| Under the background of the rapid development of high-speed railway in China,high-speed railway passenger transport hub undertakes the important task of connecting multiple high-speed railway lines to the outside and multiple transfer modes to the inside of the city,which has become an important place for passenger distribution and transfer.However,with the improvement of the high-speed railway network and the increase in the per capita income level,the number of passengers who choose to travel by high-speed rail continues to increase,and the passenger flow arriving at stations within a short period of time has put great pressure on transfers within high-speed rail hubs.It is necessary to study the influencing factors and formation mechanism of the passengers’ choice of transfer mode at the high-speed railway hub.With the purpose of studying the choice behavior of passengers in high-speed railway hubs,this paper firstly analyzes the behavior characteristics and transfer psychology of passengers in different transfer stages,and summarizes the subjective and objective factors affecting the choice of transfer mode.Secondly,based on the theory of planned behavior,an initial hypothesis model of latent variable influencing factors including service characteristics and psychological characteristics was constructed,and combined with survey data of Chengdu East Railway Station passenger transfer selection method,the structural equation model(SEM)was used to analyze Correlation between the service characteristics and psychological characteristics of the four modes of transfer transportation,and the effect of the transfer intention is analyzed,and the results of each latent variable measured by its observed variables are given;Then,the utility function of Multinomial Logit Model(MNL)was improved,and the SEM-MNL integration model of passenger departure transfer mode selection was constructed,which included both latent variables and explicit variables.The parameters of the model are calibrated and tested,and the test results are compared with the selection model without considering the influence factors of potential variables.It is found that the SEM-MNL model constructed in this paper has better explanatory ability and prediction accuracy for the transfer mode selection behavior;Finally,the influence of different characteristic variables on the choice of passenger transfer mode is analyzed.The results show that:(1)The intention of passengers to change subways and buses is mainly affected by attitudes.Passengers who choose subway transfers are more concerned about the fastness and economy of the way,and passengers who choose to commute are more inclined to the economy and convenience of the way;(2)The behavior intention of passengers to transfer private cars and taxis is mainly affected by perceptual behavior control,which indicates that when passengers transfer,they will weigh the relationship between their bearing capacity,economic conditions and related benefits more,and make decisions more rationally;(3)The impact of the hub service environment on subway and bus transfers is significant,mainly because the transfer of these two modes of public transportation requires a tedious transfer process and is more sensitive to the hub service environment;In terms of comfort,passengers are the least comfortable with public transport transfer and the best comfortable with private car transfer. |
