Agglomeration Railway Lden: Railway Noise Pollution Metrics for UK Agglomerations

Railway noise pollution data for UK agglomerations, measured using the Lden (day-evening-night) indicator and other acoustic metrics. The dataset is provided by OpenDataNI under the OGL-UK-3.0 license and was last updated on March 18, 2026. Available file formats include JSON, KML, CSV, SHP, and GEOJSON, suggesting a strong geospatial component.

Use Cases

• Modeling community noise exposure based on Lden, Lday, Levening, and Lnight metrics.
• Assessing compliance with noise regulations using LAeq,16hr and LAeq,6hr indicators.
• Creating geospatial visualizations of railway noise pollution across UK agglomerations.
• Analyzing temporal noise patterns by comparing day, evening, and night sound levels.

Strengths

• Data is provided under the permissive OGL-UK-3.0 license.
• Multiple geospatial file formats (KML, SHP, GEOJSON) are available for analysis.
• Includes multiple standardized noise metrics (Lden, LAeq,16hr, etc.) for detailed assessment.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
