| 摘要： | In many areas of the country, congestion on the interstate and rural transportation network is significant, with billions of dollars a year in lost productivity associated with this congestion. In addition, it is predicted that the number of cars and trucks on the road will quadruple by the 2050 and it is clear that the current interstate and rural transportation network cannot currently handle such volume efficiently (i.e., without even more significant delays in transit). These growth predictions are used by many public planners to advocate for high-speed passenger rail systems, which are generally defined as systems where the trains travel in excess of 100 mph. However, in countries like Germany and Japan, magnetic levitation trains (i.e., Maglev trains, which are single-car trains that are levitated above rail via magnetic fields for nearly frictionless travel) are being used effectively for such purposes at very high speeds. For example, the Yamanashi Maglev Test Line in Japan runs 42.8 km between Sakaigawa and Akiyama, achieving a top speed of 500 kph. With top speeds predicted to increase in the future by 60%(up to 500 mph), we ask why not explore this technology and other high-speed rail technologies in the U.S. for freight transportation. Due to the predicted 10x speed advantage, such a network would be commercially attractive for freight distribution, especially for 'truckload' distribution, even on a network that is significantly smaller than the current interstate highway. And if such a network is well-utilized, highway congestion and its associated costs and negative impacts would be significantly reduced. This project will lead to a better understanding of high-speed rail technologies in terms of technological feasibility, network design, and infrastructure challenges, including the design and operation of crossdock facilities for freight transfer in the resulting inter-modal network. / NOTE: Final rept. / Supplementary Notes: Prepared in cooperation with Arkansas Univ., Fayetteville.
