平面十字交叉口停车线设计方法研究

城市道路交叉口停车线设计是影响交叉口通行秩序的重要因素之一。本文通过对平面十字交叉口的观测及分析,总结现状交叉口停车线设计的基本模式及问题,提出基于通行条件约束的交叉口停车线设计的实现目标及约束条件。将交叉口停车线设计理论化,给出平面十字交叉口停车线设计的基本模型。最后分析影响停车线设计的因素,并总结规律。在应用方面选择厦门市一个典型十字交叉口进行设计,以检验停车线设计模型的可行性。

The Analysis of Stop Line Arrangement for At-grade Intersection

The position of stop line has great effect on the traffic operation in intersection. For the geometry design of intersection, there are no available analytical models or procedures that can be used to position the stop line. In this paper, the existing considerations for stop line design in at-grade intersection are discussed and the variables that impact the arrangement of the stop line are figured out. After analyzing the targets and the restrictions of the stop line arrangement, the models for determining and optimizing the position of stop line are established and the relationship between these variables discussed. A practical application in an intersection in Xiamen is proposed to verification the procedures and models.
