Abstract: Shared parking is of great significance in solving the problem of urban traffic parking. To analyze the factors influencing the choice behavior of urban shared parking users, a hybrid-based multinomial choice model was constructed. The upper layer of the proposed model extended the technology acceptance model by introducing three latent variables such as the perceived risk, knowledge level and service quality. The structural equation model was used to analyze the structural relationship and path significance between each latent variable and verify the hypotheses proposed by the model. The latent variables and social attribute variables estimated by the upper level were brought into the lower-level multinomial Logit model and the model parameters were also calibrated. The research results show that the latent variables of parking users, the personal and household attributes and the parking characteristics all have significant influence on users' choice of shared parking. Compared to roadside parking, shared parking is more attractive to users in terms of service quality and safety, but its advantages are not obvious compared to the specialized public parking lots.
