Transportation, whether measured in ton-miles, vehicle-miles or passenger-miles— is consumed. It cannot be stockpiled or accumulated. Each day’s transportation total is gone forever and each new day will provide new demands. Thomas H. MacDonald
Chief, Bureau of Public Roads, 1919 – 1953, and one of the early leaders of TTI
The legacy of the Texas A&M Transportation Institute (TTI) is about a team of researchers in pursuit of a better way to develop and maintain a safe and efficient transportation—saving lives, time and resources.
