SELECTION METHOD OF RAILWAY ACCIDENT RISK PREDICTION MODEL CONSIDERING ACCIDENT RESPONSE COST

摘要

A method for selecting a model for predicting a railway accident risk, the method comprising the steps of: dividing a plurality of predicted railway accident risk results into a case of exceeding a preset reference value and a case of less than the reference value; A step of dividing the plurality of actual railway accident risk results corresponding to the plurality of actual railway accident risk results into a case of exceeding the reference value and a case of less than the reference value, Determining the expected accuracy of the railway accident risk prediction model based on the result of the classification of the plurality of predicted railway accident risk results and the classification result of the plurality of actual railway accident risk results, Calculating a predicted cost value and a predicted cost value And it may include the step of selecting a railway accident risk prediction model based on.
