The visibility of road markings in headlight illumination is greatly reduced during the winter. This is serious, as it is during this dark period that they are of great importance for night-time traffic safety. In order to investigate the deterioration and to draw up a proposal on how to increase the visibility of dry road markings in winter-time, the specific luminance of dry road markings was measured during three winters on a total of six test sites in Sweden and Denmark. The results indicated that the reduction in visibility of dry road markings during winter-time is due to wear caused by studded tires. A law against studded tires would increase the visibility of road markings during the winter. A continuous edge line, instead of a broken line, would reduce wear and consequently increase visibility.
