Abstract: This paper proposes a scenario-based safety analysis method for fully automatic train operation systems. All the operation scenarios of fully automatic train operation systems are modeled, and the influencing factors in each scenario are identified, to quickly identify the possible operational risks and avoidance measures in each operation scenario of fully automatic operation systems. The effectiveness assessment of such measures is made on the basis of the residual risks. Thus, a series of protection measures through human intervention are obtained for various operating scenarios of fully automatic systems, which solves the problem that the systems provided by multiple suppliers cannot be analyzed as a whole, and improves the operation safety of fully automatic systems.

Key words: fully automatic train operation system, safety analysis method, scenario-based safety analysis
