Noise Zone of the Paris-Le Havre Rail Line: Strategic Night Noise Map (Type C)

European Directive 2002/49/EC mandates strategic noise mapping for major transport infrastructure. This dataset, created under the authority of the Prefect of the Department, represents areas where night noise levels (Ln index) exceed 65 dB(A) along the Paris-Le Havre rail line. The map was approved in November 2018 and last updated on 2019-04-03 by the Bureau de Recherches Géologiques et Minières.

Use Cases

• Identify residential areas exceeding legal noise limits based on the Ln (night level) index.
• Analyze the spatial impact of rail traffic noise based on the defined noise-exposed areas (Type C map).
• Support environmental impact assessments for infrastructure projects based on the strategic noise mapping methodology.
• Monitor compliance with EU noise regulations over time based on the 5-year review cycle mentioned.

Strengths

• Based on a defined regulatory framework (EU Directive 2002/49/EC) with specific noise indicators (Lden, Ln).
• Has a formal approval date (November 16, 2018) and a clear last update timestamp (2019-04-03).
• Defines specific noise threshold values for classification (Ln > 65 dB(A), Lden > 73 dB(A)).

Limitations

• Last updated 2019-04-03 00:00:00; freshness should be verified against the 5-year review cycle.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
