This study attempts to investigate motivations for individual modal shifts of motorcycle and car users for commuting trips in the context of new public transport projects in Ho Chi Minh City. We designed a survey to obtain information on five types of potential motivations, including service quality, social interaction, psychological determinants, situation of roadways, and socioeconomic characteristics. The analyses follow a two-stage approach consisting of a multiple-indicator-multiple-cause model for capturing psychological determinants and a bivariate ordered probit model for explaining the decisions of each user group on usage frequencies of the current buses and the new public transport system. The results show the significance of access/egress time, fare/cost, congestion/comfort, social interaction, agreement to the public transport projects, dissatisfaction with public transport, distance from home to workplace, motorcycle ownership, occupation, and age. Additionally, new public transport usage was correlated with bus usage. Car users were found to be harder to convince.
