| 传统的城市轨道交通网络客流分配方法使用了基于离散选择理论的多项Logit模型，与其相比，巢式Logit模型消除了影响因素的相关性，具有更好的解释能力。介绍了巢式Logit模型的原理及公式，以城市轨道交通网络中乘客的出行行为为研究对象，将乘客选择过程分为换乘次数选择和换乘路径选择两个层次，并以此为构架建立了城市轨道交通客流分配巢式Logit模型。通过实例，利用SAS软件对模型进行求解和分析，从概率角度用定量方法分析出行个体的出行选择行为和轨道交通网络流量分配，对于提高城市轨道交通网络化运营组织水平、进行合理的运能配置和构建城市轨道交通票务清分系统意义重大。 |

| Multinational logit model is usually used in the traffic assignment model of urban railway transit, which is based on discrete choice theory. Compared with it, nested logit model eliminates the influence of correlation factors and has a better explanation ability. This study introduces the principle and formula of the nested logit model. Through the analysis of travel choice behavior and travel utility, this paper establishes nested logit model for the traffic assignment problem of urban railway transit, which divides passengers’ selection process into the selection of transfer times and the selection of transfer path. At last, this paper verifies this model by an example, which is carried out with SAS software. This study analyzes both quantitatively and qualitatively the individual travel choice behavior and the rail network traffic assignment from the angle of probability. It is of great significance to improving the level of operation organization, configuring reasonable capacity and building urban rail traffic ticket distribution system. |
