Flexible marshalling,as a brand-new technology for flexible organization and operation of urban rail transit,aims to solve the problems of high-density operation of large groups of passengers at peak hours and high-density operation of small groups at flat peaks under the same train interval of the same line equipped with different capacity at different time and areas.The flexible marshalling technical scheme can cope with the passenger flow risk,relieve the peak transportation pressure,improve the operation efficiency and service level of the flat peak,and save the operation energy consumption and operation cost.The key technology of flexible marshalling is coupling/uncoupling technology.From the perspective of rail transit operation requirements and the capability characteristics of fully automatic operation system,this paper analyzed the core specialties such as driving ability,vehicle interface,civil engineering reservation conditions,platform door layout,and signal system and designed a safe and feasible coupling/uncoupling technical scheme,which solved the main difficulties in flexible organization and operation of urban rail transit and provided detailed and feasible design case reference for building safe and economical rail transit and promoting the development of energy-saving green rail transit.
