Abstract

Trucks take up more portions than cars on highways. Due to this, road use relatively diminish and it serves locally as a threatening factor to nearby drivers. Baggage car accident has distinct characteristics so that it needs the application of different analysis opposed to ordinary accidents. Accident prediction model, one of accident analyses, is used to predict the numbers of accident in certain parts, establish traffic plans as well as accident prevention methods, and diagnose the danger of roads. Thus, this study aims to apply the accident rate of baggage car on highways and calculate the correction factor to be put in the accident prediction models. Accident data based on highway was collected and traffic amounts and accident documents between 2014 and 2016 were utilized. The author developed an accident prediction model based on numbers of annual accidents and set mean annual and daily traffic amounts. This study intends to identify the practical accident prediction model on highway and present an appropriate solution by comparing the prediction model in accords with the accident rate between baggage cars.

고속도로에서 화물차는 승용차에 비해 도로의 많은 부분을 점유한다. 이로 인해 도로의 용량은 상대적으로 감소하며, 국소적으로 주변 운전자에게 위협적인 요소로 작용한다. 화물차 사고는 일반적인 사고와 달리 사고 특성이 다르므로 분석 방법 또한 일반적인 사고와 다르게 적용해야 한다. 사고 분석 방법 중 사고예측모형은 특정 구간에 대한 사고건수를 예측하며 교통계획을 수립할 때 사고 예방을 위한 대책 수립과 도로의 위험성을 진단할 때 활용된다. 이에 본 연구는 고속도로의 화물차 간 사고 비율을 적용하여 사고예측모형에 투입될 수 있는 보정계수를 산출하는 것을 목적으로 한다. 연구를 위해 고속도로를 대상으로 사고 자료를 수집하였으며 2014~2016년까지 3개 년도의 교통량 및 사고 자료를 활용하였다. 연간 사고건수를 토대로 사고예측모형을 개발하였으며, 본 연구를 통해 화물차 간 사고 비율에 따른 사고예측모형을 비교함으로써 실질적인 고속도로 사고예측모형을 확인하고 그에 대한 대책을 제시하고자 한다.
