Abstract: Different types of bus users have different opinions on public transport and their willingness to use public transport． Different types of bus users have different opinions on public transport and their willingness to use public transport． Based on bus users’satisfaction and their traveling behavior，bus users were classified with the latent class regression model． Then based on the classification，factors that affect the overall satisfaction and the willing- ness to traveling by bus were analyzed among different subgroup． This result shows that bus users can be classified into two subgroups: the occasional bus users and the loyal bus users，and that private car ownership and income have a great influence on the classification． That is users with private car are more likely to be occasional bus us- ers，and along with income increases，the user is more likely to be a occasional bus user． The analysis result of factors affecting satisfaction shows that the evaluation on bus speed，time reliability，waiting time and ticket price have stronger influence on occasional bus users’overall satisfaction than that on loyal bus users’． As to the effect of recommendation to use bus，it is found that the overall satisfaction of occasional bus users significantly affect the recommendation effect，and the recommendation effect increases as the overall satisfaction increases． Also，travel- ers’traveling by bus decreases after they have private cars and the occasional bus users’frequency of traveling by bus increases as the overall satisfaction increases．
