Pennsylvania crash data reported to the state Department of Transportation from 1997 onward. The dataset includes details on drivers, passengers, and vehicles for researching highway safety, with specific flags for drug and alcohol involvement. Data may be incomplete, as some elements can be unknown and non-reportable crashes are excluded.

Use Cases

• Assessing the impact of aggressive driving behaviors by correlating Aggressive Driving and Speeding columns with Injury Count.
• Evaluating the severity of crashes involving specific vehicle types like Motorcycle or Hazardous Truck using the Injury Count and Vehicle Towed columns.
• Investigating demographic risk factors by examining crash involvement for age groups like Driver 75 Plus and 19 Year Old Driver Count.

Strengths

• Includes specific flags for drug and alcohol impairment (e.g., DRUG_RELATED, IMPAIRED_DRIVER) relevant for public health research.
• Provides geographic breakdown via Geographic Location of the Crash and District Code columns for county-level analysis.
• Covers a long temporal range from 1997 to the present, allowing for longitudinal studies.
