With the rapid growth of the number of cars and the acceleration of urbanization,the contradiction between the parking system and the scale of cars is becoming more and more obvious.Park-and-Ride(P+R)mode can alleviate parking and traffic pressure to some extent.In this paper,Xi'an Park-and-Ride system is taken as the research object,and a questionnaire is designed by using the 5-point Likert scale to obtain data,and an evaluation model of park-and-ride service satisfaction based on the Rasch model is constructed.The data are fitted to the model,and the project parameters are estimated and the satisfaction of Xi'an Park-and-Ride service is analyzed.The research results show that the data are well fitted to the model,and the overall users are satis-fied with the park-and-ride service.
