Abstract

Sleep-related driving fatigue has been recognised as one main cause of traffic accidents. In Indonesia, experiment-based driving fatigue study is still very limited, therefore it is necessary to develop laboratory-based experiment procedure for sleep-related fatigue study. In this preliminary study, we performed a literature review to find references for the procedure and three pilot experiments to test the instruments and procedure to be used in measuring driving fatigue. Three subjects participated, both from experienced and inexperienced drivers. Our pilot experiments were performed on a driving simulator using OpenDS software with brake and lane change test reaction time measurement. We measured sleepiness by using Karolinska Sleepiness Scale (KSS) Questionnaire. The conditions of the experiment were based on illumination intensity as well as pre- and post-lunch session. We found that lane change reaction time is more potential than brake reaction time to measure driving performance as shown by the more fluctuating data. Post-lunch seems to induce drowsiness greater than illumination intensity. KSS questionnaire seems non-linear with driving performance data. We need to test further these speculations in the future studies involving a sufficient number of subjects. We also need to compare the effect of circadian rhythm and sleep deprivation on driving fatigue. The use of eye closure and physiological measurement in further study will enable us to measure driving fatigue more objectively. Considering the limitations, more preliminary experiments are required to be performed before conducting the main experiment of driving fatigue.

印度尼西亚驾驶员睡眠疲劳试验的初步调查
与睡眠有关的驾驶疲劳已被认为是交通事故的主要原因之一。在印度尼西亚,基于实验的驾驶疲劳研究仍然非常有限,因此有必要开发用于睡眠相关疲劳研究的基于实验室的实验程序。在这项初步研究中,我们进行了文献综述,以寻找该程序的参考文献,并进行了三个试点实验,以测试用于测量驾驶疲劳的仪器和程序。三名受试者参加了测试,他们分别来自经验丰富和缺乏经验的驾驶员。我们的试点实验是在驾驶模拟器上使用OpenDS软件进行的,并测量了刹车和变道测试的反应时间。我们使用卡罗林斯卡嗜睡量表(KSS)问卷来测量嗜睡程度。实验的条件是基于光照强度以及午餐前后的时间。我们发现,如波动较大的数据所示,变道反应时间比刹车反应时间更有可能衡量驾驶性能。午饭后似乎比光照强度更容易引起嗜睡。KSS调查问卷似乎与驾驶表现数据呈非线性关系。我们需要在未来涉及足够数量受试者的研究中进一步检验这些推测。我们还需要比较昼夜节律和睡眠剥夺对驾驶疲劳的影响。在进一步的研究中使用闭眼和生理测量将使我们能够更客观地测量驾驶疲劳。考虑到这些局限性,在进行驾驶疲劳的主要实验之前,需要进行更多的初步实验。
