A database defining isophones, or noise contours, for land transport infrastructure during the Ln (night) period. The dataset was published by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated on April 2, 2019. It focuses on departmental and communal roads in the Vendée region of France.
Use Cases
- Modeling nighttime noise exposure for residential areas based on road infrastructure.
- Assessing compliance with environmental noise regulations for specific road segments.
- Planning noise mitigation measures for roads in the Vendée region.
- Studying the relationship between road type and noise propagation levels.
Strengths
- Data is sourced from a national geological and mining research organization (BRGM).
- Focuses on a specific temporal period (Ln/night) for noise measurement.
- Has a defined geographic scope (Vendée, France).
Limitations
- Last updated 2019-04-02 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
