Research On Ticket Income Distribution Model Of Urban Rail Transit Based On Improved Logit Model

Urban rail transit has become the mainstay of the current public transportation system in the city because of its large volume,fast speed and timeliness.However,the construction of urban rail transit is huge,and it is difficult to achieve a balance between input and output in a short period of time.It is difficult to support the normal construction and operation of a certain-scale urban rail transit network by relying solely on government subsidies or single investors and operators.Therefore,the construction and operation of an urban rail transit network may involve multiple investors and operators,which in turn involves the issue of ticket income distribution during operations.In the context of the widespread adoption of one-vote transfer in the country,when the multi-path problem occurs,the system cannot identify the specific path of the passenger,and multiple valid paths between a pair of OD are selected.Different paths involve not only different routes,but also different paragraphs and different operators and investors.At this point,a reasonable distribution of the ticket revenue becomes critical.This paper first introduces various types of ticket system for urban rail transit,and analyzes the rationality of the principle of counting and decreasing rate with increasing distance,and uses this as one of the background conditions for this study.At the same time,it is pointed out that in the multi-path problem,different paths will go through different paragraphs,and different paragraphs may belong to different investment subjects.It's the main problems studied in this paper.Then the influencing factors of passenger route selection behavior based on ticket distribution are analyzed,and the path generalized cost function applicable to the ticket clearing model is given.At the same time,the questionnaires of passengers' path selection behavior were investigated,and the conclusions of the passengers' travel basis and main influencing factors with different familiarity of the path were obtained,which provided a theoretical basis for the application of the subsequent multipath probability model.Secondly,the applicability and practicability of the traditional effective path algorithm are compared and analyzed,and the traversal algorithm based on key nodes is established.Then it analyzes the multi-path problem in the urban rail transit road network structure and operation model,which is used as the key point of ticket distribution.Then based on the defects of the traditional Logit model,an improved Logit model based on path scale is proposed for ticket clearing.Finally,based on the ticket distribution process,the effective path screening algorithm in the preceding paragraph,the generalized cost function of the path and the multipath probability selection model,the complete ticket clearing model of urban rail transit is finally proposed.Based on the existing road network in Xi'an,the case analysis is carried out to verify the feasibility and practicability of the model,and the recommended ratio of partial OD is given.
