About This Data
The underlying crash records come from the Texas Department of Transportation's Crash Records Information System (CRIS), the official statewide record of reported traffic crashes, covering January 2020 through September 2026 across the 13-county region (1,193,182 total crashes).
The county and corridor rankings are original work produced by Local Traffic Accidents. We geocode the underlying incidents, match them to the numbered state-highway system (Interstates, U.S. and state highways, FM/RM roads, loops, and spurs), and compute the per-county and per-corridor crash, fatality, and serious-injury totals and rankings shown here. The raw crash records are TxDOT's; the geocoding, the derived statistics, and the rankings are our own. Figures update as new records are released by the state.
