摘要:
为了明确山区公路曲线路段上的汽车轨迹形态和驾驶风格,使用小客车在山区复杂线形公路上开展了实车驾驶实验.记录了自然驾驶状态下男性驾驶人的行驶轨迹,分析了行驶轨迹相对于行车道中线的横向偏移特性,运用聚类方法识别了曲线路段的轨迹行为模式.结果发现:根据轨迹横向偏移率的聚类结果,山区公路曲线路段有6种轨迹模式,具有明显的多样性特征;切弯是曲线路段占主导的过弯方式,按照切弯点位置以及前后的轨迹形态,切弯又可进一步细分为多种类型;行驶轨迹的横向偏移导致了车道偏离,其中非预期偏离由于存在较高的事故风险,应进行防范和控制;平曲线半径越小,切弯效应越大,事故风险可控,驾驶人越倾向于采用切弯方式来通过弯道,曲线路段是否发生切弯行为的临界半径值为200 m.
Abstract:
To specify the track patterns and driving styles on curved section of mountain roads, the field driving test using passenger cars was conduced, natural driving data of vehicle track of male drivers on mountain roads with complex alignment were recored, the lateral deviation characteristics of track were analyzed, and the track patterns on curved sections by the clustering method were recognized. The results show that six track patterns are identified for the curved sections of mountain roads according to the clustering results of lateral deviation rate curves, i.e., pattern diversity existing in track behavior. Curve-cutting is a dominant bend negotiating mode. According to the location of the cutting point and the track shape nearby cutting point, more types can be identified for curve-cutting behavior. The lateral deviation in track leads to lane deviation. non-expected deviation should be prevented and controlled due to its high accident risk. A sharper curve can produce a greater benefit from curve-cutting behavior and a more controllable accident risk, so curve-cutting would be more preferred by drivers; otherwise, the cutting utility weakens and the risk of accidents increases. The threshold of curve radius whether cutting occurring is 200 m.
