针对现有规划方法因缺乏线网形态定量确定致使线路功能层次不清的缺陷,提出一套以线网形态定量确定为依据、以覆盖最大相关性客流为目标的线网规划方法。首先在城市功能片区合理划分及客流场强分布有效计算的基础上,给出线网整体形态布局的定量分析方法,界定各条线路的经由片区及宏观走向;其次针对具体线路,在确定其有效搜索域的基础上给出区域内客流集散点的析取与匹配优选方法;然后以优选后的集散点为控制点,以完成最大直达客流为目标,实现单条线路的优化布设;最后在对OD表修正调整的基础上,实现逐条布线,优化成网。由于给出了线网宏观形态的定量确定方法,与已有方法相比明确了线路的功能定位及宏观走向,此外通过集散点的优选匹配,提高线路对客流的有效覆盖。

英文摘要：

Being lack of quantitative determination of networks morphology, the existing network planning method leads to defects of confused function levels. This paper proposes a set of network planning methods, which cover the maxmunm passenger flows according to quantitative determination of network morpology. On the basis of reasonable division of urban function regions and effevtive calculation of passengers flow field inten- sity, the macro trend and passing-region of each line are determined. The paper works out effective searching do- mains and puts forward a selection and optimized matching method of regional passenger flows distribution cen- tres. Aiming at the largest through passegers flows, the optimized distribution of a single line is realized with the distribution centres being taken as the control points. The paper regulates OD tables so that lines are loca- ted one by one and form optimized neworks. Due to the given method, network macro morphology is deter- mined quantitativly,which makes the function orientation and macro trend of lines clearer. What is more, effec- tive coverage of passengers flows is enhanced in terms of optimized matching of distribution centres.
