Due to the simplicity and convenience of logit model, it is widely used in the field of economics and transportation. However, the precondition that the random term should be independently and identically distributed, limits the scope of its application. Focusing on the problem above and based on the good characteristics of logit model, this paper probes into its ameliorating mechanism by way of introducing the Function G(y), and studies the inherent relations between the multinomial logit(MNL) model, the nested logit (NL) model and the cross-nested logit (CNL) model, which reflects the theoretical advantages of the CNL model in dealing with the discrete choice problems. At length, the advantages and defects of the three models are compared through an example of the engineering case. The result indicates that the CNL model is more suitable for the trip mode selection than the others.
