Research on Risk Control Scheme of Casualties Based on Man-made Events in Rail Transit
In order to study the control scheme of casualties in urban rail transit,a method to determine the control scheme was proposed based on the relationship between man-made events and casualties.Firstly,the man-made event risk in rail transit is described.The evolution of human casualties is studied.The method of determining the measure scheme to control the event and the evolution condition is developed.The research shows that the man-made events in urban rail transit constitute a major safety hazard,reduce operation efficiency and cause economic losses;the evo-lution relationship between man-made events and casualties is complex,so it is the key to make risk control scheme to ensure the safety.Based on the space fault network,the evolution network diagram of human casualties is con-structed,focusing on the events and evolution conditions,and the control scheme is formulated by dissolving the path and calculating the utility ratio.The method of determining the control scheme according to the event and evolution conditions are proposed,the analysis system is constructed,the relevant factors are defined,the utility ratio is calcu-lated and sorted,and the optimal measure scheme is formed.An example is given to verify the effectiveness of the method,a casualty risk control scheme is formed,and the advantages,disadvantages and usability of the algorithm are discussed.
