驾驶操作疲劳风险评价测试方法及趋势研究

Test Methods and Trends of Driving Fatigue Risk Assessment

驾驶操作疲劳是引起交通事故、造成驾驶员职业病的主要原因之一。由于疲劳本身的不确定性,导致驾驶操作疲劳评价测试工作一直存在较大的困难。基于现有驾驶操作疲劳评价测试方法的研究现状对未来趋势进行分析和展望。通过检索关键词,阅读整理相关文献,了解目前交通运输工具和工程车辆所使用的驾驶操作疲劳评价测试方法,分为主观判断疲劳评价测试(如问卷调查、自评量表等)和客观判断疲劳评价测试(如脑电图(EEG)、面部识别等)。研究表明,了解受试者真实的生理和精神状态,是有效避免交通事故发生和预防驾驶员职业病的重要途径。最后,得出未来的研究趋势将是努力提高生理特征测量的稳定性、面部识别的准确率、数据获取的真实性以及构建统一的驾驶操作疲劳评估模型。

Driving fatigue is one of the main causes of traffic accidents and occupational diseases.Owing to the uncertainty of fatigue itself,there are always great difficulties in the fatigue test of driving operation.On the basis of the current research status of driving fatigue evaluation and test methods,the future trend was analyzed and prospected.By searching keywords and reading and sorting relevant literature,the current driving fatigue evaluation test methods used in transportation vehicles and engineering vehicles were classified as subjective judgment fatigue evaluation test,such as questionnaire survey and self-rating scale,and objective judgment fatigue evaluation test,such as electroencephalogram(EEG)and facial recognition.The research shows that it is an important way to avoid traffic accidents and prevent drivers from occupational diseases to understand the subjects'real physical and mental state.Finally,it is concluded that the future research trend will be focused on improving the stability of physiological feature measurement,the accuracy of facial recognition,the authenticity of data acquisition,and the construction of a unified driving fatigue assessment model.
