Abstract

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.

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.
