摘　　要：为解决驾驶员在隧道中间段因驾驶疲劳带来的行车安全问题,对隧道驾驶疲劳唤醒段设置长度进行研究。首先,建立疲劳唤醒段的刺激量与其产生疲劳唤醒后对驾驶员的唤醒程度以及唤醒维持时间的相互关系;然后,进行蓝、紫、青3种色彩,3种亮度及5种刺激持续时间共45种不同刺激量组合下疲劳唤醒段的静态唤醒试验,研究隧道疲劳唤醒段不同刺激量对被试驾驶员唤醒程度的影响规律,建立刺激量与唤醒程度的相关关系模型,得到疲劳唤醒段刺激量应不低于8.84 cd·s/m^(2);最后,分析不同刺激量的疲劳唤醒段对驾驶员唤醒的维持时间,建立不同运行速度条件下疲劳唤醒段刺激量与唤醒维持时间的相关关系模型,根据不同运行速度下隧道疲劳唤醒段侧壁可设置的最高亮度,得到不同运行速度下隧道疲劳唤醒段应设置的长度。当设计速度为60、80、100 km/h时,第x(x∈[1,N-1])处疲劳唤醒段的设置长度分别为160、200、220 m,第N处疲劳唤醒段的设置长度应保证剩余路段驾驶员的正常驾驶,且不低于65、80、90 m。The rational setting length of the driving fatigue arousal section in a tunnel is studied to reduce the driving safety risk caused by driver fatigue in a tunnel′s middle section.First,consider the interaction between the amount of stimulation in the fatigue arousal section,the driver′s fatigue arousal degree,and the driver′s fatigue arousal maintenance time after fatigue arousal has been established.Second,static arousal tests are performed using 45 test scenarios that include three colors(blue,purple,and cyan),three brightnesses,and five stimulation durations.The law of arousal degree of drivers after roused in fatigue arousal sections with different stimulus quantities is investigated,and a correlation model between stimulus quantity and arousal degree is established,yielding a minimum stimulation quantity setting in the fatigue arousal section of no less than 8.84 cd·s/m^(2).Third,the arousal maintenance time of drivers after stimulation in the arousal section with different stimulus quantities is investigated,and a correlation model between stimulation quantity and arousal maintenance time under various operating speeds is established.Based on the maximum brightness of the tunnel fatigue arousal section that can be set on the sidewall at different speeds,the reasonable length of the fatigue arousal section in the tunnel at different speeds is obtained.Finally,when the design speed is 60,80,and 100 km/h,the lengths of the driving fatigue arousal section at x(x∈[1,N-1])are 160 m,200 m,and 220 m,respectively;the lengths of the last driving fatigue arousal section should meet the normal driving of the remaining sections and should not be less than 65 m,80 m,and 90 m.
