Research On Service Satisfaction And Site Selection Method Of Car-sharing Depots

With the rise of the “sharing economy” and the advent of the Internet era,shared travel has also entered people’s vision.As a form of shared travel,shared cars can meet the driving needs of the group to be driven,and achieve optimal allocation of social resources;but shared cars are still in the development stage,there are some imperfections in the development,such as "difficulty in picking up the car","difficulty in returning the car",etc.Research on service satisfaction and site selection method of Car-sharing depots can provide a basis for the layout of car-sharing companies’ operating depots,and make user travel more convenient.The main research contents of this paper are as follows:(1)Research on service satisfaction of car-sharing depots.Use the 5-point Likert scale to design questionnaires,and then data collection was carried out.Based on the obtained questionnaire data,a preliminary analysis of personal attributes and user-perceived car-sharing depots service satisfaction was conducted.Construct a service satisfaction evaluation model for car-sharing depots based on the Rasch model,fit the data to the Rasch model,then estimate project parameters,and analyze users’ satisfaction with car-sharing depots services.The research show that users’ satisfaction with the observed variables of car-sharing depots services from high to low is the overall feeling> convenience of depots > coordination of depots > price perception,and there will be significant differences in the user’s individual abilities and perceived project difficulty with different attributes.(2)Research on site selection method of car-sharing depots.Based on the evaluation results of users’ satisfaction with car-sharing depots service,car-sharing depots coordination can affect the user’s travel experience,the site selection method of car-sharing depots has been studied to improve coordination.Propose a preliminary screening method for car-sharing depots based on the characteristics of the Voronoi diagram,then establish a multi-objective location optimization model for car-sharing depots with taking the minimum investment cost of the enterprise and the minimum walking cost of the user as the optimization objective,which combine spatial screening and multi-objective location selection model.Take the Lianhu District of Xi’an City as an example to verify site selection method of car-sharing depots.The research results show that the demand points covered by the V polygon generated with each car-sharing depots as the control point are consistent with the demand points covered by each car-sharing depots calculated by the model,which verifies the feasibility of the model.
