DDTM-06: Noise Limit Exceedance Map for Major Roads in Alpes-Maritimes

Noise level zones describe noise exposure based on a noise indicator or area affected by noise. The dataset maps exceedance of noise limit values for major road infrastructure in the Alpes-Maritimes department using the Lden (day-evening-night) indicator. It was produced by the Bureau de Recherches Géologiques et Minières and last updated in July 2021.

Use Cases

• Map noise pollution exposure zones based on the Lden noise indicator mentioned in the description.
• Assess compliance with environmental noise limits for major road infrastructure.
• Prepare strategic noise maps for the Alpes-Maritimes region as required by environmental code.
• Analyze spatial patterns of noise exceedance related to transportation networks.

Strengths

• Data is explicitly tied to a legal framework (Article R.572-5 of the Environmental Code).
• The dataset has a specific geographic focus on the Alpes-Maritimes department.
• It was last updated on 2021-07-19, providing a temporal reference point.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2021-07-19 00:00:00; freshness should be verified.
• Column-level documentation is absent; field semantics must be inferred after download.
