文摘Taking “The grade of traffic volume, the standard of carrying and guided transport” as the basic concept, this paper analyzes different UMT systems from the angles of their functions, classification, technical features and natures. Through a comparison between these systems, especially the amount of traffic at different levels and the adaptability of each system, the author draws out an assessment outline for the selection of a system in accordance with the principle of “function, environment, safety and economy”.
