无信号交叉口通行能力折减系数计算法

A method for Unsignalized Intersections of Capacity Estimation

以系统的观点分析各种影响通行能力的因素 ,并将其量化 ,从而得出不同几何类型、不同交通条件下无信号交叉口的实际通行能力。交叉口的实际通行能力为基本通行能力与各项因素影响修正系数的连乘积。方法简单便利 ,适合于工程应用。

This paper presents a system method that calculates the actual capacity under the different geometric conditions and different traffic conditions by analyzing all kinds of affective factors The actual capacity equals to product of the basic capacity and a serial of adjustment factors The method is simple and accurate for traffic engineering
