Research On Coordination Analysis And Evaluation Of Urban Rail Transit Line Operation Based On Simulation

With the network scale increasing, urban rail transit is gradually moving in network operation mode. Enhancing the rail network operation coordination is the key for increasing rail network operation efficiency, which needs a set of network operation coordination analysis and evaluation method.In this paper, aimed at different aspects of operational coordination problems in the process of lines operation, the methods based on computer simulation technique have been studied to analyze and evaluate urban rail transit lines operational coordination, which could provide decision-making basis for lines operational coordination. The main researches as follow:1) In terms of the research scope, time scale, issue boundary and research levels, the composition of urban rail transit operations coordination was analyzed; for the operational organization of the lines, the impact elements of coordination, coordination means and methodological basis were studied; for analyzing and evaluating the lines operational coordination, and for the purpose of optimizing "integration", the idea of assistive technology for lines operational coordination based on computer simulation was proposed;2) For the common needs of analyzing and evaluating lines operational coordination, there was an analysis of the characteristics of the coordination index system. After summarizing the different themes of analyzing and evaluating lines operational coordination, the lines operational coordination issue was divided into two sub-issues. Respectively, for two sub-issues, there was a coordination index set consisting of impact elements subset and effects subset. The index refining methods based on data clustering were studied, by using instance data of Beijing subway, the index sets were refined to the lines operational coordination index system, which would provide quantitative criteria with consistency for coordinate analysis, evaluation and further optimization.3) The quantitative effect relationship between coordination impact elements and operational effects has been studied, by the use of data analysis tools, and a recognition method for the key impact element of lines operational coordination was proposed. For the "zones" coordination sub-issue, the level of the key element was identified through a balanced index, and for the transfer stations coordination sub-issue, the specific key element index was identified through the method of sensitivity analysis SEM-based, and there were examples of identifying key elements of lines operational coordination. Furthermore, with data envelopment method, the transfer stations coordination sub-issue was evaluated.4) Based on the simulation platform of urban rail transit road network, this paper designs the line operation coordination analysis and evaluation system; As Beijing rail transit for example, this paper studies the coordination analysis and evaluation of the transfer station.
