Noise-Exposed Areas in Haute-Savoie: Nighttime Road Noise Above 50 dB(A)

Areas exposed to noise levels above 50 dB(A) along roads with annual traffic exceeding 3 million vehicles. The dataset contains isophone curves calculated for the night period (22h-6h) using the Ln indicator, produced by the Bureau de Recherches Géologiques et Minières for strategic noise mapping in Haute-Savoie. It was last updated on March 29, 2019.

Use Cases

• Modeling noise pollution exposure for public health studies based on the Ln night noise indicator.
• Assessing compliance with environmental noise regulations based on isophone curves for areas above 50 dB(A).
• Planning urban development and infrastructure to mitigate noise impact based on traffic volume and noise level data.
• Creating strategic noise maps for road infrastructure as mandated by environmental directives.

Strengths

• Data is based on a specific noise threshold (above 50 dB(A)) and traffic volume threshold (exceeding 3 million vehicles/year).
• Noise levels are calculated using a defined indicator (Ln) for a specific time period (22h-6h) with a stated step (5 dB(A)).
• Geographic scope is explicitly defined as the road infrastructure of Haute-Savoie.

Limitations

• Last updated 2019-03-29 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.
