RATP Railway Noise Classification in Paris, 2019

Approved by Prefectural Order No. 75-2019-10-03-003 on 3 October 2019, this dataset contains the sound classification of RATP railway infrastructure in the Paris department. It segments overhead railway lines into homogeneous sections and assigns them a noise category from 1 to 5, where a higher number indicates a lower assumed noise level at the infrastructure edge. The data is provided by the Bureau de Recherches Géologiques et Minières (BRGM) and was last updated on 7 October 2019.

Use Cases

• Modeling noise exposure for residential areas based on railway line classification.
• Analyzing the spatial distribution of noise pollution from public transport infrastructure.
• Supporting regulatory compliance and environmental impact assessments based on the classification mandated by the Environmental Code.

Strengths

• Classification is based on a specific legal framework (Articles R157-32 to 43 of the Environmental Code).
• Data has a precise approval date (3 October 2019) and a clear geographic scope (Paris department).
• The noise classification uses a defined ordinal scale from 1 to 5.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Last updated 2019-10-07 00:00:00; freshness should be verified.
• Data coverage is limited to overhead railway lines, excluding covered or tunneled sections.
