Investigation of Design Standards for Urban Rail Transit Elevated Structures

摘要

During the past decade, mass or public transportation has received an increase in attention as a viable transportation mode within highly urbanized areas. This increase in recognition of the mass transit mode of moving people, largely came about as a result of congestion of cars on urban highways and streets. At about the same time as automobile congestion was becoming critical, organized opposition to construction all but stopped cities from relieving their transportation problems. It was these events that prompted urban communities to look at alternate transportation modes, such as elevated rail transit systems. The purpose of this report was to review the various criteria for design of elevated rail transit structures currently in use by selected transit properties and to determine the feasibility of industrywide guidelines for their design, and to compile them in one source.
