摘要
为给运输通道中各种运输方式及其运输能力配置提供理论依据,运用数理抽象方法,从不均衡分布、互动性、多样性、经济性等角度分析运输需求的生成机理,提出均衡性、均匀波动型、两端高峰型三种典型生成规律及其应用价值。分析认为:不同的运输需求生成规律,其需求量分布存在较大差异;各种运输方式优势的比较、通道运输能力的配置必须建立在不同运输需求生成函数的基础上。
In order to provide theoretical basis for the transportation capacity allocation for different mode of transport in the corridors, this paper uses the uneven distribution, interactivity, diversity and economic factors to analyze the demand generating mechanism. Then, it discusses the three typical gener- ating mechanisms and their practical value from the abstract mathematical perspectives, which are bal- anced law, uniform-fluctuations law and the ends-peaks law. Though different transportion demand gener- ating mechanisms have bigdifferences in demand distribution, each kind of transportation mode superiori- ty comparison and the corridor transport capacity disposition must be established on the basis of different transportation demand generating function.
