2017 Letter from the former Director
I am pleased and proud to present this annual report. It summarizes the activities and accomplishments of the Center for Transportation Research during our 45th Anniversary year at the University of Tennessee. In this span of five decades, CTR has become an internationally recognized center of innovation, with more than $10 million in sponsored research under contract. CTR plays a critical role in the Tickle College of Engineering’s training of Tennessee’s future transportation professionals.
How Tennessee can become a hub for transportation innovation
Tennessee currently supports 40 percent of the EV manufacturing jobs and investments in the southeast, but ranks 41st in the country for industrial R&D. As transportation evolves, and the focus on car travel shifts from the combustion engine to the electric battery, Tennessee is already a key player in the world of manufacturing. Ford, GM, […]
