Research On On Urban Rail Transit Intermodal Fares

Rail transit is gradually developing systematically.The shared transportation mode has become an effective supplement to the public transportation system in cities,and the travel mode of travelers has shown diversity and combination.For medium and long-distance travelers,the "Metro +" interline travel mode has become the preferred choice.Based on the behavior analysis of transfer-travel users,this paper designs the urban rail transit fare packages combined with the integrated payment concept of MaaS(Mobility as a Service).And the Nested Logit model is established to quantitatively analyze the influence degree of various factors on the effectiveness of users’ choice of fare packages.Firstly,this paper summarizes the travel characteristics of the existing typical intermodal modes of urban rail transit.It is clarified that the three types of factors for "Metro +" interline travel behavior are the traveler’s own attributes,travel attributes and transfer characteristic attributes,including travel distance,travel cost,travel convenience,comfort,economy and other important attributes.Combined with the RP questionnaire data and attribute cross-analysis,it is concluded that there is a correlation between income level,travel distance,travel purpose,travel time period and comfort,economy and subway transfer travel mode.Secondly,combined with the theoretical basis of random utility,a binary Logit model is established to quantify the influence of each attribute characteristic variable of "whether to choose the " Metro+ "interline travel".It is concluded that travelers have high travel costs,high price perception,and a strong sense of identification with economic factors be more likely to switch from not choosing interline travel to “Metro+” interline travel.Further,in the selection of "Metro+" intermodal travel groups,MNL(Multinomial Logit model)is established to determine the impact of the selection of "Metro + Bus","Metro+ Shared bicycles" and "Metro+ Onlinecar-hailing".The conclusion shows that the interline fare package or travel cost discount has a positive attraction to the subway transfer travel utility.Then,this paper integrates the existing fare formulation rules of urban rail transit,bus,shared bicycle and Onlinecar-hailing,and summarizes the form and structure of typical Maas fare system in typical cities at home and abroad.And this paper sorts out influencing factors,preferential forms and ticket types of the existing ticket system,which provides a theoretical basis for the design of the subway intermodal fare package.Finally,based on the quantitative results of the model,the distance scenario is subdivided into short distance,medium distance and long distance.Combined with the existing fare rules of "pricing by distance",a subway intermodal fare scheme based on the concept of payment integration is designed.Combined with SP survey,a hierarchical Nested-Logit model is established to analyze the influencing factors of travelers’ choice of fare packages in various scenarios.The conclusion shows that students or elderly groups with unstable travel frequency tend to choose low-cost and short-cycle weekly tickets.Low-and middle-income people refuse to pay high fares,and tend to choose low-priced tickets with moderate discounts and moderate number of rides.Commuters who have commuting needs and have a stable frequency have a significantly higher probability of purchasing a monthly pass than other users.Combined with the results of the fare discount offer sensitivity analysis,medium-distance intermodal trip users are significantly more sensitive to metro intermodal fare offers than short-distance intermodal trip groups.
