Research On Travel Route Selection Of Passengers Based On Air-rail Composite Temporal-spatial Network

Air-rail combined transportation is the inevitable result of the continuous development of high-speed rail and aviation.More and more passengers tend to prefer air-rail combined transportation products when traveling in medium and long distances,which makes the active cooperation between high-speed rail and aviation more and more important.At present,China’s air-rail combined transport is in its initial stage,and most air-rail combined transport products are only the superficial combination of "high-speed rail + aviation" operation mode,lacking in-depth consideration of passenger travel demand.Therefore,this paper focuses on the travel route choice of passengers in the air-rail composite space-time network.Considering passengers across the city of long distance travel process,on the basis of building space-time-three dimensional transportation empty tin compound time-space network,based on regret minimization rule,proposed to consider the heterogeneity and travel characteristics of heterogeneous route choice model,under different passenger travel in different scenarios to effectively explain the path selection of heterogeneity,Explore the travel needs of passengers more truly,help the supply of high-quality air-rail combined transportation products,and promote the development of modern comprehensive transportation system.The main work of this paper includes:(1)Construction of air-iron composite space-time network.Analysis of the whole process of passenger travel,pay attention to the building before transferring and empty tin compound after the transfer,process the connection through physical topology of the network,with the introduction of time dimension,the space node,arc expand space for time and space,time and space of arc,so as to build the empty tin compound time-space network,and put forward effective path from the Angle of time space double filtering rules,ultimately determine the effective path of time and space.(2)Behavior analysis of passengers’ route choice.Based on behavioral decision theory,the behavioral framework of path choice is constructed and the influencing mechanism of influencing factors and decision rules on choice results is analyzed.Comparison based on rules and regret the choice of the utility model,the model theory,the decision making process,and the calibration of actual case revealed based on the bounded rationality theory of generalized regret minimization model can better depict passengers’ choice behavior,considering both the generalized random regret minimization model is insufficient,the introduction of weber’s law to improve.(3)Path choice model construction based on regret theory.Consideration of psychological factors such as passenger perception attitude on the result of the path selection,MIMIC model is set up to quantify different travel modes passenger psychological latent variables,the psychological latent variables after quantitative as decision variables,and the personal factor,travel characteristic factors and the path of the original features with introducing the improved generalized random regret minimization model,Thus,a route selection model considering passenger heterogeneity and trip characteristics heterogeneity is established.The path choice behavior experiment was designed to calibrate the path choice model constructed in this paper,and the calibration results were compared with the benchmark model to verify the effectiveness and superiority of the model built in this paper.(4)Case study of Dandong-Nanjing travel scenario.Based on the route choice model constructed in this paper,a practical travel scenario between Dandong and Nanjing is taken as an example to explore the heterogeneity of passengers’ choice under different travel characteristics when facing different travel routes in the air-rail composite spacetime network.This paper includes 20 figures,34 tables and 66 references.
