Nighttime Road Noise Exposure (Ln) for Avenue Saint-Jean d’Angély in Niort

Deux-Sèvres, France, areas exposed to land transport noise at night (Ln) are represented using isophone curves in 5 dB(A) steps from 50 dB(A). The data was published by the Bureau de Recherches Géologiques et Minières (BRGM) on 2019-04-04 to comply with the European Directive on Strategic Noise Maps. It models the average sound level during the night period (22h-6h) for the Avenue Saint-Jean d’Angély in Niort.

Use Cases

• Modeling population exposure to nighttime traffic noise based on isophone curves.
• Assessing compliance with EU noise regulations for strategic noise mapping.
• Identifying zones exceeding specific noise thresholds for health risk studies.
• Visualizing spatial distribution of noise pollution from a specific road segment.

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 (Avenue Saint-Jean d’Angély) and noise indicator (Ln for night period) are clearly identified.

Limitations

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