Operational Risk Assessment Method Based on Wayside and Vehicle Condition Information for Autonomous Train Operation

Abstract

We are developing an autonomous train operation system that allows trains to operate automatically while controlling wayside equipment based on the condition of the vehicle and wayside equipment. Autonomous train operation not only controls the acceleration and deceleration of trains, achieved through automatic operation, but also automatically makes operational decisions on board. We have developed the railway dynamic map as an information infrastructure for collecting and sharing onboard and wayside condition information needed for operational decision making and for risk assessment. This paper provides an overview of condition information management and risk assessment using the railway dynamic map.
