Chicago Traffic Crash Person-Level Data with Injury and Safety Details

Person-level records for individuals involved in traffic crashes in Chicago, including vehicle occupants, pedestrians, and bicyclists. The data is reported by the Chicago Police Department using the IL Traffic Crash Reporting form SR1050 and can be linked to crash and vehicle records. Fatalities are updated up to 30 days after the crash date.

Use Cases

• Classify injury severity (INJURY_CLASSIFICATION) based on safety equipment (SAFETY_EQUIPMENT), age (AGE), and crash dynamics (AIRBAG_DEPLOYED, EJECTION).
• Analyze driver action (DRIVER_ACTION) and physical condition (PHYSICAL_CONDITION) in relation to BAC test results (BAC_RESULT).
• Profile pedestrian and bicyclist incidents using PEDPEDAL_ACTION, PEDPEDAL_LOCATION, and PEDPEDAL_VISIBILITY columns.
• Link person records to vehicle and crash events using the CRASH_RECORD_ID and VEHICLE_ID fields for multi-table analysis.

Strengths

• Includes 30 distinct columns covering demographic, behavioral, injury, and situational factors for each person.
• Designed for linkage with companion Crash and Vehicle datasets via the CRASH_RECORD_ID field.
• Data follows a standardized reporting form (SR1050) with a publicly available instruction manual.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Injuries are reported by the responding police officer, not a medical professional.
• The RD_NO (police report number) was removed for privacy, which may affect certain linkage or validation tasks.
