Research on the Formation Mechanism of Metro Emergency: A Case Study of Rear-End Accident on Shanghai Subway Line 10

摘要

By exploring the formation mechanism of metro emergencies, theoretical support is offered for the prevention and management of emergencies. Using a case study of rear-end accident on Shanghai metro line 10, this paper introduces the Tropos goal risk framework to model the chain of risk transmission in the subway system. On the basis of the model, the emergencies' formation mechanism is researched by analysing the specific conditions and path of risks transmission and development into the emergency. Then the countermeasures to mitigate risks are proposed in order to prevent the risks from becoming the emergency. And theoretical support and methodological guidance are thereby provided for subway emergency management.
