摘要
双层乃至多层网络的结构与功能研究是近年来复杂网络研究的一个重要方向。该文根据2016年中国列车时刻运行表,提取全国453个高速车站和2 293个普通车站作为研究对象,构建了高铁-普铁交通双层复杂网络,接着对单层高铁网络、单层普铁网络及高铁-普铁双层网络的拓扑静态指标进行分析。最后利用网络的最大连通子图这一指标对这3种铁路网络模型进行可靠性分析,研究发现交通多层复杂网络的可靠性在高速铁路网络和普通铁路网络之间。此研究为双层网络的实证研究提供了新证据,而且有利于交通部门管理和规划交通网络。
The structure and function of multi-layer networks is an important direction of complex network research in recent years. According to the 2016 Chinese train timetable, this paper extracts 453 high speed stations and 2293 lower speed stations as the research object. Based on complex network theory, multi-layer network of high speed railway and ordinary railway is built and the topological properties of higher-speed railway network,lower-speed railway network and multi-layer railway network are analyzed. In the end, using the size of largest component we research the reliability of the three networks, the results imply that the robustness of the multi-layer network is between higher-speed railway network and lower-speed railway network. These results provide new references for the empirical study of multi-layer network and optimizing the traffic network.
