Research On The Coordinated Development Of Passenger Transport Structure Of Comprehensive Transport Corridor Under Regional Transportation Integration

Regional transportation integration is an indispensable and important link for regional economic development,and its transportation manifestation and development pattern determine the upward space and long-term layout of regional economic development.The most important decision to achieve regional transportation integration is to ensure the stable,orderly and coordinated development of the passenger transport structure of the comprehensive transportation corridor.The comprehensive transportation corridor is the backbone of the entire transportation system,and it is responsible for the main circulation tasks of regional passenger and freight transportation.The coordinated development of its passenger transportation structure can integrate the transportation infrastructure,transportation equipment and other hardware facilities with information technology and other resources,and improve the regional transportation network.The accessibility to maximize the use of transportation resources is conducive to the rapid development of the regional economy.This article starts with the travel mode choice behavior of passengers,analyzes the travel process of passengers in the integrated transportation corridor,and summarizes the factors that affect the travel choice behavior of passengers from the three levels of transportation mode supply difference factors,passenger demand determinants and external environmental factors.Based on this,the sharing rate model of each transportation mode considering the different income levels of passengers and the sharing rate model of each transportation mode without considering the income level were established respectively.The utility function of the first sharing rate model is based on factors such as economy,convenience,speed,safety,comfort and punctuality,giving different factor indicators different weights;the second sharing rate model is in-depth analysis of the above six types After the potential relationship of the influencing factors,the utility function is established based on the three factors of travel cost,travel time and additional time(waiting,transfer,and connection time except for regional operation time),and then the weight of related indicators is determined.Based on the synergetics theory,this paper constructs a coordination model for the passenger transport structure of the regional integrated transport corridor.There is synergy between the travel choice behavior of passengers and the supply-demand relationship,traffic structure and transportation characteristics of transportation modes in the integrated transportation corridor.The share rate is used as the order parameter of the coordination system,and various influencing factors are used as the control variables of the system.Considering the two principles of adapting to the supply-demand relationship of transportation modes in the channel and maximizing the overall operating efficiency of the channel,the objective function of the model is established based on the channel saturation entropy.Combining the constraint conditions of variables,construct the coordination model of regional comprehensive transportation corridor passenger transportation structure,and use the genetic algorithm to solve the nonlinear programming.The overall coordination status of the passenger transport structure is evaluated from the three aspects of the coordinated development of the passenger transport structure subsystem of the integrated transport corridor,between the subsystems and the entire passenger transport system,and the system coordination status evaluation indicators of these three levels are selected in turn.The evaluation result is qualitatively described as "reasonable,reasonable,basically reasonable,unreasonable,and extremely unreasonable";based on the quantitative calculation of membership function in fuzzy mathematics,the evaluation criterion table of the coordination state of the regional comprehensive transportation corridor passenger transportation structure is obtained,according to The principle of maximum degree of membership in the degree of membership matrix determines the evaluation level of the coordination state of the passenger transport structure.On this basis,this article takes the Lanzhou(Lanzhou)West(Xi’an)comprehensive transportation corridor in the land bridge transportation corridor as an example for analysis,completes the relevant data analysis through the software SPSS,uses MATLAB programming,and runs to obtain the calculation results,which verifies the synthesis of this article.The effectiveness of the passenger transport structure coordination model and the solution algorithm of the transport corridor,and the coordination status of the passenger transport structure of the Lanxi integrated transport corridor is obtained as "reasonable".
