The Effect of EMU Driver Operating Time on Professional Psychological Quality

Purpose: EMU driver operation time is an important part of the locomotive crew system. To ensure the safe, efficient and accurate operation of the EMU (Electric Multiple Unit), drivers not only need to have good physical and mental health but also must be able to work under the conditions of a scientific, reasonable and humanized organization. Design/methodology/approach: To effectively analyze the actual job of an EMU driver and to avoid impacting the normal work of the drivers, we selected some of the items from the professional mentality test project, which we had found had resulted in short test times and high test reliability and validity. Findings: With a single-driver continuous value multiplied by a time of less than two hours, there were no significant differ ences; multiplied by more than 4 hours, there was a significant difference in psychological quality; specifically, the multiplied career mental quality level decreased significantly. The EMU single continuous value multiplied by driving time driver should not be more than four hours to receive the full benefit. Originality/value: Based on the different operating times, this study compared the organization of different jobs in different situations. The negative impact of psychological load on EMU driver labor intensity varied.
