Abstract

Since reports on trip delays or incidents often appear as accident articles on the press, the social criticisms and concerns on the safety of the urban railway are increasing. Therefore, a railway authority sometimes adopts an abstract safety goal like "let's build the urban railway to a masterpiece level" or "let's obtain an aeronautic safety level" to make citizens relieved and to alert involved persons. However with a vague goal, it is almost impossible to make an implementation plan systematic which helps the authority academically verify and validate if the goal is achieved or not. In this paper, the features of the railway safety are described and the safety models for securing the safety of the urban railway are surveyed and categorized. Based on the comparisons among the features and limitations of the models, we identify a more practical model which can be applied to the urban railway more effectively.

최근 언론에서는 운행지연 또는 소소한 사건을 사고 기사화 하여 도시철도 안전성에 대한 사회적 비판과 우려가 높아 지고 있다. 이에 따라 가끔 "명품 수준의 도시철도 건설" 또는 "항공 수준의 안전성 확보"등과 같이 추상적인 안전성 목표를 수립하여 시민을 안심시키고 관련 종사자의 경각심을 고취하고 있다. 그러나 이러한 모호한 안전성 목표는 그 달성 여부를 학문적으로 확인, 검증할 수 있는 체계적인 추진계획의 수립을 어렵게 한다. 본 논문에서는 도시철도 안전성의 특성을 살펴보고 도시철도 안전성 확보를 위해 적용 가능한 안전성 모델들의 유형을 조사, 분류하고 각 모델의 특성과 제한사항을 비교하여 국내 도시철도에 효과적으로 적용 가능한 모델을 확인한다.
