High Accident Intersections in Dallas from 2015 to 2019

Traffic intersections in Dallas with 50 or more reported accidents over a five-year period. The dataset includes counts for accidents, injuries, and fatalities per intersection. Data was published by the City of Dallas and last updated in August 2021.

Use Cases

• Identify intersections for safety interventions by ranking locations based on ACCIDENT_CNT and INJURY_CNT.
• Analyze the correlation between DEATH_CNT and specific street pairs (STREET_NAME, STREET_NAME_2) to understand fatal collision patterns.
• Allocate public safety resources by mapping high-crash intersections against Council Districts--Test or the Dallas City Limits GIS Layer.
• Perform geospatial clustering of accident hotspots using the GeoReference field for each intersection.

Strengths

• Filters to intersections with a significant minimum of 50 accidents, focusing analysis on high-risk locations.
• Includes multi-year aggregated data covering the period from 2015 through 2019.
• Provides key severity metrics per row: ACCIDENT_CNT, INJURY_CNT, and DEATH_CNT.

Limitations

• Row count and total dataset size are unknown, limiting assessment of statistical power.
• Data is temporally stale, covering events only up to 2019 with no updates since 2021.
• Lacks granular temporal data (e.g., time of day, month) and causal details (e.g., weather, vehicle type).
