Abstract
Urban rail transit is an important part of public transport,and it is an important responsibility of urban rail transit industry to ensure safe and orderly operation.In view of the strong subjectivity and lack of objective data support in many models studying the operation safety of urban rail transit,the structural equation model(SEM)combined with cloud model(CM)is introduced to construct the evaluation model of urban rail transit operation safety,and the evaluation index system is constructed from four aspects:facilities and equipment,management,human factors and natural environment.Through SPSS,Amos software use structural equation to test the reliability and validity of each index data and analyze the fitness,dig out the important characteristics of the data and get the corresponding weight.Then,calculate the digital characteristics of the cloud model of each index,use the Matlab software to draw the cloud picture,and compare the results.Taking Guiyang urban rail transit as an example,the final conclusion shows that the model can better eliminate subjectivity,which is consistent with the actual operation of the example.关键词
