摘要：

The resilience of the urban public transport systems was evaluated using a system function curve model to quantify the urban public transport system resilience. The model included the bus and taxi systems with the bus service rate and the taxi online rate used as the system function to evaluate the urban public transport system resilience. This method was then used to evaluate the resilience of the public transport system during the Zhengzhou storm and flooding in 2021. The results show that the Zhengzhou public transport system is moderately resilient and various recovery schemes could affect the recovery capacity and adaptability of the system. The model describes the system functions in stages from the initial disturbance to a new equilibrium state to calculate the urban public transport system resilience. This method is suitable for single disasters and multiple, coupled disasters and can provide guidance for improving the ability of urban public transport systems to deal with unknown disruptions. © 2022, Tsinghua University Press.
