초록

한국은 교통안전도를 평가하기 위하여 228개 기초자치단체를 대상으로 교통안전지수를 산정하여 매년 발표하고 있다. 하지만 교통안전지수는 공간적으로 거시적인 관점에서 관련 자료를 취합하여 도출되기 때문에 개별 교통사고발생 지점의 현장상황의 파악 부재, 교통안전지수 산정기법의 정확성 및 신뢰성이 담보되지 않는 위험성, 그리고 해당 연도와 과거연도의 교통사고자료를 시계열적으로 연계하지 못하는 문제점이 존재한다. 본 연구에서는 메타분석을 이용하여 교통안전시설(도심형 중앙분리대)의 설치에 따른 시계열적 교통안전성을 부산광역시 구 군을 대상으로 거시적 관점에서 분석한 결과, 사하구, 북구, 동구, 부산진구를 제외한 모든 구 군에서 도심형 중앙분리대의 설치 후 교통사고 수가 증가한 것으로 확인되어 교통안전성의 거시적 분석의 개선에 대한 보완이 요구되는 것으로 나타났다.

Korean government annually estimates and reports the traffic safety index to evaluate the traffic safety of 228 Gu Gun. However, since the traffic safety index is derived from the spatially macroscopic perspective based on collected relative data, there are a couple of problems such as inability to investigate the individual traffic accidents on the spot, insecurity of accuracy and reliability of traffic safety index estimation method, and absence of establishing temporal relationship of traffic accidents. Thus, this study investigated temporal traffic safety in macroscopic manner for Gu Gun in Busan depending on the installation of the traffic safety facility (i.e., urban median), employing meta analysis. As a result, all Gu Gun in Busan except Saha, Buk, Dong, and Busanjin experienced more traffic accidents after installing the urban median, indicating that there are more rooms for improvement of macroscopic traffic safety evaluation.
