“四阶段法”中运量分配的路网断面剖切技术研究

针对"四阶段法"的运量分配过程中存在对路网动态变化的适应性反应迟钝、相关径路双向交流产生的大量回流量重复计算、通道交流量缺乏总量控制调节关键环节等问题,提出采用路网断面动态剖切技术,给出具体操作步骤和基本算法,并与传统运量分配方法进行优劣分析。通过宝中线运量预测的实例计算分析,说明断面剖切技术的实际应用。

Research on Railway Network Section Cutting Technology of Traffic Volume Distribution in “Four Phases Method”

To address the issue of slow response to the adaptability of the dynamic change in the railway network,massive back circuit repetitive computation caused by related route two-way communication,and key link of lack of total control adjustment for passage communication volume which existing in the process of traffic volume distribution based on "four phases method",it is proposed to adopt railway network section dynamic cutting technology,provide specific operation procedures and basic calculation,and conduct analysis of advantages and disadvantages with traditional loading distribution method.Through practical analysis of traffic volume forecast of Baoji-Zhongwei line,the practical application of section cutting technology is specified.
