Research and implementation on connectivity reliability calculation algorithm of urban rail transit network operation

This paper focuses on reliability calculation algorithm of urban rail transit network operation. First, the definition of network operation reliability is imported. Considering the network topology, passenger flow in and out of the station, the section passenger flow and other factors, we propose four network operation connectivity reliability indicators, such as betweenness centrality structure entropy, the Gini coefficient of station passenger flow and so on, which reflect different aspects of the connectivity reliability, and finally gives weight for indicators based on rank correlation analysis, and calculates the connectivity reliability. Taking Beijing urban rail transit as an example, use MATLAB and PAJEK to calculate the model under the passenger flow at different times, the results show that flat peak connectivity reliability is above the morning and evening peak level, and have a better agreement with the reality.
