Abstract:  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． 

Key words: travel mode choice, heterogeneity, latent-class conditional, Logit model, comfort, reliability
