摘要
深入理解驾驶行为的本质特征是道路设计、交通工程、智能车辆等领域的研究基础,驾驶行为也是相关工程和产品设计的基本控制条件——道路线形和交通设施为是以中等驾驶人(中位)或者85th百分位驾驶人的行为作为设计控制依据,但统计意义上的"中等驾驶人"或者85th百分位驾驶人在真实世界中是否真实存在,目前尚未得到实证。在重庆市选择了行驶环境复杂的3条路段作为实验地点,开展了超过70位驾驶人的实车驾驶试验,用车载仪器采集了自然驾驶状态下的车辆运行数据,并用量表获取了被试者的气质类型,然后以行驶速度为中间介质、以相似性为准则,分析了中位以及85th百分位驾驶行为的存在性。研究结果证明了真实世界中确实存在"中等驾驶人",他/她的速度行为特征在包含多个复杂场景的整个路段范围内与中位值速度高度一致;"中等驾驶人"的用户画像为:40岁左右,驾龄10年左右,气质类型多为抑郁质,男性和女性都有。此外,研究结果还证实了"85th百分位驾驶行为"在真实交通世界中的存在性。
Deeply understanding of driving behaviors is the basis of road design,traffic engineering,and intelligent vehicles.Driving behaviors are also the basic principles for design control of related projects and products.Taking road geometry and traffic facilities design as case studies,the behaviors of the medium driver or 85 thpercentile driver as the design control basis,but whether the"medium driver"or 85 thpercentile driver in the statistical sense really exists in the real world,at present,it has not been proved.In this context,three road segments with relatively complex driving environment in Chongqing,China are selected as experimental sites.A field driving test for more than 70 drivers are carries out,vehicle operation data under the natural driving state was collected by on-board instrument,and temperament type of the subjects was obtained through self-reported questionnaire,then The existence of median and85 thpercentile driving behavior are analyzed with the driving speed as the intermediate medium,and the similarity as the criterion.The results prove that there is indeed a"medium driver"in actual world,and his/her behavior characteristics are highly consistent with the median value in the whole road section;the user portrait of"middle driver"is about40 years old,driving age is about10 years,and most of the temperament types are depressive,both male and female.In addition,the results also confirmed the existence of"85 thpercentile driving behavior"in actual world.
