고속철도 운행, 도시철도 고밀도화, 무인자동운전의 경량전철 등 신교통시스템 도입 등 급변하는 철도환경에 따른 철도안전의 위험요인이 증가하고 있다. 국내 철도사고 사망자는 설비개량, 노후차량교체, 건널목입체화로 감소하고 있으나 10년을 주기로 대형참사가 발생하고 있으며, 철도관련 종사자의 안전의식이 낮은 수준이다. 이러한 대형참사의 발생을 방지하기 위하여 철도안전법이 제정되고 이의 효율적인 시행기반을 구축하기 위하여 철도시설안전체계 구축 및 기술분야별 안전기준을 개발하고 있다. 본 논문에서는 철도종합기술개발사업의 철도사고 위험요인분석(PHA : Preliminary Hazard Analysis)을 토대로 관계있는 위험원을 선정하였다. 또한 위험원에 의한 사고발생을 예방하기 위한 철도신호분야의 안전기준항목을 기술하였다.

As a result of investment in railway safety focusing on passenger safety, the train accident rate has been reduced by half domestically and we have reached a high level of safety compared to other countries and other transportation modes. However, accidents related to staff are still at a high ratio compared to other countries. There have been few studies on staff safety and no relevant systematic safety measures have been implemented. More than 90% of staff fatalities occurred from rolling stock in motion and electrification, which are representative railway accidents. In this study, causes of accidents, and current safety measures for staff are analyzed focusing on trains in motion. The results can be utilized for developing new safety measures.

Safety is an essential requirement for public transportation, especially for railway. Railway are more safety than other means of transportation, but railway accident that is mass transportation result catastrophic result if an accident occurred. Railway operators and government are many prior efforts to prevent accident, but it is impossible to eliminate accidents. Therefore, various measures to reduce accidents as possible, and they have taken, this paper will review incident report system and safety culture which are most important factors for preventing accident. In addition, incident reporting system and an independent accident investigation and accident prevention and safety systems would be needed to improve train operating companies and related agencies for the safety of the railway is a cultural ritual. Indeed, the settlement of avalid railway safety culture will most certainly prevent railway accidents. Therefore, in the railway company and the correct understanding of railway safety culture and against the settlement plan would be reviewed in this paper.

철도는 대규모 수송수단으로 국가 교통의 중추적인 역할을 담당하며 천재지변이나 인위적인 요인에 의해 발생되는 열차사고는 대규모 인명피해와 경제적인 손실을 초래하기 때문에 사고의 예방, 초기 대응과 더불어 신속한 사고복구는 중요하다(중략)

Rail human factors research has grown rapidly in both quantity and quality of output over the past few years. Human factors, also, still plays a significant part in many railway accidents. In this paper we review categorized performance shaping factors of human errors associated with railway accidents within and out of the country. This paper deals with the selection of the important performance shaping factors under accident management situations in railway for use in the assessment of human errors. The purpose of this study is to classify which human error would be selected for accident analysis. Therefore, the classification of human errors suggested in this study may be useful to enhance the Korean railway system safety.

1899년 공중의 운송수단으로 철도가 우리 생활속에 자리잡은지 100년이 지났으며, 현재는 시속 300km에 육박하는 고속철도가 준공되고 있는 실정이다. 그러나 철도기술이 발전됨에 따라 안전사고도 증가하여 많은 인명상, 재산상의 피해를 초래하고 있다. 2000년 의 철도사고는 572여건에 225명이 사망하고 347명이 부상을 입었다. 이러한 수치는 1998년을 기점으로 점차로 줄어들고 있는 추세이나 아직까지도 재해의 원인을 살펴볼 때 안전수칙 미준수나 기계기구의 취급부주의와 같은 후진국 수준의 원인이 큰 비중을 차지하고 있는 실정이다. 모든 산업사고는 재해조사표에 근거하여 재해를 분석하고 있으며, 이의 결과는 동종재해 및 유사재해의 재발방지 수립대책으로 활용되어야 한다. 따라서 본 연구에서는 산업재해조사표를 기준으로 FTA분석을 실시하여 철도사고에 대한 보다 객관적이고 체계적인 원인을 규명하고자 하였다.

우리는 복잡한 현상을 하나의 수치로 표현하는 각종 지표(index)를 생활에서 많이 접하고 있다. 종합주가 지수, 불쾌지수, 소비자 물가지수, 년간 교통사고 건수, 인구 10만명당 교통사고 사망자수 등도 일종의 지표라 할 수 있다. 철도에서도 위험을 평가하는 지표로는 "년간 사고건수", "열차운행 100만-km당 사고건수"와 같이 발생빈도에 초점을 둔 경우와 "년간 사망자수", 혹은 "피해액", "운행지장"과 같이 사고피해에 초점을 둔 경우가 있다. (중략)

This paper aims to find out the statistical characteristics of railroad weather-related accidents and incidents of each railroad line and then reduce the railroad accidents and prepare for the climate change. For this, we used data of KROIS and Korea railroad accidents report during 1996-2008. The results are as follows; Gyeongbu line is the most vulnerable line to railroad weather-related accidents, Yeongdong and Taebaek line are also the vulnerable line. The main railroad weather-related accidents and incidents is a railway obstruction and the next is a signal failure, a power supply failure. The second cause of a railway obstruction was some different for each line, but the main cause was a collapsed roadbed. We knew that the cold front accompanied with a heavy rainfall for a short time is the main weather pattern which cause the railroad accidents.

Negligent accidents in urban railway station not only give damages to users but also cause avoidance of public transport usage. This study aims to identify design factors in designing urban railway station for reducing and preventing negligent accidents in the station. Especially this study identifies design factors from the perspectives of universal design concept which is for all persons. This study classified negligent accidents in urban railway stations, analysed degree of danger and identified the causes of accidents. Then this study identified universal design factors based on the results of analysis on the priority of accident factors relating to negligent accidents. The results of this study can be utilized as basic data in designing urban railway station for reducing and preventing negligent accident in urban railway station.

This study is a railway accident investigation statistic study with the purpose of prediction and classification of accident severity. Linear regression models have some difficulties in classifying accident severity, but a logistic regression model can be used to overcome the weaknesses of linear regression models. The logistic regression model is applied to escalator (E/S) accidents in all stations on 5~8 lines of the Seoul Metro, using data mining techniques such as logistic regression analysis. The forecasting variables of E/S accidents in urban railway stations are considered, such as passenger age, drinking, overall situation, behavior, and handrail grip. In the overall accuracy analysis, the logistic regression accuracy is explained 76.7%. According to the results of this analysis, it has been confirmed that the accuracy and the level of significance of the logistic regression analysis make it a useful data mining technique to establish an accident severity prediction model for urban railway casualty accidents.
