信号交叉口通行能力计算方法比较研究
首发时间:2009-03-30
摘要:详细介绍目前国内外常用的2种计算信号交叉口通行能力的方法(饱和流率模型、城市道路设计规范推荐的方法),以一个典型十字型信号交叉口为例,计算该交叉口的通行能力,利用各自计算所得的饱和度与现场观测的服务水平比较,评价两种方法的优缺点及适用范围,旨在完善国内有关信号交叉口通行能力的计算方法。

Comparison Discussion of Calculation Methods for Traffic Capacity at Signal Intersection
Abstract:This paper gives a detail introduction to 2 popular signal intersection traffic capacity calculation methods (saturation volume rate model, urban road design criterion), a typical cross signal intersection is taken as example to calculate the traffic capacity of this intersection, and the calculated results are compared with actual performance. It pays a basic evaluation to advantages, disadvantages and application range of all calculation methods, so to set up a unified standard for signal intersection traffic capacity in China.
Keywords: signal intersection traffic capacity saturation volume rate model urban road design criterion
