Railway Noise Levels in Agglomerations: Day, Evening, and Night Metrics

A dataset from OpenDataNI, last updated on 2026-03-18, containing railway noise measurements. It likely includes acoustic indicators such as Lden (day-evening-night level), Lnight, and LAeq for 18-hour, 16-hour, and 6-hour periods. The data is provided in multiple geospatial and tabular formats including SHP, GEOJSON, KML, and CSV.

Use Cases

• Modeling long-term noise exposure (Lden) for health impact studies based on day, evening, and night periods.
• Assessing nighttime noise disturbance (Lnight) for sleep quality research near railways.
• Analyzing daytime-specific noise levels (Lday) for urban planning and zoning regulations.
• Comparing noise levels across different time windows (LAeq,16hr, LAeq,6hr, LAeq,18hr) for operational analysis.

Strengths

• Data is provided in multiple interoperable formats including SHP, GEOJSON, KML, CSV, and JSON.
• Includes several standardized acoustic metrics (Lden, Lnight, Lday, LAeq) for detailed analysis.
• Released under the OGL-UK-3.0 license, facilitating open use and redistribution.

Limitations

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