Research On Operation Safety Management Of Metro Station Based On System Dynamics

In recent years,urban rail transit has played an increasingly important role in leading and supporting urban development,promoting social and economic development,optimizing urban layout structure,reducing environmental pollution,improving traffic congestion,and increasing public travel.However,at the same time,the safety hazards of urban rail transit operations have become increasingly prominent,and safety accidents have frequently occurred,which seriously threatened people's lives and property safety and affected the sound development of China's rail transit industry.Based on this,this article first reviews the current status of subway operation at home and abroad from the development history,research objects,research methods,research content,and empirical analysis.Secondly,it deeply analyzes 223 subway operation safety accidents in China from 2000 to2019,explores the causes of various accidents,reveals the causes of accidents,finds out the rules between accidents,and obtains the influence of subway stations through case analysis Various factors and probability values of operational safety.Thirdly,A dynamic model(System Dynamics,SD for short)of the subway station operation safety management system was constructed,a model equation was established,and a comprehensive integration weighting theory was introduced to determine the model system index weight value,and the CEC relationship of subway station operation safety management was revealed(Causality and stock flow diagram),the interaction relationship between each system and its key impact factors,and stock flow relationship are obtained.At last,Based on the system model simulation,the safety level of subway station operation safety management in China during the past five years is simulated and predicted.The results show that the operational safety status value of the subway station conforms to the actual objective law and expected effect of the station,and the simulation results combined with 5G,AI and other new technologies have proposed specific improvements for the actual operation of the subway station operation safety management,which can effectively improve Safety and reliability of subway station operation.
