Research On The Choice Of Travel Mode Under The Condition Of Car-hailing

With the development of social economy,urban residents travel demand sharp growth,net about car as a new way to travel,after five years of development,to a certain extent changed the structure of urban residents travel,effectively relieves the problem of "difficult to take a taxi",also the traditional cruise taxi and bus system caused a certain impact.In order to better predict and explain the willingness of the traveler to choose the vehicle,it is necessary to analyze the internal psychological factors of the traveler.This paper used the structural equation model(SEM)on traveler choice network about car implicit variables and the variables of associated modeling,studies have shown that traveler perception of network about car reliability,convenience,perceived cost perception,perception of comfort and security perception will to choose the five latent variables will have different degree of influence;Among them,perceived reliability has the greatest influence on choice intention.The study of the key factors of the selection of the vehicle by the traveler provides reference for the selection of the properties of the travel mode in the following different scenes.Then,this paper designs a questionnaire survey of residents' travel mode in commuting and leisure scenes.Considering the reliability of the car-hailing stage compared with the taxi stage,the key attribute of the uncertainty of waiting time is innovatively added on the basis of existing research.In addition,the breakdown time is:the starting point and the site walking time,the expected waiting time and the driving time of the vehicle.Among them,the convenience characteristic of the network is reflected in the shorter expected waiting time.Comprehensive analysis of various kinds of travel time and travel cost and the influence of the personal social economic attribute of travel mode choice,through orthogonal SP questionnaire design and investigation in the field of chengdu and Internet,eventually establish a discrete choice model,multinomial Logit model(MNL)for quantitative analysis of survey data.At last,this paper model analysis results are as follows:(1)In the scene mode choice,each of the means of transportation travel proportion respectively:bus--37.8%?subway-18.5%?car-hailing-5.5%?taxi-3.8%?private car-34.3%.In options properties,cost,all point to the site walk total time,estimated waiting time,waiting time of uncertainty,the car driving time of the four variables of way choice behavior are significant;In the social attribute variables,except for the gender,the three attributes of age,income(except subway)and the ownership of private cars were all significant.(2)In the elastic analysis,transit time property of the lack of flexibility,the improvement of bus travel ratio cannot be confined to time cost optimization,improve the comfortableness and reliability of bus service is the key;(3)The subway inelastic in waiting time,but in all subway stations walking time attribute points to elastic,that reduce the time of the traveler to subway stations,to improve the subway ratio have a significant role;(4)Both the ride-hailing and cruise taxis are flexible in the expected time of waiting and the driving time of the vehicle.That is,the residents choose these two modes of transportation to pay more attention to the timeliness.At the same time,the increase of the uncertainty of the waiting time will lead to the decrease of the choice probability,indicating that the traveler is risk-averse in the waiting time.Cruising taxi on the properties of elastic,when cruising taxi about uncertainties to network traffic,at ordinary times the choice probability is greatly increased,reached the current network about the selection probability of car.Therefore,it is the key to the reform of the taxi industry to improve the reliability of traditional taxi hailing.However,in the case of leisure and entertainment,it is very important to set reasonable travel rates for ride-sharing.
