基于网络均衡的城市客运枢纽换乘需求研究

Research on the Transfer Demand in Urban Public Transportation Terminal Based on Network Equilibrium

城市客运枢纽作为综合客运交通体系的重要组成部分,其基础内容就是研究枢纽的换乘需求.将交通网络抽象为分层网络,在随机用户网络均衡理论基础上,分析城市交通网络中出行者的出行方式选择行为,构造出行费用函数,提出了相应的变分不等式模型和枢纽换乘流量的计算方法.根据城市出发地目的地数据,通过外部变量的变化,得到城市客运枢纽换乘需求的变化,并对这些变化加以分析,以期改善客运枢纽的换乘能力.最后结合一个算例,研究了外部变量的变化对城市客运枢纽换乘流量需求的关系,验证了方法的可行性.研究结论为城市客运枢纽换乘需求研究提供有益的参考.

As one of the most important components of the transportation system, the urban public transportation terminal is essentially researched by the transfer demand. In this work, the traffic network was abstracted as a hierarchical network. Based on the network equilibrium theory, the traveler＇s behavior of choosing travel mode was analyzed. The variational inequality model and the calculation method of transfer demand were presented. According to the data of O （origin）-D （destination） matrix and the changes of external variables, the changes of terminal transfer demand can be obtained and these changes were analyzed for improving the transfer efficiency. Finally, a numerical example was studied and the relationship between the changes of external variables and transfer demand in terminal was explored. The result has verified the feasibility of the proposed calculation method. This research could provide a useful reference for research on the transfer demand in urban public transportation terminal.
