Abstract

Accident Black Spot Improvement Project is the representative road safety intervention to eliminate environmental risk factors on the roadway by installing road safety facilities. Although it is one of the main road safety projects in Korea, there has been a lack of effort analyzing the traffic accident reduction effects of this project. In this study, therefore, we selected 4,171 road black spots from 2004 to 2013 and investigated the traffic accident reduction effects of 5 road safety facilities by using "Comparison Group(C-G)" method. Through the analysis, it was found that the number of traffic accidents were lowered by 4.45% with traffic islands, 32.17% with road paved markers, and 24.13% with speed cameras, respectively. However, 0.61% with pedestrian fencing and 1.67% with skid resistant pavement were increased on the other hand. In addition, we also analyzed traffic accident reduction facilities' performance on specific types of collision mentioned in manual on road safety facilities by Ministry of Land, Infrastructure and Transport. It was shown that the number of bad weather traffic accidents were reduced by 52.96% with road paved markers, pedestrians accidents were reduced by 62.77% with pedestrian fencing and rear-end collisions were reduced by 26.00% with skid resistant pavement.

교통사고 잦은 곳 개선사업은 교통사고 예방을 위하여 도로상에 도로안전 관련 시설물을 설치함으로써 도로 환경적 요인에 대한 결함을 제거하는 대표적 교통안전개선사업이다. 그러나 개선사업으로 인해 설치된 각 시설물들에 대한 효과평가에 대한 연구는 미비하였다. 따라서 본 연구에서 도로 교통안전 관련 시설물의 교통사고 감소효과도를 추정하기 위하여 최근 2004년부터 2013년까지 교통사고 잦은 곳 개선사업 공사가 완료된 4,171개 지점을 대상으로 비교그룹방법을 활용하여 5가지 시설물에 대한 교통사고 감소효과도를 추정하였다. 분석 결과, 전체 교통사고에 대해서는 교통섬 4.45%, 표지병 32.17%, 과속단속카메라 24.13% 사고감소 효과를 나타냈으며, 반면 무단횡단금지시설 0.61%, 미끄럼방지포장은 1.67% 만큼 증가한 것으로 나타났다. 또한 표지병, 무단횡단금지시설, 미끄럼방지포장과 같이 국토교통부의 "도로안전시설 설치 및 관리지침"에서 특정유형의 교통사고 예방에 효과가 있다고 언급된 시설물들의 교통사고 감소효과도를 추가적으로 분석하였다. 그 결과, 표지병은 악천후 시 교통사고에 대해서 52.96%, 무단횡단금지시설은 차대보행자 교통사고에 대해서 62.77%, 미끄럼방지포장은 추돌사고에 대해서 26.60%의 순수 교통사고 감소효과가 있는 것으로 분석되었다.
