无人驾驶城轨车辆与信号系统接口的安全风险管理

Management of interface safety risk between driverless urban rail vehicle and signal system

为提升无人驾驶城轨项目的安全水平,结合无人驾驶技术标准及国内无人驾驶项目实践情况,对城轨车辆与信号系统开展接口梳理、危害识别、初始风险评估、风险减轻措施制定与分配以及剩余风险评估,借助HAZOP、FTA、事故走查法等安全分析工具,对城轨车辆与信号系统接口安全风险的识别和管控方法进行了探讨,得出一套可应用于无人驾驶城轨项目的接口安全风险管理方法。

In order to improve the safety of driveless urban rail project,combined with driverless technical standards and the practice of driverless urban rail projects in China,the interface analysis,the hazard identification,the initial as well as the rest safety risk identification,the development and allocation of risk mitigation measures of the vehicle and signal system interface are discussed.The safety analysis stools like HAZOP,FTA,accident inspection method,etc.Are used to investigate the interface safety risk management method which can also be used in other interfaces of driverless urban rail transits.
