基于OD分布的运输通道识别方法

为了弥补运输通道分析方法的缺陷,本文结合运输通道＂带状分布＂、＂客货流密集＂等特征,提出了基于OD分布的运输通道定量识别方法。首先利用图论,在OD分布图上识别出所有抽象的带状路径,并结合OD矩阵筛选出其中OD量最大的一条或多条路径,然后通过区域产业轴线、城镇轴线以及交通轴线的定性验证,确定运输通道。最后,对驻马店市运输通道进行实例分析,结果表明其精确度较高,具有科学合理的实用性。

Identification of Transportation Corridor Based on OD Distribution

In order to make up the deficiencies in analytical methods of transportation corridor,a quantitative identification method for transportation corridor was proposed based on the OD distribution with ＂ zonal distribution ＂,＂ passenger and cargo flow-concentration＂ and other characteristics of transportation corridor. This method firstly used graph theory to identify all the abstract ribbon paths in the OD distribution map,and selected a largest OD path or more paths combined with the OD matrix,then,through the industrial axis,urban axis,as well as transport axis,the transportation corridor was determined. Finally,the method was used to identify the transportation corridors of Zhumadian city. The result showed that the method was reliable,scientific and rational.
