摘　　要：影响驾驶疲劳的因素很多。作为驾驶疲劳主要影响因素之一的道路交通环境,是以动态形式展示在驾驶员视野中并产生作用的,有必要针对道路交通环境的动态特性进行专门研究。首先理论分析动态道路交通环境相互制约和影响的持续变化性和自主可控性。据此设计了基于3个场景的2组现场实车试验。然后以驾驶员的心率作为测量指标,研究动态道路交通环境对驾驶疲劳的影响。通过对比分析驾驶员的心率随道路交通环境场景的变化程度和行车速度大小的变化规律,发现道路交通环境变化性的大小会对驾驶疲劳的形成和发展产生影响。因此,合理设计道路交通环境的变化性能够减缓驾驶疲劳,提高道路的安全水平。Many factors can affect driving fatigue. As one of the main factors, road traffic environment is dynamic in drivers＇ visual field and can influence drivers in that way, therefore, researches about road traffic environment should be focused on its dynamic characters specifically. The continuous change and autonomous controllability which interact and constrain each other in dynamic road traffic environment were theoretically analysed at first. Based on this, two experiments which include 3 scenes were designed and performed. Then, taken driver＇s heart rate as the indicator, the impact of dynamic road traffic environment on driving fatigue was studied. By comparing drivers＇ heart rates in different road traffic environments and at different driving speeds, it is found that the formation and development of driving fatigue can be affected by changes of road traffic environment. Therefore, designing changes of road traffic environment rationally will delay or alleviate driving fatigue and improve traffic safety.
