Abstract

Eight colors prescribed by the Enforcement Rules of the Road Traffic Act and the group standard were tested to secure the minimum recursive reflectance performance standards when drying and wetting. The results were calculated to be 260.8 (mcd/㎡·lux) when drying white and 154.6 (mcd/㎡·lux) when wet. Yellow was 67% compared to the white reflective performance when drying. Wet poetry was 79 % and 59 %, respectively. In the case of blue, it was 64% in the case of white versus 72% in the case of white. Wet poetry was 63 % and 72 %, respectively. The range of changes in reflective performance during wetting was higher than when drying, and the absence of glass grains was similar to the previous results. The new colors also have a standard value of more than 50% compared to the white color in red, orange, pink, light green, and green. Based on this, it was estimated that the minimum reflective performance criteria according to the color of the road markings would form the basis for the enforcement rules of the Road Traffic Act.

도로교통법 시행규칙과 단체표준에서 정하고 있는 8가지 색상에 대해 건조 시와 습윤 시의 최소재귀반사성능 기준 확보를 위한 현장실험을 실시하였으며, 백색 건조 시에는 260.8(mcd/㎡·lux), 습윤 시에는 154.6(mcd/㎡·lux)으로 결과가 산출되었다. 황색의 경우는 건조 시 백색의 반사성능 대비 황색, 가호1호에서는 67%, 가호2호에서는 63% 수준이다. 습윤 시는 각각 79%와 59% 수준으로 나타났다. 청색의 경우에는 백색대비 가호1호에서는 64% 수준이며, 가호2호에서는 72%이다. 습윤 시는 각각 63%와 72% 수준으로 나타났다. 습윤 시의 반사성능 변화 폭이 건조 시보다 높으며, 유리알이 없는 경우도 이전의 결과와 비슷하게 나타났다. 신규색상이 적색, 주황색, 분홍색, 연한 녹색, 녹색의 경우에도 백색 대비 50% 이상의 기준값을 가지는 것으로 분석되었으며 이를 토대로 도로교통법 시행규칙에 노면표시 색상에 따른 최소반사성능 기준 마련의 토대가 될 것으로 판단된다.
