摘要

Since the practical railway systems with steam locomotives originated in the beginning of 19th century, it had played the major part of ground transportation for about one hundred years. On the other hand, automobiles appeared at the end of 19th century and remarkably developed as the important means of transportation during 20th century. At present, both ground transportation means are playing the peculiar part in respective field and more technological developments are necessary to meet social requirements such as global environment protection.
