This paper aims to find out the statistical characteristics of the railroad accidents by weather phenomena. For this, It is investigated occurrence frequency of railroad accidents and operation obstacles from 1996 to 2008 in Korea using the KROIS data and Korea railroad accidents reports. The results are as follows; The occurrence frequency of railroad accidents and operation obstacles decrease gradually, and most of railroad accidents is a railroad traffic accidents. The amount of damages by a railroad weather-related accidents is higher than the one of the railroad accidents and operation obstacles. Weather events which is influenced the railroad weather-related accidents and incidents are rainfall, snowfall, lightning, strong winds. And they have occurred a railroad weather-related accidents and incidents, such as rail obstruction, signal failure, and power supply failure.

This paper aims to find out the statistical characteristics of the weather related railroad accidents and incidents. Data from Korea Railroad Operation Information System(KROIS) and Korea Railroad Accidents reports during 1996-2008 were used to investigate the occurrence frequency of railroad accidents and operation obstacles and their association with weather phenomena. The results are as follows; The occurrence frequency of railroad accidents and operation obstacles decrease gradually, and most of railroad accidents is a railroad traffic accidents. The amount of damages by a railroad weather-related accidents is higher than those of the railroad accidents and operation obstacles. It was also found that weather events influencing the railroad weather-related accidents and incidents are rainfall, snowfall, lightning, winds. And they caused a railroad weather-related accidents and incidents, such as railway obstruction, signal failure, and power supply failure. Therefore we need research about threshold review and a quantitative and qualitative analysis of a railroad weather-related accidents and incidents according to climate change.

In Korea, the number of railroad accidents is decreasing, but the scale of railroad accidents tend to be growing large. On considering the opening of the high speed railway in 2004, the problem of railroad safety is very important. The purpose of this study is to make plans for improving railroad safety of Korea. To make this plan, we generally analyzed the future railway traffic, and reviewed annual statistics of railroad accidents trend and case studies of foreign railway accidents.

본 연구는 기상현상에 의해 발생하는 노선별 철도기상사고의 통계적 특성을 밝혀 철도기상사고를 저감하고 향후 기후변화에 대비하고자 한다. 이를 위해 사용한 자료는 KROIS 자료와 철도사고분석보고서를 주로 이용하였으며 그 결과는 다음과 같다. 철도기상사고에 가장 취약한 노선은 경부선이며, 영동선과 중앙선, 태백선도 취약한 지역이라 할 수 있다. 철도기상사고의 종류는 선로장애, 신호장애, 급전장애 순으로 나타났으며, 선로 장애의 2차 원인은 노선별로 약간 차이는 있었으나 노반유실이 대부분이었고, 한랭전선을 동반한 기상패턴은 단시간의 집중호우로 철도기상사고를 일으키는 주요 기상패턴임을 알 수 있었다.

This paper aims to find out characteristics of railroad weather-related accidents and incidents and to proposes the plan of railroad disaster prevention according to the precipitation. For this, we make the database about the railroad weather-related accidents and incidents and analysis the relationship between the hourly and cumulative precipitation and railroad accidents. The results are as follows; The weather events that have the most occurrence frequency of railroad weather-related accidents and incidents is a rainfall of the precipitation and then the cause of that was the falling rocks and the collapsed roadbed. The rainfall patterns of collapsed roadbed were classified into 4 groups. When the variation of hourly rainfall is 10/15 mm/hr over, we need to consider the caution/stop of train operation and a speed limit, respectively.

Techniques related to railroad industry have progressed rapidly and the automation of work is prevailing. Since the railroad accidents due to the human error occupy considerable proportion among the railroad accidents, it is necessary to study the propriety of the physical examination system for the railroad workers. In this paper, we perform a comparative analysis of domestic and foreign physical examination systems for railroad workers. Through the comparative analysis, we suggest that test of the sleep-disorder be included in the physical examination.

철도시스템은 전세계적으로 가장 안전한 교통수단으로 인식되고 있지만, 사고는 계속 발생되고 있다. 많은 하위부분으로 구성되어 있는 철도시스템의 특성상 사고위험을 완전히 방지하기는 어렵다. 철도사고는 다양한 원인이 복합적으로 작용하여 하나의 사건으로 표출되기 때문에 사고의 근원적 예방을 위해 사고사례의 사고모드를 분석하고, 사고모드에 영향을 미치는 인자들의 상관관계를 역 추적하는 시스템적인 접근은 매우 중요하다. 본 연구에서는 미국, 영국, 캐나다, 오스트레일리아의 국외사고사례분석을 수행하며 주요 위험인자를 도출하였다.

Workers maintaining at the railroad trackside may collide with the train since they cannot recognize the train approaching because of the sensory block phenomenon occurred due to their long hours of continued monotonous maintenance work. To reduce these casualty accidents of maintenance workers working at the trackside of railroad, we developed the wireless communication-based safety equipment for preventing accidents. The motor-cars for maintaining trackside facility have unique operational patterns suitable for urban environment. The several mechanism for developed safety equipment are represented in this paper.

In January, 2005, the "Railroad Safety Act" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad safety issue, and each of the railroad operative institutions accepted such situation that the construction of the emergent system of coping, resulting in the construction of the emergent system of coping with the railroad fire accident through the relevant study to improve the railroad security efficiency against fire. This study tried to present the on developing the emergent educational program for coping with the KTX fire accident, which is distributed to the spot, to the railroad emergency staff for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedures against fire accidents the fire accident in KTX.

Korean railway has run about 110 years since 1989 and played a great role of industrialization in Korea. It is known that rail transport systems have many advantages of being more safe, energy-efficient, and environment-friendly, as compared to other transportation systems. However, railway incidents are often attributed to the failure of safety management and critical to the efficiency of railroad industry. This study reviewed economic, financial, and general statistical information on Korea Railroad. Based on the statistical data, the effect of accidents on railroad management was analyzed. Correlation analysis revealed that railway accident had a negative effect on the gross profit of Korea Railroad. In order to reduce potential risks and incident rate, some recommendations are proposed. Actual or potential applications of this research include safety guidelines for improving efficiency of railroad industry.
