对现阶段行业内城市轨道交通云平台项目的现状进行介绍，阐述城轨云平台相关规范编制的成就，同时列举并解决城轨云平台的建设模式、城轨云平台算力纳管、城轨云平台的RAMS(reliability, availablity, maintainability, safety)指标建立、城轨云平台验收流程优化、城轨云运维体系建立等问题，并从城轨云平台自身技术驱动和规范编制两个方面，展望城轨云的发展方向。

This study presents the cloud platform status quo in the urban rail transit industry at the present stage, and expounds the achievements of compiling related specifications of urban rail cloud platforms. Furthermore, it lists and solves the construction mode optimization of the urban rail cloud platform. The urban rail cloud platform should include a mixed computing capacity, the establishment of an RAMS index, the acceptance optimization, and the establishment of the urban rail cloud operation and maintenance system. The development direction of the urban rail cloud is prospected from two points of view: the technical drive, and compilation of specifications.
