Abstract: Carpooling is emerging as a more appealing “sharing economy” form with promising benefits in reducing carbon emissions, traveling costs, and traffic congestion. However, a thorough understanding of carpooling adoption for commuting trips is lacking for policymakers and transport planners in developing countries due to limited scientific research, specifically in Southeast Asia. Therefore, the present study aimed to understand the determinants and behavioral influence of carpool adoption for tertiary educational trips in Thailand by conducting a multivariate analysis on a dataset of 307 observations gathered at Thammasat University, Pathum Thani, Thailand. A conceptual model was developed primarily based on the Consumer Acceptance and Use of Information Technology (UTAUT2) model with modifications of replacing habit construct with perceived safety and adding two additional constructs related to COVID-19 and time credits. The sample data were analyzed using Structural Equation Modelling (SEM). It was found that hedonic motivation, social influence, and time credit factors play statistically significant roles in the intention to use carpool for tertiary educational trips, while effort expectancy, perceived safety, and perception towards COVID-19 and carpool do not. Further, hedonic motivation mediates the effect of social influence and effort expectancy. Through multigroup analysis, it was identified that hedonic motivation and time credits factors are highly significant for motorized mode users compared to active mode users. Furthermore, SEM with interaction terms revealed that social influence and time credits factors could be used to attract people who drive cars towards carpooling even though they are less inclined to carpool. Also, hedonic motivation and social influence factors can be used to attract people who live closer to their school. Upon analysis of the findings, policy implications are presented that can be used to improve carpooling adoption for educational trips in Thailand
