货流分布的竞争机会模型

An Intervening Opportunities Model for Cargo Trip Distribution

本文对国内外常用的交通分布模型进行了评析，指出了增长系数法和重力模型所存在的缺点和问题。并通过货流分布规律的研究，提出了货流分布的竞争机会模型。

This artical analyses the trip distribution models which are widely used in the world and points out the shortcomings and problems in those models. The differences of trip distribution between passenger flow and cargo flow are also analysed,then,a practical intervening opportunities model which is suitable for predicting cargo trip distribution is given.
