The largest university-based transportation research institute in the state, with more than 75 years of work on traffic safety and crash analysis. TTI produces the deepest research-grade analysis of Texas roadways available — the source to reach for when a question goes beyond counts into causes and countermeasures.
As academic work, TTI publications are link-out only.
Best for: research-grade depth — why crashes happen and what reduces them, rather than how many occurred.
