This report summarizes the results of the condition assessment of road markings in Sweden 2012. The measurements have been carried out using the mobile system Road Marking Tester which mainly is built up of a reflectometer and an optocator. The two units register the retroreflectivity and the macro-texture of the road marking, respectively. From these measures, the retroreflectivity of a wet road marking can be predicted, which has been done on roads with ADT > 4000 vehicles. Measurements were accomplished on 292 objects in total, each approximately 10 km of length. The objects were chosen randomly and spread all over Sweden. In each object three longitudinal road markings were measured: two edge lines and one centre- or laneline.
