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

Noise level measurements for major railways, likely in the UK, provided by OpenDataNI. The data includes acoustic metrics such as Lden, Lnight, Lday, Levening, LAeq,16hr, and LAeq,6hr. The dataset was last updated on 2026-03-18 and is available in multiple formats including CSV, JSON, and geospatial files.

Use Cases

• Modeling community noise exposure based on railway sound level metrics.
• Assessing compliance with environmental noise regulations using Lden and Lnight indicators.
• Creating noise pollution maps for urban planning based on geospatial data formats.
• Analyzing diurnal noise patterns using separate day, evening, and night measurements.

Strengths

• Includes multiple standardized acoustic metrics (Lden, Lnight, Lday, Levening, LAeq).
• Available in several interoperable formats including CSV, JSON, and geospatial files (KML, SHP, GEOJSON).
• Data is licensed under OGL-UK-3.0, allowing for open use and redistribution.

Limitations

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