Systems Science and Traffic Security

The safe operation of traffic and transportation is always a core and basic work.The 27th conference of "Traffic and Transportation Forum 7+1" focuses on the issue of "systems science and traffic security".Some basic theories and frameworks on systematic safety are introduced.The existing security problems are analyzed for several systems such as high-speed railway,urban rail transit,air transportation,and road traffic.The essential elements of safety engineering are explored in terms of the procedure,framework,standard and research method.Based on the domestic and international cases and practices,the strategic goals,achieving methods and the key techniques are put forth for traffic security system.In addition,some items on the "12th Five-Year Plan" of high-speed railway are discussed and the consensus are proposed as that building and improving the national safety standards and practical strategies should be the keys for future development.
