Utah Road Crash Records for 2020 with Severity and Contributing Factors

UDOT's Crash Studies Team maintains this database of all crashes on Utah public roadways for 2020. The data includes 28 specific fields such as crash severity, involved vehicle types, and contributing factors like distracted or drowsy driving. It was last updated by opendata.utah.gov in February 2021.

Use Cases

• Predict CRASH_SEVERITY_ID from factors like DUI, DISTRACTED_DRIVING, and NIGHT_DARK_CONDITION using classification models.
• Analyze spatial patterns of crashes by clustering points using LAT_UTM_Y and LONG_UTM_X coordinates.
• Identify correlations between road types (ROUTE, MAIN_ROAD_NAME) and specific crash types like ROADWAY_DEPARTURE or OVERTURN_ROLLOVER.
• Assess demographic risk by analyzing crashes involving TEENAGE_DRIVER_INVOLVED or OLDER_DRIVER_INVOLVED across different COUNTIES.
• Model the impact of environmental factors like WILD_ANIMAL_RELATED or WORK_ZONE_RELATED on SINGLE_VEHICLE crash occurrence.

Strengths

• Contains 28 detailed columns covering crash circumstances, severity, location, and contributing factors.
• Includes precise geospatial coordinates (LAT_UTM_Y, LONG_UTM_X) for mapping and spatial analysis.

Limitations

• The dataset's sample size (row count) is unknown, limiting assessment of statistical power.
• Data is restricted to a single year (2020), preventing longitudinal trend analysis.
• Potential for class imbalance in specific crash types like PEDESTRIAN_INVOLVED or MOTORCYCLE_INVOLVED.
