North Carolina Work Zone Records With Lane And Impact Data

Archived records of road work zones across North Carolina, organized by individual zone. The data originates from the North Carolina Department of Transportation's WZDx feed and covers a period from October 2019 to August 2024. Records include details on lane closures, event timing, and data source information.

Use Cases

• Predict `vehicle_impact` levels based on `total_num_lanes`, `restrictions`, and `event_type` using classification models.
• Analyze work zone duration and scheduling patterns by modeling `start_date` and `end_date` against `road_names` and `event_status`.
• Map work zone locations and their evolution over time using `road_event_bbox` and `creation_date` for geospatial-temporal analysis.
• Assess data reporting quality by comparing `data_source_update_date` with `road_event_feed_info_update_date` across different sources.

Strengths

• Data spans nearly five years from October 2019 to August 2024, providing longitudinal coverage.
• Includes over 30 specific columns such as `lanes`, `vehicle_impact`, and `workers_present` for detailed event characterization.
• Data is available in both raw feed format and processed, work-zone-centric organization.

Limitations

• Exact row count and dataset size are unknown, making scale assessment difficult.
• Coverage is limited to North Carolina and may not be representative of other regions.
• Data availability depends on the active status of state feeds, leading to potential gaps.
