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。 The correlation between node degree in road network dual graph based on stroke intersection relation is studied. Using the same coefficient of compatibility, experiments were carried out on 40 urban road networks in the United States, and found that these road networks are both congruent and mismatched. The same-sex road network is fluid and destructive, which has potential applications in the field of urban planning. This study is different from previous studies, and the possible causes are discussed.
