摘　　要：城市群铁路客运站点与网络的可达性与旅客城际出行的便捷顺畅息息相关。基于复杂网络Space-P建模方法,从城际旅客实际出行时间与出行费用出发,建立有向有权的城市群铁路客运城际网络;在城际网络基础上考虑站点间的城市公共交通换乘,标定站点间的换乘时间与换乘费用,建立耦合网络;采用平均最短旅行时间、平均最低出行费用、平均最低综合出行成本分别评估节点与网络的出行时间、出行费用、综合可达性;以成渝城市群铁路客运网络为实例进行研究。结果表明:耦合网络相较于城际网络,出行时间、出行费用、综合可达性分别提升5.45%,11.89%,8.23%,推动不同运输方式间的高效耦合衔接是降低旅客出行成本及提高出行便捷程度的重要途径。The accessibility of railway passenger transport stations and networks in urban agglomeration is closely related to the convenience of intercity travel for passengers.Firstly,based on the complex network Space-P modeling method,this paper first studied the actual travel time and cost of intercity passengers to establish a directed and weighted intercity railway passenger transport network in urban agglomeration.Secondly,on the basis of the intercity network,the urban public transport transfer between stations was considered,and the transfer time and cost between stations were calibrated to establish a coupling network.Thirdly,the average shortest travel time,the average lowest travel cost,and the average lowest comprehensive travel cost were used to evaluate the accessibility of the nodes and networks in terms of travel time,travel cost,and comprehensive travel cost.Finally,the railway passenger transport network in Chengdu-Chongqing Urban Agglomeration was studied.The results show that the accessibility of travel time,travel cost,and comprehensive travel cost of the coupling network is respectively increased by 5.45%,11.89%,and 8.23%compared with that of the intercity network.Promoting efficient coupling and connection between different modes of transportation is an important way to reduce travel costs and improve travel convenience for passengers.
