  • 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.

  • 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 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.

  • 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.
