摘　　要：由于全自动运行地铁无司机驾驶,随之而来的是一系列安全和运营保障问题;同时,既有线系统的RAMS(可靠性、可用性、可维护性和安全性)指标,也无法全面指导全自动运行RAMS体系的建设。从既有线故障情况、驾驶模式、运营场景三方面,对全自动运行对信号系统RAMS指标的影响进行讨论。The driverless fully automatic operation is followed by a series of safety and operational security issues,meanwhile,the existing line system RAMS(reliability,availability,maintainability,and safety)index can not comprehensively guide the construction of RAMS system for fully automatic operation system.From aspects of existing line failure,driving mode and operation scene,the impact of fully automatic operation on the signal system RAMS index is discussed.
