Abstract :
A panel convened by the U. S. Department of Commerce Technical Advisory Board in 1966 was asked to survey the technical feasibility of novel modes of high-speed ground transportation (HSGT) systems and recommend research programs necessary for the development of such systems. HSGT systems, for the purpose of the study, were defined as operating in, or on, fixed guideways at intercity cruising speeds of at least 300 mi/h (482.8 km/h). Although present knowledge of the nation´s total future transportation requirements, and of the relative role of HSGT, was judged to be insufficient for a decision to construct such a system, the panel considered the creation of an HSGT system to be technically attainable and recommended a multifaceted research and development program. Specific research areas recommended were those needed to provide data necessary to a decision to construct an HSGT system and to select from among alternative system concepts. Highest priorities were assigned to system simulations and transportation data studies, resolution of the contact versus fluid support question, experimental studies of the aerodynamics of vehicles traveling it tubes at high speeds, development of new tunneling technology, and transfer of electrical energy by contact rails and collectors at HSGT speeds.
