Study On Safety Operation Evaluation Of Metro Vehicles

Along with the rapid development of Urban Rail Transit,rail transit in mega cities has entered a new era of networking operation with the constant expansion of road network and the steady growth of passenger flow.Metro is the core part of Urban Rail Transit and the importance of its safety operation placed on people‘s lives comes to prominence.Vehicle system,as one of the most complicated systems,covers plenty of fields.Studying on its safety checklist analysis plays a significant role.This thesis will form a set of theoretical method pertaining to metro operation safety operation.Then,it will analyze and appraise safety operation state of metros open to traffic.It will be divided in:(1)An analysis of metro safety operation features.By thorough analyzing the characteristic of operation and accident,this thesis will search for the regularity of distribution,the possibility of occurrence and interaction relation of risk factors.(2)A statistical analysis of metro vehicle accident at home and abroad.Through collecting data and analyzing the metro accident at home and abroad,I will summarize main types of accident and its influence factors.(3)An analysis of influence factors involved in vehicle safety operation.This thesis will make a profound analysis from four perspectives and dig deep relations among factors affecting safety operation.(4)The establishment of vehicle operation safety evaluation system.This thesis will set up a model of vehicle operation safety evaluation system after screening evaluation index,forming evaluation criteria and choosing evaluation method.(5)Cases analysis.Through analyzing cases,the applicability and scientificity of the evaluation model will be verified.Besides,this thesis will draw a conclusion in the process of research that there is much to be improved to guide late research work.This thesis takes Line X of X Railway Operation Company in China as an example and verifies the applicability and scientificity of the above methods.It turns out that metro vehicle system,as the core system of metro operation system,is of vital importance in safety operation.Safety and reliability of equipment itself matters the most in safety operation.Extreme weather conditions also have a significant impact.In the end,this thesis concludes that taking how much time affecting main lines operation as a criterion to evaluate metro safety operation state is scientific and viable.
