A 2016 noise classification for land transport infrastructure in France's Sarthe department, approved by a prefectural decree on March 18, 2016. It categorizes roads, railways, and public transport lanes based on generated noise levels to determine zones requiring reinforced building insulation. The dataset was produced by the Bureau de Recherches Géologiques et Minières and last updated in April 2019.
Use Cases
- Identify noise pollution zones for urban planning based on infrastructure categories.
- Assess building insulation requirements based on the determined sound footprint.
- Model traffic and train noise propagation using criteria like annual average daily traffic and percentage of heavy goods vehicles.
Strengths
- Classification is based on specific, documented criteria including traffic volume (>5000 vehicles/day) and train frequency (>50-100 trains/day).
- Defines five distinct noise categories with corresponding impact zones ranging from 10 to 300 meters.
- Dataset has a clear authoritative origin from a prefectural decree and a known organization (BRGM).
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download.
- Last updated 2019-04-01 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
