摘　　要：城市交通系统是一个动态、开放的复杂系统。交通堵塞和交通事故频发会对现代化城市建设和发展造成负面影响,合理安排交通线路及站点无疑具有较大的现实意义。基于复杂网络的基本理论,建立了盐城市区公交站点的网络模型,并分析其拓扑性质;根据盐城市公交网络实际数据,利用所建网络模型计算公交网络特征参数,验证了该模型的小世界性和无标度性;构建评价指标,对实际采集数据进行仿真和分析,结果表明:盐城市区公交网络具有较强的鲁棒性。The urban transport system is a dynamic,open and complex system.Frequent traffic congestion and accidents will have a negative impact on the construction and development of modern cities.Reasonably arranging traffic routes and stations undoubtedly has great practical significance.Based on the basic theory of complex networks,a network model of bus stops in Yancheng urban area is established,and its topological properties are analyzed.According to the actual data of Yancheng public transport network,the characteristic parameters of public transport network are calculated by using the established network model,which verifies the small world and scale-free nature of the model.The evaluation index is constructed,and the actual collected data are simulated and analyzed.The results show that the bus network in Yancheng urban area has strong robustness.
