Safe and high-efficiency operation are two main issues in rail transportation. This book
focuses on these two key issues bringing together a wealth of research to offer theoretical
and technical support for rail operations and maintenance. In addition it presents a
comprehensive active safety assurance system for rail transportation which includes the
quantitative state identification and prediction of train components rail transportation
safety and reliability assessment methods and rail transportation risk assessment at the rail
networks level which achieves the quantitative and high-precision monitoring of complex
systems in real-time. In addition it extends active safety based theory to safety prognostic
analysis in the traffic system. Lastly representative case studies verify that the theory is
suitable for the actual traffic system.
