城市道路网的度相关性研究

Degree Correlation of Urban Street Networks

  • 摘要: 目的 研究了基于stroke相交关系表示的道路网对偶图中的节点度的相关性。运用同配性系数,对美国40个城市道路网进行了实验,发现这些道路网既是同配的,又有异配的。同配性道路网具有易流通性和抗破坏性,这一点在城市规划领域具有潜在应用。本研究与前人的研究结论不同,对可能的原因进行了讨论。

     

    Abstract: Objective In this paper,we use the assortative coefficient to study the degree correlation of urbanstreet networks as represented by stroke intersections.It is found that some street networks demon-strate an assortative mixing pattern and others demonstrate disassortative mining pattern.The assor-tative networks would percolate easily and are resilient to breaks.This demonstrates potential forgeneral applicability to urban planning.Our conclusions are opposite to previous work and possiblereasons are discussed.
