摘　　要：为预防由驾驶疲劳引起的交通事故,有必要研究在道路、交通和环境的综合影响下驾驶疲劳的生成机理。基于生理、心理学中的经典理论,借鉴国内外相关的研究成果,采用理论推理的方法对驾驶疲劳生成过程中驾驶员唤醒水平的变化规律及其影响因素进行分析。在此基础上建立了驾驶疲劳的生成模型,并将模型应用于工程实际。通过驾驶员唤醒水平的变化,指出驾驶疲劳的生成时刻,及其对驾驶时间的规定和道路、景观设计的影响。该模型以唤醒水平为核心,描述驾驶疲劳生成过程中驾驶员唤醒水平的变化规律,强调道路交通环境对驾驶员唤醒水平的影响。In order to improve traffic safety, the formation mechanism of driving fatigue is researched, which is influenced by road, traffic and environment. Based on related physiological theories, psychological theories and previous studies, the theoretical reasoning method is used to analyze the change pattern of driver arousal level and its factors during the forming process of driving fatigue. Then a formation model is established and applied into engineering practice. According to the changing rule of driver arousal level, the time of occurrence of driving fatigue is determined, and then suggestions about driving time regulations, road design and landscape design are proposed. This model, with arousal level at its core, well describes the change pattern of driver arousal level during the formation of driving fatigue and emphasizes the influence of road traffic environment on driver arousal level.
