Line, Network and System of Urban Rail Transit

According to the different patterns of URT (urban rail transit) construction, its development process can be divided into three stages: the line construction, the network construction and the system construction. From the point of physical meaning and systematic functions, this paper gives a theoretical analysis of and an interpretation for the "line", "network", and "system" of URT. Base on the analysis and discussion of these construction patterns, this paper points out that the system construction is becoming the trend of URT development in China, and further analyzes the key steps in the implementation of the system construction. The author also indicates the characteristics of the system construction of URT from aspects of systematic technology, resource utilization, construction management and construction conditions. Finally, this paper concludes that the system construction can fully embody the concept of "safe metro, efficient metro, scientific metro, green metro, human-oriented metro and workable metro", which can greatly enhance the quality of URT system in China.
