【摘要】 城市公共交通系统可用复杂网络来表示并在此基础上对其进行研究的。通过引入复杂网络分析中一些常见的重要拓扑参数例如度分布、平均路径长度、聚类系数和介数等来对城市公交系统进行分析,以西安市公交系统为例,计算并分析了这些拓扑参数,并从交通工程的角度对这些拓扑参数的具体意义进行了研究,最后从城市公交规划和环保的角度为城市公交系统的建设提出了一些建议。更多还原

【Abstract】 Urban public transportation system can be represented by complex networks and can be researched into on the basis of these models.The paper analyzed urban public transportation system by introducing some basic and important topological parameters such as degree distribution,average path length,clustering coefficient and betweeness and so on which were used in complex network analysis.Taking the public transportation system in Xi’an for example,these topological parameters were calculated and analyzed,and the concrete meanings of these topological parameters were studied from the perspective of transportation engineering.Finally,from the perspective of urban bus system planning and environmental protection,some important perspectives and proposals were given to the city public transportation.更多还原
