Research On The Carsharing Choice Behavior Based On Subway Park And Ride

The rapid increase of vehicle ownership has brought a series of traffic problems such as traffic congestion and parking difficulties.As one of the travel services to effectively alleviate traffic problems,carsharing has entered people’s life.However,high travel costs and parking difficulties in urban centers limit the development of carsharing.The combination of carsharing and subway travel can not only make up for the shortage of carsharing in travel cost and parking,but also give play to the advantages of convenient and flexible carsharing.The purpose of this study is to study the carsharing choice behavior based on subway park and ride.Firstly,the modeling method of carsharing choice behavior based on subway park and ride and the influencing factors of carsharing choice behavior based on subway park and ride are summarized by analyzing the research status at home and abroad.Secondly,questionnaire design,field survey and statistical analysis of survey data are conducted according to the selected influencing factors.Finally,the variables were filtered and set to build a multi-logit(MNL)model,an Nested Logit(NL)model considering the characteristics of carsharing public transport and an NL model considering the characteristics of carsharing private transport;STATA software was used to estimate the parameters of the model constructed,and the results of parameter estimation of NL model considering different attributes of carsharing were compared to explore the dual attributes of carsharing;At the same time,according to the results of model parameter estimation,this paper analyzes the influencing factors of the traveler’s choice of carsharing based on subway park and ride and puts forward some Suggestions on the promotion of carsharing and carsharing based on subway park and ride.The results of the research show that carsharing has more similar characteristics to private transportation.Travelers aged 36-60,without a driver’s license,couples with children and in need of transportation tend to choose carsharing based on subway park and ride.Travelers with junior college,technical secondary school,bachelor’s degree,master’s degree or above,annual family income above 250,000,family car ownership are not inclined to choose carsharing based on subway park and ride;The parking cost near the workplace and the tolerable average speed of the central area have significant positive influence on the choice of carsharing based on subway park and ride.The time on the vehicle has a significant negative effect on the choice of carsharing based on subway park and ride.The comfort level has a significant positive influence on the choice of carsharing based on subway park and ride.The research on carsharing choice behavior based on subway park and ride can provide theoretical basis for formulating corresponding carsharing promotion policies and measures,and at the same time,it can alleviate urban traffic problems such as traffic congestion,parking difficulties in urban centers,and environmental pollution to some extent.
