基于结点重要度理论的运输枢纽布局方法研究

A Study on Highway Hinges Planning Based on Node Importance Analysis Theory

在公路运输枢纽总体规划中,枢纽的选址是重要的一环,也是决定区域公路运输系统的重要因素。结点重要度分析是定量描述区域内各结点间的相对重要程度,从而为规划布局提供依据。将结点重要度理论引入公路运输枢纽布局,根据提出的相关指标应用结点重要度分析对枢纽布局备选点逐步筛选,最终确定最佳站址,从而指导运输枢纽的布局。所阐述的方法在部分公路运输枢纽总体规划中收到了良好的效果。

In the collectivity planning of highway hinges,to confirm the location of highway hinges is not only very important,but also the important condition to determine efficiency of highway transportation system in the area.The node importance analysis is employed for the quantitative description of the comparative importance of the nodes in the area,which serves as support for the planning of highway hinges.The theory of node importance is used in the distribution of highway hinges,and based on correlative condition to filtrate the initial node,to confirm optimum location,so as to conductor distribution.The mentioned theory has obtained better effect in the planning of some highway hinges.
