Major Railway Noise Levels with Day, Evening, and Night Metrics

OpenDataNI provides noise level data for major railways, likely covering the UK. The dataset includes metrics such as Lden, Lnight, Lday, Levening, LAeq,16hr, and LAeq,6hr, which are standard acoustic indicators. It was last updated on 2026-03-18 and is available in multiple formats including CSV, JSON, and geospatial formats like KML and GEOJSON.

Use Cases

• Modeling community noise exposure based on Lden, Lnight, Lday, and Levening metrics.
• Assessing compliance with noise regulations for railway infrastructure.
• Creating geospatial visualizations of noise pollution using the provided KML and GEOJSON files.
• Analyzing diurnal noise patterns using the separate day, evening, and night indicators.

Strengths

• Data is provided under the OGL-UK-3.0 license, facilitating open use.
• Available in multiple formats including CSV, JSON, and geospatial formats (KML, SHP, GEOJSON).
• Includes standard acoustic metrics (Lden, Lnight, Lday, Levening, LAeq) for comprehensive noise 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.
