In recent years there has been rapid development of urban rail transit in China. The train driver, as the direct controller of the train, plays an important role in subway operation, and their driving performance directly determines whether the train is safe or not. To explore the relationship between fatigue and unsafe behavior, a simulated driving experiment was designed to record the train driver’s behavior under fatigue and normal state. The changes of operation accuracy and timeliness are used in combination to reflect the train driver’s unsafe behavior. The results show that when the train driver is in a state of fatigue, their operation accuracy is 126% lower than in the normal state. In the operation timeliness index, the time required for the train driver to react and complete the action is 28.13% and 17.7% longer than that in the normal state. It is concluded that fatigued driving can easily lead to unsafe behavior which then leads to potential safety accidents.

近年来，我国城市轨道交通发展迅猛。列车司机作为列车的直接控制者，在地铁运营中扮演着重要的角色，其驾驶表现直接决定列车的安全与否。为探究疲劳与不安全行为之间的关系，设计了模拟驾驶实验，记录了列车驾驶员在疲劳和正常状态下的行为。结合运行准确性和时效性的变化来反映列车司机的不安全行为。结果表明，当列车司机处于疲劳状态时，其操作精度比正常状态下降低126%。在运行时效指标中，列车司机反应完成动作所需时间分别为28.13%和17。比正常状态长7%。结论是疲劳驾驶容易导致不安全行为，进而引发安全事故。
