Research On Standard System Of Metro Operation Safety

In recent years, with the speeding up of the urbanization in our country, the demand of the urban rail transit has gradually expanded. Meanwhile, people pay more and more attention to the development of the urban rail transit. Actually Metro has become the main way that people may choose to travel in urban area,providing a great convenience to the society. Especially in Beijing,Shanghai,Guangzhou,Shenzhen and other cities in China,the scale of metro operation has experienced from the multi-line operation to the network operation. And now it's expanded into more complex network operation, so how to manage the metro operation safety scientifically and standardizingly becomes an important topic.Metro system is huge and complex. At the same time, the process of metro operation involves the personnel,facilities,envirornment, management and so on, so the risk sources are complex. Besides, with the expansion of metro operation, the risk sources have become more and more complex. So that the management of metro operation safety faces a higher request. Therefore, this paper aims to put forward the metro operation safety standard system, to promote the standardization and development of metro operation. What's more?It provides more comprehensive guidance and support for the management of metro operation safety.First of all, this paper analyzes the present situation of China's metro operation,illustrates the importance of the management of the metro operation safety and introduces the standardization of the management method. On the basis of those above, i expound the necessity of implementing standard system.According to the research above,based on accident statistic research,this paper uses the system safety analytical method to summarize the main factors that influence the metro operation safety. This paper mainly analyzes from four aspects including human factors,equipment facilities, environmental factors and management factors. Thus to build a detailed three-dimensional structure and the proposed two-dimensional architecture of metro operation safety Standard System.The evaluation of metro operation safety is a big part in the management of metro operation safety. The establishment of the evaluation index depends on the metro operation safety Standard System. In this background, this paper will put forward the evaluation index system of metro operation safety. In order to manage metro operation safety from all sides,this paper establishes the evaluation index system of metro operation safety from the angle of stations, lines, and network.Finally, this paper puts forward the evaluation model of metro operation safety based on the theory of extenics. Take the metro in a city as an example to demonstrate the accuracy, validity and reliability of the model.
