Railway Autonomous Safety Assurance System and Architecture
The paper constructs a Railway Autonomous Safety Assurance System(RASAS),which is capable of achieving holistic and ubiquitous perception,intelligent precision identification,predictive accurate analysis,proactive refined operation and maintenance,efficient emergency response,and performance testing and evaluation for all types of risk factors of"human-machine-environment-management"in the railway.The system's development goal is to transition towards a highly autonomous safety level with minimal or no human involvement,aiming at the overarching objective of zero fatalities due to accidents,zero major incidents,and zero system downtime.The system functional architecture is a five-tier structure constructed around train intrinsic safety,train operational environment safety,train operation safety,train fleet scheduling safety,and verification and validation.This architecture adheres to sixteen fundamental system principles,forming a systematic technological framework that includes both critical core technologies(such as risk perception,evaluation and warning,safety decision-making,and performance assessment)and foundational common technologies(like artificial intelligence and digital twinning).Moreover,this paper outlines a developmental path for the system ranging from experience-based responsive models to fully autonomous safety levels.The proposal and implementation of RASAS provide a strategic roadmap for the advances of railway safety assurance technology in China.The realization of this system further drives the global transportation industry towards increased intelligence and enhance safety.
