城市公交超网络演化模型构建及分析

Construction and Analysis of the Evolution Model of Urban Bus Hypernetwork

为了分析城市公共交通系统演化特征并为交通规划管理提出建议,构建以公交线路为节点、公交站点为超边的城市公共交通超网络,根据现实公交系统演化特征构建公交超网络演化模型。演化模型遵循超边增长和超边超度优先连接机制,就公交超网络演化中超边超度的分布以及演化模型参数对超度分布的影响进行分析。公交超网络演化理论模型服从漂移幂律分布,超边增长数量以及旧超边连接机制都对超度分布有影响。公交超网络演化模型有助于改善公交规划与管理。

For analyzing the evolution characteristics of urban public transport system and puting forward suggestions for traffic plan?ning and management,the urban public transport hypernetwork with bus routes as nodes and bus stations as hyperedges was construct?ed,and the evolution model of the bus hypernetwork was constructed according to the evolution characteristics of the real bus system.The evolution model follows the mechanism of hyperedge growth and hyperedge preferential attachment,then we analyzed the hyperde?gree distribution of the hyperedge of the evolution of bus hypernetwork and the influence of evolution model parameters on the hyperde?gree distribution.The theoretical model of bus hypernetwork evolution model obeys the shift power law distribution,and the number of hyperedge growth and the connection mechanism of the old hyperedge all have an influence on the hyperdegree distribution.It is help?ful to improve bus system planning and management by analyzing the evolution model of bus hypernetwork.
