Abstract: (23 Views)
Background: The subway environment is a crucial and widely utilized component of modern transportation. Various factors significantly affect the comfort and performance of subway employees, drivers, and passengers. Therefore, this study aims to investigate the relationship between sound, vibration, and lighting conditions and their impact on fatigue. The research focuses on chronic and work-related stress among two groups: metro conductors and ticket vendors.
Methods: This study employed a descriptive-analytical cross-sectional design. The statistical population consisted of 30 metro conductors and 30 urban train ticket sales staff in Shiraz. After enrollment, participants completed the ERIQ questionnaire. Sound quality was evaluated using a sound level meter, while lighting levels were measured with a lux meter. Additionally, vibration was assessed according to the ISO 2631-1 standard using a calibrated vibration meter. Data were analyzed using descriptive and inferential statistical techniques in SPSS.
Findings: The results of the present study showed that the sound pressure levels in both investigated sections were below the standard limit, while the vibration level in the subway cab exceeded the standard exposure limit. A significant difference was observed in chronic fatigue and occupational stress between conductors exposed to noise, vibration, and lighting and employees without such exposure, indicating a greater impact of these factors on subway conductors. In examining occupational stress, significant differences were found between the two subscales of effort and over-commitment. The most common stress level experienced by both groups was moderate, and no participants in either group reported a high level of job-related stress.
Conclusion: The levels of chronic fatigue and occupational stress among subway conductors are higher because they are directly exposed to physical stressors. Therefore, further research is needed in this area, along with the implementation of appropriate measures to maintain the health and improve the efficiency of subway conductors.
