Infos

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.

Yong Qin is the Dr., Professor, vice dean of State Key laboratory of Rail Traffic Control and Safety, Beijing Jiaotong University. He also is the vice director of Beijing Research Center of Urban Traffic Information Intelligent Sensing and Service Technologies, the vice dean and secretary general of Rail Transportation Electro-technical Committee of China Electro-technical Society, the vice dean and secretary general of Rail Intelligent Transportation Systems Committee of China Intelligent Transportation Systems Society, and the member of IEEE ITS and RS, senior member of IET. He also has 'the China Outstanding Scientific and Technological Workers Award' and 'IBM Faculty Award'.

His research interests are in the area of intelligent transportation systems, railway operation safety and reliability, rail network management and traffic model. He has authored or coauthored more than 100 publication papers(SCI/EI), 1 ESI highly cited paper and 5 books, has 23 patents granted, also won 11 science and technology progress award of ministry, 2 Golden awards of international exhibition of inventions and so on.
