Condominium Residents’ Attitudes toward Car-Adoption Intention: A Case Study of Car Parking Space Reduction in Condominiums near Urban Rail Transit Stations in Bangkok, Thailand

This research examines the factors influencing car-sharing adoption intentions among condominium residents near Bangkok’s public transit stations. Car-sharing, a cost-effective and sustainable alternative to private car ownership, is gaining global traction, particularly in rapidly motorizing cities. With rising car ownership posing significant challenges, promoting shared mobility has become a critical strategy for urban management. High-rise condominiums near transit stations are encouraged to reduce parking spaces and promote car-sharing, which can lower construction costs and make residential units more affordable. Understanding residents’ attitudes is essential before advocating car-sharing to real estate developers. To gather insights, data were collected via a questionnaire survey of 237 condominium residents, and Structural Equation Modeling (SEM) was employed to analyze adoption intentions. The analysis focused on key factors such as attitudes toward car-sharing, subjective norms (SN), and perceived behavioral control (PBC). The findings reveal valuable opportunities for developers and urban planners to effectively integrate car-sharing initiatives. Attitudes toward car-sharing, particularly perceptions of service quality, emerged as the most significant factor influencing adoption. Conversely, perceived behavioral control such as challenges in finding parking or traveling long distances was identified as the primary barrier discouraging car-sharing use. Environmental concerns (EC) also played a role, with environmentally conscious travelers typically opting for other forms of public transportation. However, interest in car-sharing increased among this group when electric vehicles were offered, highlighting the potential of eco-friendly options. Interestingly, subjective norms, or social influence, had little impact on car-sharing adoption intentions. These findings suggest that addressing practical barriers—such as improving accessibility and service quality—and promoting environmentally friendly electric car-sharing options are key strategies to encourage adoption. Such an approach can help reduce dependency on private cars, alleviate congestion, and support sustainable urban mobility by offering affordable, efficient, and eco-conscious transportation alternatives.
