Past studies mostly used the latent class model with the multinomial logit formulation to explore market segmentation. In the existing literature, two types of the latent class nested logit models have been developed to relax the independence of irrelevant alternatives property that imposes the restriction on the multinomial logit. This study aims to apply and compare two alternative latent class nested logit models to examine market segmentation of access modes for high speed rail. The result shows that the latent class nested logit model that is not fully consistent with utility maximization has a higher goodness-of-fit than the latent class nested logit model that is fully consistent with utility maximization. The nested logit models indicate that shuttle bus shares the common unobserved component with city bus and train and these access modes are highly substituted. The study suggests the shuttle bus should have good service quality in order to attract high speed rail passengers to use this access mode.
