TR News March-April 2018: Test Track for New Tech

Already in use in the construction industry, 3-D printing technology can change the way transportation infrastructure is designed, constructed, and maintained. Author Mohammad Khan examines the history and progress of 3-D printing and automated construction and the applications of these technologies to transportation. Also presented are insights from the development of Hyperloop One, a commercial travel prototype consisting of a levitation system; propulsion, power, and electronics systems; controls; vacuum structures; and an autonomous pod—as well as a vision for the future of intercity travel. Other articles offer an overview of the work of the Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine, and a look at the 2018 TranspoCamp event, an “unconference” that convenes researchers and practitioners interested in urban transportation and technology. TR News 314: March–April 2018 also includes photos from the TRB 97th Annual Meeting in January.
