Abstract Broken-line markings on the freeway have been installed for delineation and lane division, which together are expected to potentially reduce the number of traffic crashes. Although these functions are clearly dependent on visibility, the practical application of broken lines differs greatly worldwide in terms of the ratio of the line segment to the gap length or the width of the markings. On Korean freeways, existing broken-line markings consist of 8-m line segments and a 12-m gap with a width of 15 cm, although the reasoning for these dimensions is not known. The present study began with the field installation of diverse broken-line marking alternatives under the regulated ratio of the line segment to the gap segment—that is, 1:2 in Korea. Using the installed markings, a visibility experiment with subjects riding in a vehicle moving at a speed of 100 km/h was performed. From this study, it can be concluded that the existing broken-line markings on Korean freeways are not ideal in terms of visibility and that broken-line markings with 6-m line segments and a 12-m gap with a width of 13 cm is preferred in terms of visibility. This alternative was recommended to later become the new nationwide standard for Korean freeways.
