Rapid urbanization has posed numerous challenges for major cities around the world, with a critical issue being the shortage of adequate parking spaces. As reliance on private vehicles has increased, the availability of parking spots has not kept pace. Consequently, drivers often spend significant time searching for parking, which leads to higher carbon emissions. To address this problem, the concept of shared parking services has emerged. Shared parking apps allow citizens to act as both providers, offering their unused parking spaces, and consumers, utilizing available spaces when needed. This dual engagement creates a new concept known as "prosumers." Prosumers not only intend to share their parking spaces but also intend to use the spaces of others. However, current urban planning does not adequately reflect the behavioral intentions of prosumers, treating them as if they are the same. Recent research in behavioral economics indicates that prosumers may have different intentions when it comes to sharing their own parking spaces compared to using others'. Additionally, these intentions are influenced by various factors. Understanding these differences is essential for planning sustainable shared parking services. This study aims to investigate the behavioral intentions of prosumers regarding shared parking services. We conducted a web-based survey targeting prosumers who have actively participated in the service as both providers and consumers. To deeply understand prosumers' intentions, we have developed model frameworks based on the extended theory of planned behavior, incorporating perceived risk theory. We hypothesize that socio-demographic variables and land use factors significantly affect these intentions. Our findings reveal a notable trend: prosumers exhibit a generally lower intention to share their parking spaces compared to their intention to utilize the parking spaces of others. Furthermore, our analysis indicates that various dimensions of perceived risk significantly influence prosumers' behavioral intentions to either share their own parking spaces or to use those offered by others, but these effects manifest in distinct ways. For instance, perceived performance risk has emerged as the most significant factor affecting the intention to share parking spaces. This is particularly evident among older and female prosumers residing in city centers, who may have heightened concerns about the reliability, safety, and quality of the shared parking experience. Such concerns could stem from the potential for damage to their property or the apprehension about the security of sharing their spaces with strangers. On the other hand, perceived financial risk plays a crucial role in shaping prosumers' intention to use the parking spaces offered by others. This is especially pronounced among low-income individuals living in neighborhoods where shared parking availability is limited. These individuals may be particularly sensitive to costs associated with parking, fearing that they could be overcharged or that the pricing might not align with their budgetary constraints. The financial considerations surrounding this risk factor can significantly deter them from utilizing shared parking services offered by their neighbors. Given these insights, we propose several actionable strategies that urban planners can implement to enhance the effectiveness and sustainability of shared parking services.
