Travel Selection Behavior Analysis Of The 3rd And The 4th Generation Sharing Bike Users

Travel behavior choice is the premise and foundation of urban traffic planning and policy formulation.With the rapid development of “Internet +”,travel mode has been changing.In recent two years,sharing bike system has become an important choice to solve the "last mile" trip.In order to further improve the public transport system and better meet the travel needs of different groups in urban transport construction and planning,it is necessary to study the travel characteristics and mode selection behavior of the third generation shared bicycle(public bicycle)and the fourth generation shared bicycle(shared bicycle).Based on the development of research methods,data survey,research objects and development of travel modes at home and abroad,this paper defines the basic connotation of travel,analyses the formation process and response process of travel behavior,and introduces the subjective psychological attribute of attitude perception,which together with traditional individual,family and travel attributes constitutes a set of factors affecting travel choice behaviour,which laid the foundationof the model of public bike and sharing bike users’ travel mode selection and the analysis of travel characteristics.Secondly,by introducing attitudes to perceive latent variable attributes,combinating the structural equation model(SEM)and multinomial logit model(MNL),a discrete travel mode selection model based on SEM-Logit is established,which can take into account both objective factors such as traditional individual,family,travel and subjective factors such as attitude perception latent variables.In order to obtain the basic data sample,through designing the investigation plan and content,the random travel survey of public bicycle and sharing bike users in Yanta District of Xi’an was conducted by RP/SP method.Then the descriptive statistics and comparison of the basic information survey data were made,and the characteristics of the travel mode selection of public bicycle and shaing bike users were preliminarily analysed,then some travel rules were summarized.Finally,based on the sample data,using the established SEM-Logit travel mode selection model,the travel mode selection behavior of public bike and sharing bike users in Yanta District is studied,and the fitting results of the model are tested.The results show that the model is well interpreted.Finally,the choice behavior of sharing bikeusers is analyzed and studied.Meanwhile,the travel mode selection characteristics of public bikee and sharing bike users are clarified.
