Nighttime Road Noise Exposure Areas for RD 950 in Melle, France

Areas exposed to land transport infrastructure noise at night (Ln) are represented using isophone curves drawn in steps of 5 dB(A) starting at 50 dB(A). The data covers the RD 950 route to Saintes on the commune of Melle, France, and was last updated by the Bureau de Recherches Géologiques et Minières on April 4, 2019. The Ln indicator corresponds to the average sound level during the night period (22h-6h) and reflects a notion of overall discomfort or health risk, specifically sleep disruption.

Use Cases

• Assess sleep disruption risk based on the Ln noise indicator for the night period.
• Model noise exposure zones using isophone curves drawn in 5 dB(A) steps.
• Support strategic noise mapping for the RD 950 route as required by EU directives.
• Analyze geographic areas exposed to land transport noise levels exceeding 50 dB(A) at night.

Strengths

• Data is structured as geospatial isophone curves with a defined noise level step of 5 dB(A).
• Focuses on a specific noise indicator (Ln) for the night period (22h-6h) linked to health risk.
• Complies with calculation methods mandated by the European Directive on Strategic Noise Maps.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
