摘要
详细介绍目前国内外常用的4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、停车线法、冲突点法),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,并将结果与实测通行能力进行比较,探讨最适合我国交通条件和混合交通流特性的通行能力计算方法。初步评价各种方法的优缺点及适用范围,旨在使国内有关信号交叉口通行能力的计算有一个统一的标准。
This paper gives a detail introduction to 4 popular signal junction traffic capacity calculation methods （saturation volume rate model, urban road design criterion, stop line method, conflict point method）, a typical cross signal junction is taken as example to calculate the traffic capacity of this junction, and the calculated results are compared with actual measured traffic capacity, so to explore the traffic capacity calculation method that is most suitable for traffic conditions in China and the mixed traffic features. It pays a basic evaluation to advantages, disadvantages and application range of all calculation methods, so to set up a unified standard for signal junction traffic capacity in China.
