公路平面交叉口右转专用车道计算方法

Calculation Method of Exclusive Right-turn Lane in Highway Intersection

在综述国内外研究现状的基础上,对公路平交口右转专用车道的设置条件,设置方法进行了研究.通过对右转车辆转弯过程的微观解析,提出了信号交叉口及无信号交叉口偏置右转专用车道长度的计算方法,并通过分析无偏置条件下的非正常变道车辆对后续右转车流的影响,提出了无偏置右转车道的长度计算方法.

Researches have been constructed on the establishing condition and methodology of exclusive right-turn lanes on the basis of summarizing the domestic and foreign researches. Through microscopic analysis of the rightturn vehicles＇ curve process, this paper has proposed the length computational method of the offset exclusive rightturn lanes at signalized and non-signalized highway intersections, Moreover, by analysizing the influence of unusual vehicles on non-offset exclusive right-turn lanes, it has presented the length computational method of non-offset exclusive right-turn lanes.
