公共交通网络的结构和性质对城市规划、公共政策和传染病控制具有重要意义。我们贡献了一个复杂的加权网络分析的旅行路线上的新加坡铁路和公共汽车运输系统。我们研究了这两个网络的拓扑和动力学分析。我们的研究结果提供了额外的证据，动态研究增加了传统的拓扑分析所获得的信息，提供了更丰富的复杂加权网络的视图。例如，虽然最初的拓扑测量显示铁路网络几乎完全连接，但动态测量突出了经历不成比例的大流量的枢纽节点。总线网络的动态可拓性也不同于其拓扑对应物。此外，加权特征向量中心的检查突出了两个网络在工作日和周末的交通流量的显着差异，这表明了添加从许多以前的研究中缺失的时间角度的重要性。皇冠版权所有（c）2010出版的爱思唯尔B.V.保留所有权利。
The structure and properties of public transportation networks have great implications for urban planning, public policies and infectious disease control. We contribute a complex weighted network analysis of travel routes on the Singapore rail and bus transportation systems. We study the two networks using both topological and dynamical analyses. Our results provide additional evidence that a dynamical study adds to the information gained by traditional topological analysis, providing a richer view of complex weighted networks. For example, while initial topological measures showed that the rail network is almost fully connected, dynamical measures highlighted hub nodes that experience disproportionately large traffic. The dynamical assortativity of the bus networks also differed from its topological counterpart. In addition, inspection of the weighted eigenvector centralities highlighted a significant difference in traffic flows for both networks during weekdays and weekends, suggesting the importance of adding a temporal perspective missing from many previous studies.
