Development of High-Speed Railway Operations:from"Quantitative Change"to"Qualitative Leap"——An Evaluation Method Based on Frequency Statistics and Matter-Element Extension Model
Promoting the high-quality development of high-speed railways has become an inevitable requirement for realizing the national strategy of having strong transportation network.To evaluate the changes in the operational development of high-speed railways in China,this study supplemented the existing statistical indicators with a new indicator system.Firstly,frequency statistics and importance analysis methods were used to screen indicators.Subsequently,based on the dynamic evolution process of high-speed railway operations shifting from"quantitative change"to"qualitative leap",the paper constructed a matter-element extension comprehensive evaluation model on the basis of the Analytic Hierarchy Process(AHP).Through weight calculation and correlation analysis,decisive indicators were determined,and evaluations were conducted on eight subsystems of high-speed railway operational development.The results indicated that,the operational safety subsystem was at a"good"level but improving slowly.Innovative development,green development,basic support,and coordinated sharing were at a"suboptimal"level,with innovative and green development showing an upward trend,while coordinated sharing was facing the risk of decline.Openness development,transportation efficiency,and operational benefits were in a"moderate"state,trending towards"suboptimal"development.
