The colored road surface guide lines have been proven to significantly reduce the occurrence of traffic accidents. However, these guide lines have been currently applied sequentially only on roads that meet the installation criteria designated by the Ministry of Land, Infrastructure, and Transport. Furthermore, existing navigation systems such as legacy navigation and HUD (Head-Up Display) have demonstrated errors or ambiguities in delivering route information, highlighting the need for a clearer method of guiding drivers. In this paper, we propose a lane detection and masking technique that integrates the features of AR HUD (Augmented Reality Head-Up Display), a technology gaining attention in vehicle convenience systems, with the characteristics of colored road surface guide lines. The proposed technique detects and classifies lanes based on their color and lane detection results, then performs road masking using the classified lanes. Experimental results show that the proposed technique masked approximately 70% of the lane area. This enables drivers to receive real-time images of the masked route they should follow, offering an experience similar to constantly visualizing colored road surface guide lines. We expect that this approach will provide more intuitive information and improve driver convenience. Future advancements in this masking technique will further contribute to enhancing both convenience and safety for drivers.

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.
