The Texas Transportation Institute (TTI) is a department at Texas A&M University that researches the safety and efficiency of vehicles, roads, and rails. The institute acts as an official agency of the Texas Department of Transportation and the Railroad Commission of Texas, and it coordinates with other similar government agencies around the United States.

Most of the institute's research is on the safety of cars and highways. Several innovations have come out of TTI, including the slip base for highway signs and special endcaps for guardrails that reduce the collisison injuries.

The TTI was created in 1950 and has become the largest university-affiliated research agency in the country. Its research receives regular media attention due to its annual Urban Mobility Study, which provides data on traffic congestion in major U.S. cities.
