出行者对出行方式的主观评价和出行者异质性对出行选择行为都具有重要影 响． 文中利用潜在类别选择模型研究这些因素对出行选择行为的影响． 通过验证性因素分 析，得到出行者对出行方式的舒适性评价和可靠性评价等潜在心理变量． 将潜在心理变量 带入潜在类别条件 Logit 模型中，研究出行者可以划分的潜在类别数量，并研究不同潜在 类别的出行者在时间价值、拥挤度评价、可靠性评价方面的异同． 研究结果表明，出行者可 以划分为 Class1、 Class2 两类群体，其中 Class1 在出行行为选择时，考虑出行方式的舒适 性和可靠性，时间价值较低;而 Class2 在出行行为选择时，不考虑出行方式的舒适性和可 靠性，时间价值也显著高于 Class1． 文中定量化的研究结果可用于公共交通设施的规划设 计与评价． 

 Travelers' evaluation on travel mode and heterogeneity of travelers have significant impacts on travelers' choice of travel mode． These impact on travel mode choice were analyzed with the latent-class conditional logit model． Through the confirmative factor analysis，travelers' latent psychological variables，that is，subjective evaluation of travel mode's comfort and reliability，were obtained． The similarities and dissimilarities of in-vehicle time of value，comfort evaluation and reliability evaluation between different latent classes were analyzed by incorporating these latent psychological variables into the latent-class conditional logit model． The study shows that travelers could be divided into two subgroups ( class 1 and class 2) ． On choosing travel mode，travelers in class 1 consider the comfort and reliability of travel mode and have a low value of travel time; while travelers in class 2 don't consider comfort and reliability of travel mode，and have a higher value of travel time than travelers in class 1． The estimated willingto-pay can be used in planning and evalution of the public transportation．
