A psychophysiological study on the ability for self-monitor and prediction about the influence of driving fatigue

1.对驾驶员在夜间驾驶时如何预测自身嗜睡的未来进展进行了实验。这一问题对交通运输行业的安全驾驶规划具有重要意义。驾驶模拟器的实验结果表明：1)对自身困倦的预测具有一定的可能性。2)未来半夜/清晨的嗜睡倾向于被低估。3)小睡的效果何时发生比较难预测。编制了职业驾驶员事件调查问卷。调查问卷包括司机在出发前要填写的疲劳和身体状况等问题。其他问题则询问嗜睡或疲劳是否与报道的事件有关。对卡车、出租车和公交车司机的事件报告的分析结果表明，该方法能够分析事件与睡眠之间的关系。将本项目开发的工具和方法应用于对药物嗜睡性的评估。讨论了影响职业车辆驾驶员疲劳和嗜睡的各种因素，包括工作条件和心理社会因素，并在此基础上总结了职业车辆驾驶员嗜睡的应对措施。

1. An experiment was performed concerning how vehicle drivers could predict the future progress of own sleepiness in night driving. This problem is important to planning for safe driving in the transportation industry. Results of the experiment using driving-simulator indicate that 1) The prediction of own sleepiness was possible to some extent. 2) Future sleepiness in midnight/early morning tended to be underestimated. 3) The time when the effect of the nap will occurs is relatively difficult to predict.2. A questionnaire for professional driver's incidents was developed. The questionnaire includes items to ask about fatigue and physical condition to be filled by the drivers before their departure. Other items ask whether the sleepiness or fatigue had relation to the incident reported. Results of some analysis for incident-reports from truck, taxi and bus drivers showed that such method enabled analysis of the relations between incidents and sleepiness.3. The tools and methods which were developed in the project were applied to evaluate sleepiness by the drug.4. Various factors including working conditions and psycho-social factors which influence fatigue and sleepiness of the occupation vehicle driver were discussed, and measures of the sleepiness were summarized based on these results of research.
