국도 24호선과 35호선 도로선형에 관한연구

Abstract

본 논문은 도로의 평면 및 종단선형에 관한 연구를 선형설계 이론과 교통공학적 측면이론에 대하여 살펴본 후 기존 시공된 국도 24호선과 국도 35호선 일부구간 도로를 비교 분석하였다. 도로 시설기준에 미달된 곳으로 국도 24호선은 평면선형 16개소, 종단선형 6개소이고, 35호선은 평면선형 7개소, 종단선형 4개소로 조사되었으며, 도로시설 기준에 미달된 지점에 대해 교통공학 이론에서 다루는 시거에 대해 조사한 바 마찬가지로 확보되지 못했음을 알 수 있었다. 도로 시설 지준에 미달되고 시거를 확보하지 못한 지점에 대해서는 노선의주변 사정에 따라 곡률조정, 노견 또는 중앙 분리대 확폭, 미끄럼 방지 포장, 운전자 주의 환기 표지, 오르막 차선 설치등의 조치를 하거나 경우에 따라서는 새로운 노선의 건설이 필요하다.

In this paper, the research about the plane of road and the vertical section of road were made in aspects to the sector design theory and the traffic engineering-concerned theory. Then some section road of already established No. 24 and No.35 national road were examined and analyzed. The sites which do not fit to the road facility standard are examined as 16 plane sections and 6 vertical sections in No. 24 national road and 7 plane sections and 4 vertical sections in No.35 national road, and above places are also turn out to be improper to the sight distance that traffic engineering theory deals with. The place where is under road facility standard and dose not have proper sight distance should be taken step according to enviromental condition of road such as a curvature fitness, a road shoulder or a median strip width, a slip prevention paving, a driver notice signpost, a climbing lane installation. In particular case new road building is necessary.
