Abstract
Based on graph theory and complex network theory, this paper puts forward macro characteristic indexes of urban rail transit network from three aspects of network development level, network form and structure efficiency. Taking the rail transit network of four stages in Chengdu as an example, and comparing the rail transit network of 11 domestic case cities, the evolution characteristics of Chengdu network structure are analyzed. The results show that the network in the four stages is becoming more and more complex and mature. In the first stage, the network structure is simple and belongs to "auxiliary" network. In the second stage, it will surpass the "backbone type" and reach the level of "main body type", which is equivalent to the first tier cities in China. In the third stage, the development is basically mature with a high network level, and the complexity and connectivity surpass Tokyo, reaching the international leading level. In the fourth stage, the network is more mature and efficient, which supports the urban development.
