On The Relationship Between Work Stress And Safety Performance Of Train Drivers

The rapid development of Chinese railway, the substantial improvement in technological level and more complicated operation environment lead to the work stress of train driver, and the work stress has a great influence on the safety of train driver. In order to improve the safety performance of the train driver as well as to ensure the safe operation of railway, this thesis selects the train driver as the studies object and study the relationship between the work stress of train driver and safety performance.The main content of study on the relationship between the work stress of train driver and safety performance:(1) literature review on the work stress and safety performance;(2) research ideas, research hypothesis and theoretical model on the relationship between the work stress of train driver and safety performance;(3) questionnaire design and quality analysis of survey data on the relationship between the work stress of train driver and safety performance; and (4) the collected data based on the questionnaire as well as the verification and analysis on the model and research hypothesis on the relationship between the work stress of train driver and safety performance.Study results are as follows:(1) obtaining the research dimensions of the work stress of train driver, i.e. work itself, the conflicts between work and the family, interpersonal relationship, career development and organizational factors;(2) presenting the notion of safety support and obtain the research dimensions of safety support, i.e. safety-help, identity value and safety concern;(3) obtaining the measurement tools of the work stress, job burnout and safety support of train driver; and (4) verifying the model based on the main line (relationship of the work stress, job burnout and safety performance) and moderating variable (safety support) and checking the corresponding research hypothesis, as well as confirming the mediating effect of job burnout of the train driver on the work stress and safety performance and on the safety support of train driver.The main innovation points of the study are as follows:(1) Put forward the notions of safety support belonged to security category from the point of safety management, and discuss the relationship between the work stress of train driver and safety performance as well as expand the research field of work stress and safety performance.(2) Build and verify the model on the relationship between the work stress (independent variable) of train driver and safety performance (dependent variable) using job burnout as intervening variable and safety support as moderating variable, as well as using structural equation model to verify the mediating effect of job burnout, regulating effect of safety support and the rationality of the theoretical model built through research.(3) By comparing the regulating effect on the safety support of train driver in groups, verify the regulating effect of safety support of train driver on the relationship between work stress and safety performance and obtain the conclusion that the work stress of train driver has a different impact on the safety performance when the safety support is different.
