Texas Highway Work Zone Lane Closures and Events

Archived lane closure occurrences within the Texas Department of Transportation highway system from October 2019 to August 2024. The data is provided in a tabular format by the ITS Joint Program Office, with raw and processed versions organized by work zone.

Use Cases

• Analyze traffic impact by correlating `vehicle_impact` and `lanes` with `start_date` and `end_date` for specific `road_name` segments.
• Assess work zone duration and scheduling efficiency using `start_date`, `end_date`, and `event_status` fields.
• Map work zone locations and geometries for spatial analysis using the `geometry_linestring` or `geometry_multipoint` columns.
• Study safety conditions by examining the frequency of `workers_present` flags alongside `reduced_speed_limit` and `restrictions` data.
• Track data provenance and update cycles via `road_event_feed_info_feed_update_date` and `road_event_feed_info_version`.

Strengths

• Covers a multi-year period from October 2019 to August 2024.
• Includes over 25 specific columns detailing work zone attributes, geometry, and metadata.
• Provides both raw feed data and processed data organized by individual work zone.

Limitations

• Exact row count and dataset size are unknown.
• Geographic coverage is limited to the Texas Department of Transportation highway system.
• Data availability depends on the active feed period for each state, leading to potential temporal gaps.
