Road Traffic Noise Exposure at Night Along Departmental Road 611 in Deux-Sèvres

Isophone curves map areas exposed to night-time road noise levels starting from 50 dB(A) in 5 dB(A) increments. The data represents the Ln noise indicator, which corresponds to the average sound level during the night period (22h-6h) and is associated with sleep disruption risk. It was produced by the Bureau de Recherches Géologiques et Minières (BRGM) to comply with the European Directive on Strategic Noise Maps.

Use Cases

• Modeling sleep disruption risk based on noise exposure levels (Ln) mentioned in the description
• Assessing compliance with European noise mapping directives based on the represented noise indicators
• Planning noise mitigation measures for specific road corridors based on isophone curve data

Strengths

• Data is structured using isophone curves, a standard method for visualizing noise exposure.
• Complies with the calculation methods and indicators mandated by European Directive 2002/49/EC and French implementing texts.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
