For sustainable development in the transportation sector: Determinants of acceptance of sustainable transportation using the innovation diffusion theory and technology acceptance model

With global interest in environmental concerns, the importance of sustainable development has consistently increased. With this trend, the concept of sustainable transportation is an urgent issue in both developed and developing countries. Thus, the current study examines user adoption of sustainable transportation and proposes an integrated model of two theoretical frameworks: the innovation diffusion theory and technology acceptance model. The structural results with 250 respondents in Korea find a sequential connection for users' intention to use, while two main determinants of intention-perceived usefulness and attitude-as well as the roles of their environmental knowledge and perceived compatibility, are also highlighted. Based on these findings, both practical and theoretical implications were presented.
