Strategic noise maps for the Eure road network in France, developed under EU Directive 2002/49/EC. The data shows areas exposed to more than 55 dB(A) in Lden (Day-Evening-Night Level) and more than 50 dB(A) in Ln (Night Level). Maps were produced by the Bureau de Recherches Géologiques et Minières and approved in November 2018, representing the third assessment deadline in 2017.
Use Cases
- Modeling population exposure to transport noise based on defined Lden and Ln indicators.
- Assessing compliance with EU noise directive thresholds for major road infrastructure.
- Planning noise mitigation strategies for areas exceeding 55 dB(A) during daytime periods.
- Analyzing spatial patterns of noise pollution along a specific regional road network.
Strengths
- Data is produced under a specific EU directive (2002/49/EC), providing a standardized legal framework.
- Maps use defined acoustic indicators (Lden and Ln) with explicit time period definitions (Day: 6h-18h, Evening: 18h-22h, Night: 22h-6h).
- Approved by a prefectural order dated November 16, 2018, indicating an official review process.
Limitations
