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

Railway noise data from the OpenDataNI organization, last updated on March 18, 2026. The dataset includes noise level metrics such as Lden, Lnight, Lday, Levening, and LAeq for 6, 16, and 18-hour periods. It is licensed under the OGL-UK-3.0 license.

Use Cases

• Modeling long-term community noise exposure based on Lden (day-evening-night) levels.
• Assessing nighttime noise impact on sleep disturbance based on Lnight levels.
• Analyzing daytime and evening-specific railway noise patterns based on Lday and Levening metrics.
• Comparing short-term (6hr) and extended (18hr) equivalent sound pressure levels based on LAeq columns.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq).
• Available in multiple geospatial formats (KML, SHP, GEOJSON).
• Data is licensed under the permissive OGL-UK-3.0 license.

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.
