A) steps starting from 50 dB(A), based on the European Directive on Strategic Noise Maps.

Use Cases

• Mapping noise pollution zones based on isophone curves mentioned in the description
• Assessing health risks from sleep disruption based on the Ln noise indicator
• Evaluating compliance with EU noise directive requirements for strategic noise mapping
• Analyzing the impact of specific road routes (e.g., route de la Rochelle) on nighttime noise levels

Strengths

• Based on the European Directive on Strategic Noise Maps, providing a standardized framework
• Noise levels are represented in specific 5 dB(A) increments starting from 50 dB(A)
• Explicitly covers the night period (22h-6h) for the Ln indicator

Limitations

• Last updated 2019-04-04 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
