머 리 말

우리나라의 도로는 1970년 경부고속도로 건설을 시발로 현재 약 3,400km의 고속도로망을

포함한 104,000km나 되는 양적·질적 팽창을 이루었으며, 여객·화물 수송의 약 95%를 담당

하는 국가 중추 교통시설이 되었습니다.

이러한 도로망을 체계적으로 확충하기 위하여 정부에서는 도로의 계획·설계 및 유지업무의

기준이 되는「도로구조령」을 1965년도에 대통령령(제2177호)으로 처음 제정한 후, 1990년

도에는 차량의 대형화·고속화 추세에 맞추어「도로의 구조·시설기준에 관한 규정」으로 명칭

을 바꾸어 대폭 개정한 바 있습니다.

그 후, 새로운 첨단기술의 도입과 급변하는 21세기 기술적 변화에 보다 신속히 대응할 필요

성이 대두됨에 따라, 1999. 8. 9 동 규정을「도로의 구조 ․ 시설기준에 관한 규칙」으로 변경

하여 건설교통부령(현 국토해양부)으로 전환하였습니다.

그러나 1999년도 이후 도로에 대한 각종 설계기준과 지침들이 보완 ․ 개정되면서, 상기 규칙

과 상이한 부분에 대한 일치된 기준정립이 필요하게 되었습니다. 또한 최근 도심 교통혼잡 구

간의 교통정체와 도로 정비가 필요한 구간에서 용지 제약의 문제점을 해결할 수 있는 소형차

도로의 기준과 교통약자를 배려한 도로시설 기준 등이 필요함에 따라 2009년 2월「도로의 구

조·시설 기준에 관한 규칙」을 개정하게 되었습니다.

본 해설서는 금번 개정된「도로의 구조·시설 기준에 관한 규칙」에 맞추어 규칙의 내용 해

설과 더불어 체계적이면서도 기본적 이론을 구체적으로 제시하였으며, 도로 설계 및 계획에 참

여하는 초급기술자들도 쉽게 이해하고 실무에 적용할 수 있도록 하였습니다.

끝으로, 본 해설서를 활용하시는 여러분의 많은 조언이 있기를 바라며, 본서의 발간을 위해

정성을 다해 주신 대한토목학회 집필자, 자문 및 평가심의위원, 그리고 국토해양부 담당자 등

여러분의 노고에 진심으로 감사드립니다.
