Abstract:

Urban rail transit transfer station failure can lead to network degradation and make the urban rail transit system performance vulnerable. Network vulnerability analysis under transfer station failure is of significance to guarantee operational safety. Considering the coupling relation between urban rail transit networks and external public transport networks, generalized passenger travel cost under transfer station failure is analyzed and passenger travel choice behavior is modelled. From the perspective of the operation service network degradation, the measurement indicator of network vulnerability is developed to quantify the influence of the failure. The urban rail transit topology structure network is modelled, and a vulnerability analysis framework of urban rail transit network is established. A case study on Shenzhen urban rail transit network is conducted; the results show that the vulnerability performance and passenger flow differ for different transfer station failures. Network vulnerability analysis can help managers identify the key transfer stations and devise pertinent emergency strategies.

Key words: urban rail transit, transfer station failure, network vulnerability, passenger travel choice, generalized travel cost
