Sound Rating 2020 for High Traffic Lanes Outside Toulouse-Métropole

Geospatial layers materializing noise-affected areas along land transport infrastructure near Toulouse. The data is based on a 2020 prefectural decree that repealed the 2014 order and classifies infrastructure sections into five categories. It was published by the Bureau de Recherches Géologiques et Minières and last updated in January 2022.

Use Cases

• Classify transport infrastructure noise levels based on the five categories defined in the ministerial order.
• Define noise-affected buffer zones for infrastructure sections based on the specified sector widths.
• Assess required acoustic isolation for new sensitive buildings based on their location within noise-affected areas.

Strengths

• Based on a formal 2020 prefectural decree, providing a legal basis for the classifications.
• Materializes noise-affected areas as geospatial layers for mapping and analysis.
• Last updated on 2022-01-11, indicating some level of maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to its focus on Toulouse-Métropole.
