Research on risk assessment method of subway driver driving fatigue based on AHP-FCE

Abstract

Subway driver is one of the important factors in the "man-machine-environment" system of subway driving safety, which is of great significance to the safe operation of rail traffic. Based on the fatigue generation mechanism and previous experimental data, this paper establishes a risk assessment index system for subway driver driving fatigue including four elements: physiological, psychological, management and environmental factors based on systematic analysis of possible risks and influencing factors of driving fatigue. The Analytic Hierarchy Process (AHP) and Fuzzy Comprehensive Evaluation (FCE) were organically combined to establish a driving fatigue risk assessment model for subway drivers and obtain the driving fatigue risk level of subway drivers. Finally, through the case evaluation of a single driver on the main line of an existing operation line, it is found that the risk level of driving fatigue of the subway driver is general risk, and the AHP-FCE model has good adaptability and rationality, which has good application value for the study of driving fatigue of subway drivers.
