Exploring Day-to-day Variations in the Bus Usage Behavior of Motorcycle Owners in Hanoi

This study attempts to explore the day-to-day variations of motorcycle owners’ bus usage behavior and situational factors influencing their mode choice in Hanoi where the motorcycle is a dominant mode. To distinguish which types and how many of the variations can or cannot be captured, we used a multilevel binary logit model which can deal with both observed and unobserved inter-individual and intra-individual variations. In our empirical analysis, we used data from a one-week travel diary of 55 motorcycle owners. The results indicate that the variations of motorcycle owners’ bus choice behavior depend much on intra-individual variation which could partly be represented by the variables related to accompany person(s), travel distance, and the complexity of the tour.
