Research on the Integrated Modes of Rail Transit Dispatching Command for Metropolitan Area

［Objective］ Researches on the integrated dispatching and command modes for metropolitan area rail transit conduce to address problems in operational management coordination and linkage among different levels of rail transit systems, enhancing the transportation organization efficiency and service quality. ［Method］ By analyzing the connotation and requirements of rail transit dispatching and command integration, as well as the current development status of metropolitan area rail transit dispatching and command around the world, three dispatching and command modes suitable for the background of metropolitan rail transit integration are proposed on this basis: trusteeship mode, centralized office mode, and unified management mode. Using the TOPSIS(technique for order preference by similarity to an ideal solution) evaluation method, the above-mentioned modes are assessed from three dimensions: service quality, implementation difficulty, and overall effectiveness. Corresponding management rules for dispatching and command integration are formulated to provide decision-making guidelines for operating enterprises. ［Result & Conclusion］ The trusteeship mode and unified management mode are more suitable for the rail transit co-line operation environment, and conducive to ensuring the train operation safety and improving the operation management efficiency. It is recommended that operating enterprises should choose a reasonable integrated dispatching and command mode after considering the line scale and demand comprehensively.
