Abstract

The purpose of this study was two-fold; first, to develop safety performance functions (SPF) using transportation-related big data for all types of roads in Korea were developed, Second, to provide basic information to develop measures for relatively dangerous roads by evaluating the safety grade for various roads based on it. The coordinates of traffic accident data are used to match roads across the country based on the national standard node and link system. As independent variables, this study effort uses link length, the number of traffic volume data from ViewT established by the Korea Transport Research Institute, and the number of dangerous driving behaviors based on the digital tachograph system installed on commercial vehicles. Based on the methodology and result of analysis used in this study, it is expected that the transportation safety improvement projects can be properly selected, and the effects can be clearly monitored and quantified.

본 연구는 우리나라 전체 도로 유형을 대상으로 빅데이터를 이용하여 안전성능함수(safety performance function, SPF)를 개발하고, 그것을 바탕으로 다양한 도로에 대한 안전등급을 평가함으로써 상대적으로 위험한 도로에 대한 대책을 수립할 수 있는 기초 정보를 제공하고자 하였다. 교통사고 자료를 국가표준 노드 및 링크 체계를 기반으로 전국의 도로에 매칭 하여 종속 변수로 활용하였으며, 독립변수로 링크 길이, 차로 수 등 기하구조 자료 및 한국교통연구원의 ViewT 교통량 자료, 그리고 사업용 차량에 장착된 운행기록계를 통한 위험운전행동 건수를 활용한 4개 시스템의 교통 빅데이터를 활용하여 연구를 진행하여 7개 도로 유형별 안전성능함수를 개발하고, 개발된 안전성능함수를 활용하여 도로유형별로 A, B, C, D 네 개의 안전등급을 평가하였다. 본 연구에서 사용한 방법론과 분석 결과를 토대로 우리나라의 위험도로를 선정하였다. 도출된 결과를 바탕으로 교통안전 개선사업의 대상을 선정하고 그에 따른 효과 등을 모니터링하고 계량화할 수 있을 것으로 기대된다.
