Abstract

Roadside non-point pollution reduction facilities are classified as infiltration, vegetation, reservoir, and wetland types based on their respective pollution reduction mechanisms. However, without a detailed analysis of the road and traffic conditions it is very difficult for civil engineers to determine which category of pollution reduction facility is best suited to their planning requirements. To address this issue, we propose a new decision-making method for the selection of roadside non-point pollution reduction facilities. The principal factors informing the proposed decision-making methods are the road characteristics, including location, structure, number of lanes, and traffic volume. As a result of the study, a total of new pollution reduction plans were developed, with their selection conditions and the corresponding applicable facilities established. The effectiveness of the proposed pollution reduction schemes was demonstrated for roads in Kyounggi-do, providing a valuable basis for future pollution reduction plans.

국내의 도로비점오염저감시설은 오염원을 저감시키는 성능에 근거해서 침투형, 식생형, 저류형, 인공습지 등과 같이 분류된다. 이 분류기법은 기법을 이해하기는 용이하나 도로교통과 관련된 요소가 고려되지 않아 실제 도로기술자가 계획이나 설계에 적용할 때 애로가 많았다. 본 연구에서는 도로비점오염저감시설을 설계에 적용할 때 시설의 종류를 결정할 수 있는 분류방법론을 개발하였다. 도로의 특성 (위치, 차선, 교통량), 시설여유, 도로의 구조물 등을 주요 결정인자로 도로비점저감 대책의 의사결정과정을 만들어 유형별로 시설을 선정할 수 있는 기법을 개발하였다. 각 유형별로 사이트의 조건과 적용이 가능한 시설 및 대책을 정리하여 현장에 적용할 수 있도록 하였다. 개발한 기법은 경기도 도로구역에 적용하여 보완하였고, 비점저감 계획에 사용할 수 있도록 하였다.
