철도교통사고(railroad traffic accidents)는 열차 또는 차량의 운전에 의해 발생되는 열차사고(train accident), 건널목사고(level-crossing accident), 교통사상사고(traffic death and injury)로 구분되며 장기간 지속적 감소추세를 보이고 있다. 철도산업정보센터의 철도사고 통계자료를 활용하여 열차사고와 건널목사고의 발생빈도를 비교해보면 1990 년대 90%이상, 2000 년대 80%이상 건널목 사고빈도의 점유율이 높은 것을 알 수 있다. 본 연구에서는 건널목사고의 시계열적 특성을 살펴보고 단기예측 및 계절적 특성에 대해 살펴보았다. 분석자료는 과거 20 년간 집계된 건널목 사고빈도자료를 이용하여 월별발생 빈도와 계절적 빈도자료로 활용하였다. 분석결과 사고빈도는 계절형발생 특성을 보이며, 단기적 큰 감소추세를 보이지 않는 것으로 나타났다.
Railroad traffic accident consists of train accident, level-crossing accident, traffic death and injury accident caused by train or vehicle, and it is showing a continuous downward trend over a long period of time. As a result of the frequency comparison of train accidents and level-crossing accidents using the railway accident statistics data of Railway Industry Information Center, the share of train accident is over 90% in the 1990s and 80% in the 2000s more than the one of level-crossing accidents. In this study, we investigated time series characteristic and short-term prediction of railroad crossing, as well as seasonal characteristic. The analysis data has been accumulated over the past 20 years by using the frequency data of level-crossing accident, and was used as a frequency data per month and year. As a result of the analysis, the frequency of accident has the characteristics of the seasonal occurrence, and it doesn’t show the significant decreasing trend in a short-term.
