Type A noise exposure maps for the road network of Côte-d'Or, France, for the year 2017. The maps represent areas exposed to more than 55 dB(A) using the Lden indicator, displayed as isophone curves with a 5 dB(A) step. The data was published by the Bureau de Recherches Géologiques et Minières (BRGM) and last updated in March 2019.
Use Cases
- Modeling population exposure to road traffic noise based on Lden indicator contours.
- Assessing compliance with noise regulation thresholds for the Côte-d'Or region.
- Planning noise mitigation measures along specific road corridors based on isophone curves.
- Analyzing the spatial distribution of noise pollution from the road network for environmental health studies.
Strengths
- Covers the entire road network of the Côte-d'Or department.
- Provides noise levels for distinct day, evening, and night periods using the standardized Lden indicator.
- Data is represented as isophone curves with a defined 5 dB(A) step for granular analysis.
Limitations
- Data is from 2017; freshness should be verified for current applications.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
