Abstract

Long monotonous driving tasks can induce driver fatigue, significantly reducing vigilance and threatening the safety of high-speed train operations. Despite the importance of addressing this issue, effective interventions to mitigate driver fatigue in the context of high-speed railway (HSR) systems remain a challenge. This study aims to examine the effects of three tactile intervention strategies [transcutaneous electrical acupoint stimulation (TEAS), thermal stimulation (TS), and vibration stimulation (VS)] on alleviating driver fatigue. A high-speed train simulator was used to conduct experiments with subjects. Each participant was required to complete four driving tasks: one without any intervention and three with each of the aforementioned tactile interventions when experiencing fatigue. Physiological metrics such as reaction time (RT), electrocardiogram (ECG), and electroencephalogram (EEG) were collected to assess driver vigilance. The results revealed that thermal and VSs effectively reduced RTs (TS =1.11 s, VS =1.09 s, no-intervention =1.12 s) and slowed down the fatigue process. Drivers exhibited higher vigilance levels during these interventions, as reflected in improved ECG and EEG features. For example, the high-frequency energy of the EEG signal increases during the stimulation compared to before the stimulation. However, TEAS did not show significant effects on fatigue reduction. This study contributes to the literature by providing evidences to support that appropriate tactile interventions, particularly thermal and VSs, can effectively mitigate driver fatigue and improve vigilance levels. These findings offer practical insights for enhancing the safety of HSR operations by minimizing risks associated with driver fatigue.
触觉干预传感器在高速铁路驾驶员疲劳缓解中的有效性
长时间单调的驾驶任务会引起驾驶员疲劳,大大降低警惕性,威胁高速列车的运行安全。尽管解决这一问题很重要,但在高速铁路(HSR)系统的背景下,有效的干预措施仍然是一个挑战。本研究旨在探讨三种触觉干预策略[经皮穴位电刺激(TEAS)、热刺激(TS)和振动刺激(VS)]对减轻驾驶员疲劳的影响。利用高速列车模拟器对被试进行实验。每位参与者被要求完成四项驾驶任务:一项是在没有任何干预的情况下完成的,另外三项是在经历疲劳时进行上述触觉干预的。收集反应时间(RT)、心电图(ECG)和脑电图(EEG)等生理指标来评估驾驶员的警觉性。结果表明,热和VSs有效降低了RTs (TS =1.11 s, VS =1.09 s,无干预=1.12 s),减缓了疲劳过程。在这些干预期间,驾驶员表现出更高的警惕性水平,这反映在心电图和脑电图特征的改善上。例如,与刺激前相比,刺激过程中脑电图信号的高频能量增加。然而,tea并没有显示出明显的疲劳减少效果。本研究通过提供证据来支持适当的触觉干预,特别是热和VSs,可以有效减轻驾驶员疲劳和提高警觉性水平。这些发现为通过最小化驾驶员疲劳相关风险来提高高铁运营的安全性提供了实际见解。
