Although there is evidence that suburban bus drivers experience drowsy driving, most previous studies are quantitative, which means that drivers experiencing drowsiness have not had the opportunity to explain their direct views and thoughts. OBJECTIVES: This qualitative exploratory study subjectively investigates the contextual factors influencing fatigue among suburban bus drivers. METHODS: Collecting data was conducted through 14 in-depth interviews with suburban bus drivers working in Tehran province\u2019s transportation system, Iran. The interview recording was transcribed by the research team and entered into the qualitative data analysis software. Two independent coders with qualitative content analysis and thematic analysis approach analyzed transcripts. RESULTS: Four themes emerged, including human factors (with categories of individual characteristic and lifestyle), vehicle factors (with categories of design and performance), job factors (with categories of task requirement, quantity and quality of sleep, and circadian rhythm,) and environmental factors (with categories of the physical and economic environment). We found a more significant number of codes and categories and thus more contextual factors associated with job factors. The participants emphasized the importance of sleep deprivation, long driving hours, and even time of the day as factors influencing fatigue. CONCLUSIONS: The study results can provide beneficial information for both ergonomists and car manufacturers in developing more accurate fatigue detection models and effective educational and technical interventions to maintain road user\u2019s health and reduce road accidents and mortality rates due to drowsiness.<\/jats:p>","DOI":"10.3233\/wor-210755","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T12:24:09Z","timestamp":1655468649000},"page":"1481-1491","source":"Crossref","is-referenced-by-count":4,"title":["Drivers\u2019 subjective perceptions of the contextual factors influencing fatigue: A qualitative study of suburban bus drivers in Iran"],"prefix":"10.1177","volume":"72","author":[{"given":"Farin","family":"Khanehshenas","sequence":"first","affiliation":[{"name":"Department of Occupational Health, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adel","family":"Mazloumi","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pourya Ahmadi","family":"Jalaldehi","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahdieh","family":"Kaveh","sequence":"additional","affiliation":[{"name":"Department of Occupational Health, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","reference":[{"issue":"1","key":"10.3233\/WOR-210755_ref1","first-page":"1","article-title":"The social determinants of risky driving on the intercity roads of Tehran province, Iran: a case-cohort study","volume":"6","author":"Moradi","year":"2017","journal-title":"Arch Trauma Res"},{"issue":"11","key":"10.3233\/WOR-210755_ref2","doi-asserted-by":"crossref","first-page":"442","DOI":"10.1371\/journal.pmed.0030442","article-title":"Projections of global mortality and burden of disease from 2002 to 2030","volume":"3","author":"Mathers","year":"2006","journal-title":"PLoS Med"},{"issue":"1","key":"10.3233\/WOR-210755_ref3","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1038\/srep37300","article-title":"The association between meteorological factors and road traffic injuries: a case analysis from Shantou city, China","volume":"6","author":"Gao","year":"2016","journal-title":"Sci Rep"},{"issue":"13","key":"10.3233\/WOR-210755_ref4","doi-asserted-by":"crossref","first-page":"6752","DOI":"10.3390\/ijerph18136752","article-title":"Modelling the Relationship between the Nature of Work Factors and Driving Performance Mediating by Role of Fatigue","volume":"18","author":"Al-Mekhlafi","year":"2021","journal-title":"Int J Enviro.
