Study On Passenger Flow Distribution Method Of High-speed Railway Considering Time Factor

With the improvement of people’s living standards and the vigorous development of the railway transportation industry,railway passengers have higher and higher requirements for railway transportation travel time.In this case,can the railway transportation supply well meet the time demand of railway passengers? It has also become an important indicator for evaluating the rationality of railway transportation organization.For this reason,based on the time factor,this paper starts to meet the travel time demand of passengers,and conducts research on the passenger flow distribution of high-speed railways,so as to obtain the passenger flow distribution results that are more in line with the actual needs,provide support for the optimization of the travel plan,and improve the railway transportation industry.Service capabilities.The main work of the thesis includes:1.Analyze and summarize the main influencing factors of railway passenger travel from the aspects of economy and society,characteristics of transportation facilities,traveler characteristics and travel characteristics,etc.,and introduce two survey methods,RP and SP,to lay the foundation for the investigation and analysis of passenger travel behavior in the following sections.2.The definition of time elements is introduced,and the research on passenger flow distribution methods is carried out based on time elements such as departure time,arrival time,travel time,stop time,transfer time and so on.The travel behavior information of passengers of different genders,ages and incomes is collected through questionnaires,and after statistical analysis of the questionnaire data,the sensitivity of travel time risks of different passengers is calculated,and the travel time window range of passengers is determined.The search algorithm of reasonable path set is regarded as an important part of the research of railway passenger flow distribution method.3.The stochastic utility theory is introduced,and the travel time,transfer time and deviation from expected departure and arrival time are used as the influencing factors for passengers to choose the travel route in the reasonable route set,and the generalized cost function of the travel behavior of passengers is established.The multi-layer Logit model is used to determine the probability of passengers choosing each ride route in the reasonable route set.According to the selection probability of each route,the passenger flow allocation is completed by the incremental allocation method.At the same time,the principle of passenger flow allocation is determined,and a complete passenger flow allocation method is proposed..4.Taking the passenger flow in the downward direction of the Beijing-Shanghai high-speed railway line as an example,on the Beijing-Shanghai high-speed railway line,according to the method proposed in the article,the programming software was used to distribute the passenger flow.The passenger flow distribution results are analyzed and summarized,and the model parameters are subjected to sensitivity analysis.
