Study On Synthesis Comfort Evaluation Method Of Beijing Subway Train And Development Of Evaluation System

With the rapid development of urban rail transit,the situation that insufficient supply of transport services has undergone a fundamental change,and passengers pay more and more attention to the ride comfort of subway trains.How to scientifically and effectively evaluate the synthesis comfort of subway trains and how to timely grasp and analyze the synthesis comfort data of subway trains,thus improve the passenger comfort level through targeted improvement measures are practical problems that relevant managers need to solve.On the basis of relevant literature research results and current standards at home and abroad,this paper pertinently studies the synthesis comfort evaluation of Beijing Subway trains from the following three aspects.(1)The synthesis comfort evaluation system of Beijing Subway and evaluation index calculation model are put forward Synthesis comfort is the result of the physical,physiological and psychological effects caused by various factors in the environment of passengers,and it is a subjective comprehensive index.Based on the actual situation and demand survey results of Beijing Subway,this paper deeply analyzes five influencing factors of the Beijing Subway synthesis comfort,and constructs an evaluation index system of the Beijing Subway synthesis comfort including the highest hierarchy,the middle hierarchy and the lowest hierarchy.On the basis of referring to the relevant existing standards and research literature at home and abroad,the author gives the measurement method and establishes the calculation model and evaluation standard of nine lowest hierarchy indexes one by one,which lays a foundation for the quantitative evaluation of the synthesis comfort of Beijing Subway.(2)The synthesis comfort evaluation model of Beijing Subway based on fuzzy comprehensive evaluation method is established.The calculated values or measred values of the lowest hierarchy indexes as the model’s input,using combined weighting method and combined with fuzzy analytic hierarchy process(FAHP)and rough set(RS)theory to determine the FAHP-RS optimization weight of each index in the model,using five-valued logical partition and semi-trapezoidal distribution establish the membership functions of each index,based on fuzzy synthesis operator model M(·,(?))optimization weight was synthesized with single factor evaluation matrix,finally based on the principles of the weighted average synthesis comfort score is obtained as the output of the model,and using this score to evaluate Beijing Subway synthesis comfort.Using the test data of the Line 1 on December 06,2018 and the Line 6 on December 19,2018 as examples,respectively uses this model to conduct the synthesis comfort evaluation,and made an in-depth analysis of the Line 1 data.The analysis results showed that the excessive noise is the main reason for the low synthesis comfort score of Line 1.(3)The evaluation system of comfort for Beijing Subway is designed and developed.In order to improve the application efficiency of the synthesis comfort evaluation model of Beijing Subway,the evaluation system of comfort for Beijing Subway is designed and developed.Based on the demand survey results of comfort management of Beijing Subway,according to the design objectives and principles of the system and analysis results of system functional requirements,the overall architecture,technical architecture and database structure of the system are designed in detail,and the system is developed in Microsoft Visual Studio 2017.Finally,combined with the system functions,the comfort evaluation result of Beijing Subway Line 1 is analyzed in detail to further verify the validity of the theory,method and model proposed in this paper.
