The author examines carefully the country's future energy needs for transportation and finds that air and auto transportation could consume 82 percent of transport energy in 1990. Limitations on petroleum supplies and energy-caused atmospheric pollution may keep this percentage lower, however, and comsumption of fuel per delivered passenger or per delivered ton will assume increasing importance, and here the high-yield systems continue to be the waterways, the pipelines, the railroads, and passenger buses. Highly innovative systems of transportation (hovercraft, helicopters and the SST) produce low yields, and this will likely discourage heavy use of these systems. The evaluation of human propulsion (walking, cycling) and mass transit for urban areas should encourage consideration of these means of travel where possible and feasible.
