of this study is to block the formation of cascading accident networks by identifying and preventing
critical hazards. A modified five-step task-driven method (FTDM) is proposed to break down
passenger-related cascading escalator accidents. Three complex network parameters in complex
network theory are utilized to identify critical and non-critical Risk Passenger Behavior (RPB) hazards
and Other Hazards related with Risk Passenger Behavior (OH-RPB) in accident chains. A total
of 327 accidents that occurred in the Beijing metro rail transit (MRT) stations were used for case
studies. The results are consistent in critical and non-critical RPB and OH-RPB and prove that through
combination of FTDM accident investigation model and complex network analysis method, critical
and non-critical RPB and OH-RPB in a complicated cascading hazards network can be identified.
Prevention of critical RPB can block the formation of cascading accident networks. The method not
only can be used by safety manager to make the corresponding preventive measures according to
the results in daily management but also the findings can guide the allocation of limited preventive
resources to critical hazards rather than non-critical hazards. Moreover, the defects of management
plan and product design can be re-examined according to the research results.
