为了打造“一小时通勤圈”，建设“轨道上的城市群、都市圈”，形成“一票式”的互联互通新格局，建立城市间城市轨道交通自动售检票系统互联互通机制非常有必要。文章从标准、乘车凭证、计费及优惠方式、互联互通建设现状等角度对制约AFC系统互联互通发展的关键问题进行分析。从系统架构、标准编制、乘车凭证互联互通、票务管理互联互通等角度对AFC系统互联互通的建设提出了建议，为后续都市圈AFC系统票务运营一体化建设提供借鉴与参考。

In order to create "one hour commuter circle", build "urban agglomeration and metropolitan circle on the track", and form a new pattern of "one ticket" interconnection, it is very necessary to establish the interconnection mechanism of automatic fare collection system of urban rail transit between cities. This paper analyzes the key problems restricting the development of AFC system interconnection from the perspectives of standards, ticket vouchers, billing and preferential methods and the current situation of interconnection construction. This paper puts forward suggestions on the construction of AFC system interconnection from the perspectives of system architecture, standard preparation, Interconnection of ticket vouchers and ticketing management interconnection, so as to provide reference and reference for the subsequent integrated construction of ticketing operation of AFC system in metropolitan area.
