해외 교통노면표시 디자인 지침의 비교분석을 통한 실용적인 한국 교통노면표시 문자 디자인 방향 제안

Korea’s pavement marking letters have raised questions about legibility and consistency arising from the lack of clear design manuals. There have been previous studies for solving problems, but the ideal approaches presented in the studies is beyond the scope of current construction methods or regulations. In order to solve these problems, this study aims to establish criteria for analyzing the compliance with the perspective distortion, legibility, readability, consistency, and suitability with the Korean construction environment based on the analysis of Korean regulations, related guidelines and construction environment. After comparing and analyzing the related items of the design manuals for overseas pavement marking design selected by these analysis criteria, the following design directions are presented. First, in the specification of a character, as the driver moves farther away from the observation point, the distance between the trails is gradually increased to correspond to the perspective. Second, the standard of character transformation is based on the specified speed, not the road width. Third, the grid system is used to accommodate the construction environment of Korea. Fourth, it reflects Korea's reading culture from the far side to the near side. Finally, when the number of characters applicable to the width of the road is large, narrower the kerning is applied, and when the number of characters is small, the kerning is applied wider.
