The improvement project for school zone in Korea is occurring mostly in kindergartens and elementary schools in which children are mainly active, and is being promoted as part of measures to prevent children's traffic accidents. However, since the study on the essential installation facilities and proper level of safety facilities for School zone is lacking, this study relatively evaluated the efficiency of safety facility installation using DEA (Data Envelope Analysis) and suggested improvement plan. We built the facilities and incident data for 28 school zones in Hwaseong City. Six major facilities (Raised intersection, Raised crosswalk, Protective fence, Skid Proof, Speed hump, Speed cameras) that have proven to be effective in the preceding research were analyzed as input factors. As a result of the analysis, only 12 out of 28 showed efficiency and 16 out of efficiency. Effective groups of school zones were found to have fewer installed Protective fences, Skid Proof, and Speed cameras installations than school zones classified as ineffective groups. Protective fences were found to be efficient even if only 47% of the total extension of the school zone was installed, and the number of slip prevention facilities was 8.7 per square km. The number of subjects to be compared is 28, so this study is limited to use as a relative efficiency evaluation index, and it can be grouped into nationwide units and efficiency evaluation can be done for each group.
우리나라의 어린이보호구역 개선사업은 어린이가 주로 활동하는 유치원, 초등학교 주변에서 많이 발생하고 있어 어린이 교통사고 예방책의 일환으로 추진하고 있다. 하지만 어린이보호구역내 안전시설물에 대한 필수 설치 시설물과 적정 설치 수준에 대한 연구가 부족한 바, 본 연구에서는 자료포락분석을 활용한 안전시설물 설치의 효율성을 상대적으로 평가하여 개선방안을 제시하였다. 화성시 관내 초등학교중 총 28개 어린이보호구역에 대한 시설물 현황과 사고현황 자료를 구축하였다. 기존 연구상에 효과가 입증된 주요 시설물 6개(고원식 교차로, 고원식 횡단보도, 방호울타리, 미끄럼방지시설, 과속방지턱, 단속카메라)만 투입요소로 하여 분석하였다. 분석결과 28개소 중 12개소만 효율성이 있는 것으로 나타났으며, 16개소는 효율성이 떨어지는 것으로 나타났다. 효율집단으로 구분된 어린이보호구역은 방호울타리, 미끄럼방지시설, 단속카메라 설치가 비효율집단으로 구분된 어린이보호구역보다 적게 설치한 것으로 나타났다. 방호울타리는 어린이보호구역 전체연장 중 47% 정도만 설치하여도 충분히 효율성이 있는 것으로 나타났으며, 미끄럼방지시설의 개소 수는 ㎢당 8.7개 정도면 효율성이 있는 것으로 나타났다. 비교대상의 수가 28개소로 상대적 효율성 평가지표로 활용하는 데는 본 연구가 한계가 있으며, 향후 전국단위로 그룹화 하여 각 그룹별로 효율성 평가할 수 있을 것으로 판단된다.
