Road Noise Exposure Areas for Niort-Parthenay Route at Night

BUREAU DE RECHERCHES GÉOLOGIQUES ET MINIÈRES provides data on areas exposed to road traffic noise at night along departmental road 743 from Niort to Parthenay in Deux-Sèvres, France. The data represents noise exposure using isophone curves in 5 dB(A) steps starting from 50 dB(A) for the Ln indicator, which measures average sound levels between 10 PM and 6 AM. This dataset was last updated on April 4, 2019, and is produced in compliance with the European Directive on Strategic Noise Maps.

Use Cases

• Mapping sleep disruption risk zones based on night-time noise exposure levels (Ln).
• Assessing compliance with EU noise directive indicators for strategic noise mapping of land transport.
• Modeling population exposure to road traffic noise using isophone curve data.
• Planning noise mitigation measures for specific road corridors based on dB(A) contours.

Strengths

• Data is structured around a specific noise indicator (Ln) defined for the night period (22h-6h).
• Noise levels are represented using standardized isophone curves drawn in steps of 5 dB(A).
• Dataset is tied to a specific legal framework (European Directive on Strategic Noise Maps and French Environmental Code).

Limitations

• Last updated 2019-04-04 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Spatial and temporal coverage is limited to a single road segment and a specific update period.
