Performance Analysis of Urban Rail Transit Network
چکیده انگلیسی

With the construction of new lines, urban rail transit network continues to expand. It is beneficial for the smooth operations of urban rail transit network to analyze the network characteristics of different development periods and summarize the law of development. Based on the theory of complex networks, the paper first compares the characteristic values of Beijing urban rail transit plan network and current operating network and the variation of values. The results indicate that some indicators of plan network such as average degree, clustering coefficient and average shortest distance has increased. However, due to expansion of service radius, the network efficiency decreased slightly. Then, aiming at important nodes failure and line failure, the paper compares the network flexibility after node failure and line failure, and calibrates the key nodes in the network. The results show that the node and line failure have smaller impacts on the planning network. The fundamentality of some nodes changes with the network improvement. For current operating network, it is necessary to guarantee the reliability of key nodes.
