Road Noise Affected Areas in Maine-et-Loire, France

A French departmental map service identifies land sectors impacted by noise from major transport infrastructure, as mandated by national law. The dataset is based on a prefectural classification of roads with over 5,000 vehicles per day, intercity rail lines with over 50 trains daily, and public transport lines with over 100 buses. It was last updated by the Bureau de Recherches Géologiques et Minières on September 3, 2021.

Use Cases

• Modeling noise pollution exposure for new building projects based on the defined affected sectors.
• Assessing compliance with acoustic requirements for construction in areas near classified transport routes.
• Informing local planning documents (PLUs) with the officially designated noise impact zones.
• Analyzing the spatial relationship between high-traffic infrastructure and residential or sensitive areas.

Strengths

• Based on a formal legal framework (French Environmental Code and 1992 law) for noise control.
• Defines specific traffic thresholds (e.g., >5,000 vehicles/day) for infrastructure inclusion.
• Produced by a recognized geological and mining research organization (BRGM).

Limitations

• Last updated 2021-09-03 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific geographic scale are unknown, which may limit suitability assessment.
