Data & Methodology
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 August 2026 in Galveston County.
The corridor‑level dataset on this page is original work produced by Local Traffic Accidents. We geocode the underlying incidents, match them to the numbered state‑highway system, and compute the per‑corridor crash, fatality, and serious‑injury totals, rankings, concentration shares, and per‑1,000 lethality rates shown here. The raw crash records are TxDOT's; the corridor identification, the derived statistics, and the rankings are our own.
Corridors are ranked by total reported crashes. “Deaths” counts persons killed and “serious injuries” counts persons with suspected serious injuries (the official KABCO “A” level), summed across all crashes on each corridor — not crash counts. This ranking covers the numbered state highway system (Interstates, U.S. and state highways, FM/RM roads, loops, and spurs); locally maintained surface streets are recorded under a separate, free-text field and are not included here. Each route is reported under its primary TxDOT designation; co-signed routes (for example, I-69 and U.S. 59) are noted but not combined.
