Abstract

The impact of tunnels on driver performance is significant, yet it remains understudied in the context of high-speed rail. This study investigated the effects of continuous tunnel driving on high-speed rail drivers’ mental fatigue and brain functional connectivity using electroencephalography (EEG) and graph theory. Forty-two participants performed simulated driving tasks in continuous tunnel and plain scenarios. Results demonstrated that tunnel scenarios significantly elevated subjective fatigue and prolonged reaction times (p < 0.001). EEG analysis revealed increased functional connectivity in the α, θ, and β bands, particularly in frontal, parietal, and central regions. Graph theory metrics showed reduced characteristic path length and increased clustering coefficient in the θ band during tunnel driving, indicating a shift toward small-world network topology. These findings emphasize the importance of in-depth research on driver fatigue in high-speed rail tunnel operations to develop targeted intervention measures.

隧道连续驾驶对高铁司机脑反应的影响

隧道对驾驶员行为的影响是显著的，但在高速铁路的背景下仍未得到充分研究。利用脑电图和图论研究了隧道连续驾驶对高铁司机精神疲劳和脑功能连通性的影响。42名参与者在连续的隧道和平原场景中进行模拟驾驶任务。结果表明，隧道场景显著增加主观疲劳和延长反应时间(p <；0.001)。脑电图分析显示，α、θ和β波段的功能连通性增加，特别是在额叶、顶叶和中央区域。图论指标显示，隧道行驶过程中特征路径长度减小，θ波段聚类系数增大，向小世界网络拓扑结构转变。这些发现强调了深入研究高速铁路隧道运营中驾驶员疲劳对制定有针对性的干预措施的重要性。
