摘要： 基于对左转专用车道停车线的研究，分析了停车线的位置与相位绿灯间隔时间和车道饱和流量这两个交叉口通行能力关键影响因素的关系在保障交又口车辆通行安全的前提下，以交叉口通行能力最大为目标，建立以左转车道停车线位置与直行车道停车线位置之间距离为基本参数的数学模型，并提出了相应的解法，最后，通过具体的交又口实例分析，求解出了左转停车线的最佳位置，证明该模型具有很好的实用性.

Abstract: Based on the study of the left-turn lane stop line, this paper discusses the relationship between the position of stop line and both the change interval and the saturation volume, which are the two critical influence factors of an intersection capacity. In the precondition of gurantecing the safety when vehicles cross the intersection, a model with the parameter of the distance between the left-turnl anes top linea ndt het hroughl anes top linei sc o. ns tru ct ed i n o rd er t oa chievet hem aximum of capacity, and the relative solution is offered. Last, through taking an actual intersection for instance, the thesis seeks the best position of the stop line, which proves that the model has good practicality.
