Research On Multi-mode Cooperative Operation Evaluation Of Ground Transportation Center In Airport Hub

With the rapid increase in the passenger throughput of air transportation,the evacuation efficiency of the airport hub is facing serious problems.The travel structure of the ground transportation centers in most of my country’s airport hubs is unreasonable,and the public transportation passenger flow sharing rate is too low,resulting in road congestion and reduced passenger service levels.Therefore,it is particularly important to evaluate the multi-mode coordinated operation level of the airport hub.This paper studies the multi-mode coordinated operation evaluation of the ground transportation center of the airport hub.The main contents of this paper are as follows:(1)Based on the basic concepts,relevant connotations and principles of constructing an evaluation index system for the evaluation of coordinated operation of multiple transportation modes,through the literature survey method,considering the three perspectives of society,operators and passengers,the airport hub ground transportation center has been constructed.The evaluation index system is operated in a coordinated manner.The criterion layer includes three aspects: capacity coordination,transfer coordination and service coordination,and the index layer includes 13 evaluation indicators.Based on the principle of coordinated operation of multiple transportation modes,this paper gives a quantification method for evaluation indicators;according to relevant national standards,industry standards and reference documents,gives a grading standard for rating indicators.(2)The application scope,advantages and disadvantages of commonly used evaluation methods and five-element connection number method are introduced in detail.After comparative analysis,the five-element connection number suitable for the research content of this article is selected.(3)The weight assignment method combining subjectivity and objectiveness is adopted,that is,the attribute hierarchy(AHM)is used to determine the index weight of the criterion level,the entropy weight method is used to determine the index weight of the index layer,and the five-element connection number is used as the evaluation method to construct the airport hub.The multi-mode cooperative operation evaluation model of the ground transportation center outputs and analyzes the evaluation results,including situation analysis,trend analysis,and judgment evaluation level.(4)Take the Capital Airport T3 terminal as an example,according to actual data(mainly derived from related projects of the Capital Airport,announcements and documents issued by relevant transportation departments,and field surveys),use MATLAB software and use the airport hub constructed in this article The multi-mode collaborative operation evaluation model of the ground transportation center processes and analyzes the data to obtain the evaluation results.Comparing the evaluation results with other commonly used evaluation methods proves the reliability and feasibility of the model in this paper.
