摘　　要：遵循复杂网络和空间句法的基本原则,引入计算机网络路由路径选择评价指标中跳数的思想,提出一种城市轨道交通网络拓扑特性建模与分析方法。该方法综合网络复杂度、可达性和几何特征,构建基于跳数的城市轨道交通网络拓扑评价的指标体系及计算模型;并以世界典型六大城市轨道交通网络为例,分析其网络数据的特征,提出数据处理流程,分析平均度、最短路径、特征路径长度,以及网络的邻近性、聚类系数、相对便捷性等指标,提取轨道交通网络拓扑性能评价的重要特征参数。分析结果可为轨道交通网络优化配置、运营调度及行车管理提供重要的决策支持。Following the principle of complex networks ano space syntax, the concept of hop in computer network routing path selection is introduced, a modeling and analysis of network topological characteristics for urban rail transit is proposed. This method combines the complexity, accessibility and geometrical features of rail transit network, establishes an evaluation index system and computer model based on hop count. Then, by focusing on the typical rail transit networks in 6 metropolises of the world, their rail transit network topological structures and index like shortest path, network propinquity, clustering coefficient and so on are analyzed,from which the important parameters of network topological characteristics assessment are extracted. The analytic result could support the policy making in network optimization,operation scheduling and traffic management.
