Abstract
This study analyses the performance of road markings at seven test fields in the Nordic region. The seven test fields used precisely the same road marking materials and had an identical layout in accordance with EN 1824. The principal objective was to investigate whether the performance of a test field can be generalised to make it applicable to other test fields. The performance was studied through field measurements of the retroreflection, luminance coefficient/factor and thickness of the road markings on three occasions over a two-year period for five different road marking materials. The aim of the statistical analysis was to identify performance similarities for the different materials at the seven different test fields. (A)
