Comparative study on security risk assessment methods for high-speed railway stations
Various public health risks such as epidemics outbreaks still exist,so it is necessary to compare,study and summarize the experience of the security risk assessment methods for high-speed railway stations under similar emergency events,in order to serve decision-making of public safety management better.In the case study,five methods including the AHP,risk index method,risk matrix method,neural network method,and the Delphi method were used to evaluate the risk for the Z station,and all the evaluation process and results were compared and analyzed.Research has found that all methods except the AHP can achieve risk assessment tasks and the results are convergent,but the risk index method is the most preferred due to its high accuracy and low resource requirements.It is particularly suitable for assessing security risks in emergency events.In addition,different evaluation methods have different focuses and result forms,and it is recommended to use them comprehensively according to their respective characteristics.The conclusion of the study can provide useful reference for public safety management for high-speed railway stations.In the future,further research should be conducted on the construction of a universal indicator system to enhance its applicability to various environments and improve the accuracy of evaluation results.
