Abstract
Based on the train positioning principles,and the calculation principles of train authorization profile,this paper mainly analyzes the generation mechanism and extension mechanism of buffer zone for train safety protection.By establishing different operation scenarios,this research studies how the extension of buffer zone exerts influences on subsequent CBTC-based train operations in the event of loss of location information of the preceding train or fault of the onboard ATP equipment.The research findings indicate that the extension of buffer zone leads to the restriction of movement authority or even the triggering of emergency braking of the subsequent trains,and thereby results in the reduction of carrying capacity of the rail line.On this basis,this paper provides corresponding countermeasures such as adding axle counting points and optimizing train headway,which can provide reference for train operation organization and efficiency improvement in fault conditions during actual operation services.关键词
