摘要
为深入分析城市多模式交通网络的复杂特性,促进多模式交通的协同发展。采用原始映射法构建了包括小汽车网络、地面公交网络和轨道交通网络三者叠加而成的城市多模式交通网络模型。结合城市交通网络的实际运行情况,综合考虑客流量和运行时间的影响因素,对传统加权方式进行改进,方便建立更加准确、贴近现实的城市多模式加权交通网络模型。利用复杂网络的分析方法,应用Pajek和Ucinet这2种网络分析软件,对哈尔滨市多模式加权交通网络及3个单一模式子网络的复杂网络特性进行实证对比分析。提出城市多模式交通网络鲁棒性分析指标,对比研究交通网络受到攻击时的稳定性。结果表明,相比单一模式的子网络,叠加后的城市多模式交通网络聚类系数增加,节点间紧密度有所增强,具有典型的小世界特性,表现出对随机攻击的鲁棒性和对蓄意攻击的脆弱性。
In order to deeply analyze complex characteristics of urban multi-mode traffic network, promote coordinated development of multi-mode traffic. An original mapping method is use to develop a model of urban multi-mode traffic network, which consists of three parts: car network, ground bus network, and rail transit network. Combined with actual operation of urban traffic network, influencing factors of passenger flow and running time are comprehensively considered. A traditional weighting method is improved to develop a more accurate and realistic model of a weighted complex network for urban multi-mode traffic. Analysis methods of complex network are used. Software as Pajek and Ucinet is applied to compare complex characteristics of multi-mode traffic networks with three single-mode sub-networks. A robustness analysis index of urban multi-mode traffic network is proposed to comparatively study stability of the traffic network under attack. Analysis results show that, compared with three single-mode sub-networks, clustering coefficient of urban multi-mode traffic network increases, and its tightness between nodes is enhanced. The complex network for urban multi-mode traffic has typical small world property. It is robust to random attacks and vulnerable to deliberate attacks.
