Operational Risk Assessment Of Tianjin Rail Transit Security System

Rail transit system is a complex and densely populated transportation system.As an important carrier of urban population,rail transit system has the characteristics of strong space closure and special train location.Once terrorist attacks occur,it will have a great impact on personal life and social economy.Implementing safety inspection in rail transit stations,excluding inflammable and explosive,guns and ammunition,control knives and other items threatening operational safety outside the station doors,has become an inevitable measure to protect passengers’personal and property safety and maintain the stability of the operation of the subway system;ensuring that rail transit security inspection work is carried out strictly,efficiently and orderly,and giving full play to the role of security inspection as a barrier against terrorism,has become the whole.The inevitable requirement of national rail transit security inspection system.To ensure the safe operation of urban rail transit and give full play to the anti-terrorism and preventive role of security inspection system,it is necessary to adopt a scientific evaluation method and apply the theoretical principles of system engineering to sort out the potential risk factors of rail transit security inspection system from four aspects:system environmental factors,system personnel factors,equipment and facilities factors,and operation and management factors.By using the method of questionnaire survey,relevant research data are obtained,and the comprehensive evaluation method of fuzzy mathematics is used to establish an evaluation model for the behavior of rail transit security practitioners,so as to comprehensively evaluate the quality of security practitioners.At the same time,statistical analysis method is used to analyze the data to find out the key groups that affect the safety of rail transit security inspection system,and the correlation between them and the basic information of personnel.According to the conclusions of the study,some suggestions are made to improve the risk response ability of the rail transit security inspection system,to enhance the pertinence and effectiveness of the operation management of the urban rail transit system,to ensure the stability of the subway operation and to enhance the safety level,and to take into account the balance between the capacity of the subway and the speed of the security inspection,so as to form a security inspection solution under the large passenger flow.
