为解决城市轨道交通线网内乘客出行路径难以确定的问题,本文针对以往研究不足之处,全面选取出行者特征属性、出行特征属性及路径特征属性作为研究变量,构建了考虑乘客有限理性及选择偏好异质性的路径选择模型。采用序列正交法生成SP调查问卷,以通勤客流为研究对象在成都市开展路径选择行为调查。基于调查数据对模型标定,分析了影响因素的显著性、异质性以及正负向性,最后将本文建立模型与以往研究建立模型进行对比,从拟合优度及预测效果两方面验证了本文模型的有效性。

To solve the difficulty of determining the passengers' travel routes in the urban rail transit network, this study aims to solve the shortcomings of previous studies, and comprehensively selects the passengers' characteristic attribute, travel characteristic attribute and path characteristic attribute as the research variables to develop a route selection model. This model takes the passengers' bounded rationality and heterogeneity of choice preferences into account. The route choice behavior of commuter flow in Chengdu has been investigated by utilizing stated preference questionnaires, that are generated by the sequence orthogonal method. Based on the pros and cons the survey data, the model is calibrated, and the significance, heterogeneity, and of the influencing factors are analyzed. Finally, by comparing the proposed model with the models discussed in previous studies, the validity of the current model is verified from the two aspects of goodness of fit and prediction effect.
