城市公共交通网络RLP建模及复杂性分析

摘要

The complex network theory is applied to establish three proper public transport network to‐pologies including L -Space ,P‐Space ,R‐Space by taking the present public transport network of Bao‐ji as an example .Besides , the topological structure properties are studied by calculating statistical properties such as degree distribution ,characteristic path ,clustering coefficient and betweenness cen‐trality ,and the three established network models are compared .At last ,under the circumstances of both calculated attack and stochastic attack ,the network reliability is evaluated by two indicators that are the network efficiency and relative connectivity .The results show that the public transport net‐work appears to share the small‐world and scale‐free properties .In addition ,under a calculated at‐tack ,the route network is found to exhibit vulnerability .%基于复杂网络理论，以宝鸡市现状公交路网为例，首先构造3种公共交通网络拓扑结构模型，即R‐Space网络模型，L‐Space网络模型，P‐Space网络模型。从度、特征路径、聚类系数、介数等参量出发分析其拓扑静态结构特性，并对3种网络模型进行了比较。针对蓄意攻击和随机攻击，采用网络效率和相对连通度两个指标评价网络可靠性。结果表明，3种网络模型都满足小世界特性，站点网络还具有无标度特性，城市公共交通网络在蓄意攻击下表现出脆弱性。
