Type A noise maps for the Côte-d'Or road network represent areas exposed to sound levels above 55 dB(A) for the year 2017. The maps use isophone curves with a 5 dB(A) step and the Lden (Day-Evening-Night) noise indicator. The dataset was published by the Bureau de Recherches Géologiques et Minières and last updated in March 2019.
Use Cases
- Assess population exposure to road traffic noise based on Lden indicator levels.
- Model noise pollution impact on urban and rural areas in Côte-d'Or based on isophone curves.
- Support environmental policy and noise mitigation planning for the road network.
Strengths
- Specific geographic coverage for the Côte-d'Or road network.
- Uses the standardized Lden noise indicator with defined weighting for evening and night periods.
- Data is for a specific reference year (2017).
Limitations
- Last updated 2019-03-29 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.
