Abstract
Fatigue and stress are critical variables that impair railway train drivers' safety performance, and individual differences may influence these effects. This study investigates how fatigue and stress affect high-speed train drivers' human error and the role of individual differences. We hypothesised that situation awareness (SA) mediates the effects of fatigue and stress on human error, and individual differences (age and work experience) moderate these effects. We surveyed 1,391 male drivers from eight Chinese railway bureaus and used PROCESS Macro for data analysis. The results revealed that fatigue and stress increased human error, directly and indirectly through SA. Age and work experience moderated the effect of fatigue and stress on SA, respectively. Older drivers had better SA under high fatigue, while more experienced drivers had better SA under high stress. These findings can inform more tailored safety management strategies to lower human error and enhance the safety of high-speed train operations.
疲劳和压力是影响铁路列车司机安全性能的关键变量，而个体差异可能会影响这些影响。本研究探讨了疲劳和压力如何影响高速列车司机的人为失误以及个体差异的作用。我们假设，情境意识（SA）是疲劳和压力对人为失误影响的中介，而个体差异（年龄和工作经验）则会缓和这些影响。我们对中国八个铁路局的 1391 名男性司机进行了调查，并使用 PROCESS Macro 进行了数据分析。结果表明，疲劳和压力会直接或间接地通过 SA 增加人为失误。年龄和工作经验分别调节了疲劳和压力对驾驶安全的影响。年龄较大的驾驶员在高疲劳度下的安全系数更高，而经验丰富的驾驶员在高压力下的安全系数更高。这些发现可以为更有针对性的安全管理策略提供参考，从而降低人为失误，提高高速列车运行的安全性。
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
