摘要
节点重要度是节点层次划分的依据,节点层次划分又是路网布局优化的依据,因此,节点重要度的计算是公路网规划中非常重要的一个环节。基于灰色关联分析的公路网节点重要度测算方法避免了指标选取与权重确定的主观性,对公路网规划与布局优化具有较强的理论指导意义。
Node importance is the basis of node-level classification, at the same time node -level classification is based on optimizing the layout of road network, so calculation of node importance is an important degree of the road network planning. Highway network node importance calculation method based on gray relatedness degree avoids the subjective during process of indicators selection and calculation of weight coefficient, which has the more important theoretical and practical significance on highway network planning and lay-out optimization.
