Road Noise Exposure at Night (Ln) for RD 950 in Melle, France

Geospatial data representing areas exposed to road traffic noise at night (Ln) along departmental road RD 950 in Melle, France. The data was produced by the Bureau de Recherches Géologiques et Minières (BRGM) to comply with the European Directive on Strategic Noise Maps. It uses isophone curves in 5 dB(A) steps starting from 50 dB(A) to map the average sound level during the night period (22:00-06:00), which is associated with sleep disruption risk.

Use Cases

• Modeling sleep disruption risk based on noise exposure levels (Ln) mentioned in the description.
• Assessing compliance with the European Directive on Strategic Noise Maps for land transport infrastructure.
• Visualizing noise pollution isophone curves for a specific road segment (RD 950) in a municipal area.
• Analyzing the spatial distribution of noise levels at night for environmental impact studies.

Strengths

• Data is structured according to the European Directive on Strategic Noise Maps, ensuring a standardized methodology.
• Noise levels are represented using isophone curves with a defined step of 5 dB(A), providing a clear spatial gradient.
• The specific source (RD 950 road) and location (commune of Melle) are clearly identified.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Row count and file size are unknown, which may limit suitability assessment.
