However, the new safety accidents such as the passenger injured, the rapid stop of train and the pass after non-open PSD due to the failure or malfunction, the handling errors of PSD occurred and the frequency of these accidents has been gradually increased. This study investigates the problems of PSD of the R/F (Radio Frequency) method and the detection sensor method which are installed in Seoulmetro and analyzes the causes by arranging the PSD accidents types and then presents the solution to the generalized. As a result, this study derives the safety requirements of PSD and suggests the safety operating agenda.
