Road Noise Exposure Areas at Night for Helensburgh Boulevard in Thouars

Areas exposed to road traffic noise at night (Ln) for Helensburgh Boulevard in Thouars, France, represented by isophone curves in 5 dB(A) steps from 50 dB(A). The data is produced by the Bureau de Recherches Géologiques et Minières (BRGM) to comply with the European Directive on Strategic Noise Maps, last updated in April 2019. The Ln indicator isolates the night period (22h-6h) and is associated with the risk of sleep disruption.

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 based on the provided noise indicators.
• Visualizing noise pollution contours (isophone curves) for land transport infrastructure at night.
• Analyzing the geographic distribution of noise exposure from a specific road (Helensburgh Boulevard).

Strengths

• Data is structured according to the European Directive on Strategic Noise Maps, providing standardized noise indicators (Lden and Ln).
• Noise levels are represented using isophone curves drawn in specific 5 dB(A) intervals, starting at 50 dB(A).
• The dataset is associated with a specific legal framework (Articles L572-1 to 11 of the French Environmental Code).

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.
