The idea of sharing economy on fully utilizing idle resources matches well with the concept of sustainable development that prevails across the world. The applications of sharing economy in transportation, such as carpooling, car-sharing, bike-sharing and shared parking, have generated positive effects on transportation systems and become the important directions and trend for promoting green transportation in the world. The shared parking model has recently been promoted in Taiwan. The success of implementing shared parking models depends on the intension-to-use of the public. Hence, it is very important to investigate the factors which affect people’s intention to use the shared parking.
Previous studies on behavioral theories have primarily focused on users’ behavioral intentions from the demand side. However, both parking space users (demand) and providers (supply) are indispensable to a shared parking model, so the supply and demand sides play an equally important role, Given this rationale, the success of a shared parking model hinges on the matchmaking between parking space providers and users. In light of literature review, this study adopts a combination of the Technology Acceptance Model and Theory of Planned Behavior (C-TAM-TPB) as a theoretical framework to investigate people’s intension to use the shared parking from both supply and demand sides. In this theoretical framework, seven research hypotheses are established and the corresponding constructs and questions are developed to design the questionnaire for collecting data to conduct the empirical study. The valid sample size is 549.
The theoretical framework and hypotheses was examined using the partial least-square (PLS) method of structural equation modeling (SEM). The results validated the hypotheses proposed in this study. The constructs “Perceived Behavioral Control” and “Subjective Norms” are the most important factors for parking space users and providers, respectively. Moreover, the construct “Attitude” is an important factor affecting the intension-to-use of shared parking for both providers and users. Multiple-Group Analysis (MGA) has also been performed to divide the respondents into different clusters by age, gender and the experience of using sharing economy. The results indicate that these three variables have moderating effects on the proposed theoretical model. The findings of this study would facilitate identifying the intrinsic factors that could increase the intension-to-use of shared parking for both providers and users, and help government agencies and system operators to promote shared parking to the public.
