Historical Chicago Pothole Reports and Repair Status

311 Service Requests - Pot Holes Reported - Historical contains records of pothole reports and repairs managed by the Chicago Department of Transportation. The dataset includes all open and completed requests since January 1, 2011, and is updated daily. It is a historical record maintained by data.cityofchicago.org, with its function replaced by a newer dataset.

Use Cases

• Predict SERVICE REQUEST STATUS from CREATION DATE, ZIP, and COMMUNITY AREA using time-series classification.
• Analyze spatial clusters of potholes using LATITUDE and LONGITUDE coordinates for resource allocation.
• Model repair completion time (COMPLETION DATE - CREATION DATE) against features like WARD and NUMBER OF POTHOLES FILLED ON BLOCK.
• Identify duplicate request patterns (STATUS of 'Duplicate (Open)') based on STREET ADDRESS proximity rules.
• Correlate seasonal pothole reporting volume (CREATION DATE) with COMMUNITY AREAS for maintenance planning.

Strengths

• Temporal coverage spans from January 1, 2011 onward, providing over a decade of data.
• Includes multiple geographic identifiers per record: LATITUDE, LONGITUDE, WARD, COMMUNITY AREA, and ZIP CODES.

Limitations

• Dataset is historical-only and was replaced by a newer source, indicating it is not the current operational view.
• Sample data and total row count are unavailable, preventing assessment of dataset scale.
