摘要
应用Logit模型对城市轨道交通网络的客流分配问题进行了理论建模,并通过实际调查数据标定模型中未知参数。在路径搜索方面,提出了一种基于深度搜索优先和分支界定思想的有效路径搜索算法,以得出符合现实的有效路径集合。旨在提出一套通过地铁IC卡数据得到轨道交通网络站间OD矩阵后,在轨道交通网络上分配乘客流的模型和算法。通过北京市轨道交通网络实际调查数据的案例分析,对模型和算法的有效性进行了验证。
The paper models theoretically the passenger flow distribution of urban rail transit network using the Logit model and determines the parameters of the model in accord with data obtained from surveys and investigations.It also proposes an effective path searching algorithm based on in-depth search priority and branch bound method to fit more closely the set of effective paths to practical needs.After establishing the OD matrix of the stops of the rail transit network on the basis of data obtained from the usage of IC cards,it puts forth the model and algorithm for the distribution of passenger flow across the network,whose validity is proven in a case study on the Beijing rail transit network.
