摘要
分析了区域公路网的典型布局形式,回顾了现有的公路网连通度评价指标,指出其存在的局限性。在此基础上提出了路网加权模糊连通度的定义和计算方法,有效体现了区域公路网布局规划方案评价中存在的节点重要度的差异性和线路连通度的模糊性。最后用一个简单算例进行了验证。
After analyzing the representative layout shape of regional road network, the existing indexes for evaluation of highway network connectivity are reviewed, and the deficiency of its application in the connectivity of layout structure for regional freeway network is identified. Based on this, discussion is made on the definition and computation method of network power fuzzy connectivity. Then, the difference in point importance degree and fuzzy of line connectivity is effectively embodied. At the end, a simple calculation example is presented.
