城市道路复杂网络单元脆弱性实证研究

Research on unit vulnerability in urban road complex network

为分析城市道路复杂网络的拓扑性质及识别脆弱单元,以十堰市为例,选取98条线路和128个节点为样本数据,以交叉口作为节点,相邻节点之间的道路作为边,采用原始法运用复杂网络理论构建基于邻接站点的复杂网络模型,从城市道路网络拓扑结构特性和状态特性的角度阐述了网络单元综合脆弱性及其内在联系,计算其脆弱性指标。结果表明,网络拓扑结构和功能状态共同影响了城市道路复杂网络单元的脆弱性。

For analyzing topological properties and vulnerability unit of urban road complex network, we selected 98 lines and 128 nodes as data base at Shiyan city. With intersections as the nodes and adjacent roads as the links, we constructed complex network model based on adjacent nodes with the primal approach, unit comprehensive vulnerability and its internal relations from urban road network topology characteristics and state characteristics. The vulnerability indexes were calculated. The results show that urban road complex network topological properties and functional state together have the impact on unit vulnerability.
