철도시스템에 ALARP모델 적용을 위한 연구

초록

In this paper we develop the model for applying ALARP(As Low As Reasonably Practicable) into train system. We develop the quantitative judgment model considering cost-benefit before and after applying safety measures with the application of ALARP theory to safety facilities whose need for installation is reviewed by past experience, the relevant legislation, etc. We also apply the developed model to safety system, established for the purpose of maintenance staffs and citizens to train collision at vulnerable locations on railway and protecting train accidents caused by terrorism or sabotage, and review feasibility. With the ALARP application model presented in this paper the need for safety equipment to ensure the railway safety. We present the model to allow for the quantitative review by cost analysis
