Agglomeration Railway Noise: Day, Evening, and Night Levels

Railway noise exposure data for agglomerations, measured using Lden, Lnight, Lday, Levening, and LAeq metrics. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated on 2026-03-18. It is available in multiple geospatial and tabular formats including JSON, KML, CSV, SHP, and GEOJSON.

Use Cases

• Modeling community noise exposure based on Lden, Lnight, Lday, and Levening indicators.
• Assessing compliance with noise regulations using LAeq,16hr, LAeq,6hr, and LAeq,18hr measurements.
• Creating noise pollution maps for urban agglomerations based on the provided geospatial formats.
• Analyzing temporal noise patterns (day, evening, night) from railway operations.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq).
• Data is available in several interoperable formats, including geospatial (KML, SHP, GEOJSON) and tabular (CSV, JSON).
• Published under the permissive OGL-UK-3.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial/temporal coverage are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the uk_data platform.
