Development of Low-Cost Diagnostic System for Road Markings by Using In-Vehicle Camera

In Japan, road markings are greatly damaged by snow-removal operations. In order to effectively maintain and manage the markings within limited budget and personnel, it is necessary to evaluate the damages frequently and quantitatively judge the repainting using a low-cost system. The purpose of this study is to develop a diagnostic system for road markings considering both visibility in the daytime and nighttime by using the road surface image photographed by the in-vehicle camera. First, the stripping ratio of road marking was estimated by image features. To evaluate the nighttime visibility, the reflectivity measured by equipment was estimated from the relationship with stripping ratio. Second, the authors conducted a questionnaire survey and clarified the relation between stripping ratio and daytime visibility. Finally, based on the above results, the authors have proposed the road marking condition index (RMCI) and the repainting criterion considering the daytime or nighttime visibility.
