城市道路路口放行规律与通行能力的关系研究

路口放行规律指路口的车道数、直行、左右转布置方式、信号控制等路口管理与控制方法。选取城市中最典型的十字形交叉口为对象，结合通行能力的停车线计算法，建立了典型十字形交叉口的通行能力模型。通过改变路口车道数、信号控制、左转等待区、左转车道远引右转等路口放行规律，提高了该典型十字形交叉口的通行能力。

Study on Relationship Between City Crossing's Traffic Order Regularity and Crossing-capacity

The traffic order regularity means the method of crossing management and control such as the lines' number, the arrangement of non-turning lane, left-turning lane and right-turning lane, the signal control, etc. Taking a typical intersection as an example, the crossing-capacity model of this typical intersection is established by using the stopping line method. To improve the typical intersection's crossing-capacity, many changes in traffic order regularity such as the lines' number, the signal control, the arrangement of left-turning waiting area, the shift of left-turning line, etc,have been brought forward in the paper. And the relationship between the crossing' s traffic order regularity and crossing-capacity is cleared.
