Analysis of Safe Operation Behavior for Dispatching Fully Automated Operation Urban Rail Transit Lines Based on FTA

One of the main differences between fully automatic operation lines and traditional lines is job composition. The flat operation management system formed after job recombination can achieve the goal of reducing staff and increasing efficiency and reducing labor costs for operating units. In this way, more functions are integrated into the center, and the impact of central dispatchers on on-site operations will be more direct. In this situation, higher requirements are placed on the emergency response capabilities and operational skills of the dispatch personnel. This article uses the Fault Tree Analysis (FTA) method to conduct a risk analysis on the safety operation behavior of urban rail transit fully automatic operation line dispatch command, analyzes the weak links in the production operation process of dispatch command, establishes a fault tree, and describes the top event, intermediate event, and basic event of dispatch command safety operation behavior. The minimum path set, and structural importance parameters of the accident tree were analyzed and calculated, and an equivalent tree of the accident tree was drawn. Three of the minimum path sets were selected for analysis, and effective measures to prevent improper scheduling and command were proposed.
