Travelers' level of satisfaction is an important performance measure for transport service providers and a determinant of mode choice. However, its computation is not easy because of the complicated and unique characteristics of travelers. The traditional method of comparing yearly satisfaction percentages has been implemented in several places; however, it does not include the interrelationships between variables that determine satisfaction. This study estimates travelers' level of satisfaction using an ordered logit model and then uses the results in a binary mode choice model. The results show that the level of satisfaction has a significant influence on the modal choice characteristics of travelers.
