各运输方式的竞争性与协作性的识别研究

在连接两城市的多种运输方式间存着竞争、协作的关系，本文是通过设立两个虚拟转运地，构建交通运输网络图的方法，把运输方式间运量的转移问题转化为运输通道间运量的转移问题进行研究，综合分析当某种运输方式的运费或运行速度（即运行时间）发生变化时，各种运输方式承担客运量的变化情况，从而推理出各运输方式间的竞争性与协作性的相应结论，并给予证明和实例验证。

Study on the Distinguishing of the Rivalrousness and Cooperation Among Different Transportation Modes

Rivalrousness and cooperation relationships exist in the different transportation modes connecting two cities. The author studies these relationships by transferring the quantity diversion problem of different transportation modes to the quantity diversion problem of transportation corridors by establishing two virtual transferring sites and building transportation network map. Some conclusions about the rivalrousness and cooperation are deduced by synthetically analyzing the changing situation of passenger flows that different kinds of modes bear when the fare and operation are changed. Numerical proof and examples are also provided to demonstrate the validity of the conclusions.
