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

OpenDataNI provides this dataset on railway noise pollution, featuring acoustic metrics like Lden, Lnight, Lday, Levening, and LAeq for 16-hour, 6-hour, and 18-hour periods. The data is available in multiple formats including JSON, KML, CSV, SHP, and GEOJSON. It was last updated on 2026-03-18.

Use Cases

• Modeling community noise exposure based on Lden (day-evening-night) levels.
• Assessing nighttime noise disturbance from railways using Lnight metrics.
• Mapping noise pollution from rail transport using the provided geospatial file formats.
• Analyzing daytime versus evening noise levels using the Lday and Levening columns.

Strengths

• Includes multiple standardized noise metrics (Lden, Lnight, Lday, Levening, LAeq).
• Available in several interoperable formats (JSON, KML, CSV, SHP, GEOJSON).
• Released under the OGL-UK-3.0 license for open use.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to uk_data.
