A general conclusion which can be drawn from the condition assessment 2013 is that the performance of road markings in Sweden cannot be approved when having the regulations in mind. Especially, this fact can be observed on high-trafficked roads, which imply that on these roads improved road marking maintenance is needed. During the period 5 May until 23 October 2013, measurement of road marking performance has been carried out in Sweden. A total of 294 objects, each including two edge lines and one centre or lane line, i.e. three road marking objects, have been monitored using mobile equipment. The aim of the condition assessment is primarily to get knowledge of to which extent the road markings fulfil the Swedish regulations. Furthermore, the results can form the basis for future allocation of funds for road marking maintenance; a poor road marking performance in a specific region might indicate that more maintenance is needed. Finally, the performance over years can be studied, as condition assessment has been carried out since 2000 in several counties. The measurements 2013 show that 45 percent of the road marking objects fulfilled the requirements in the Swedish regulations, regarding dry road marking retroreflectivity. The corresponding figure for wet road markings was 19 percent. With respect to dry road markings, Region Nord (North) had the largest part of road marking objects fulfilling the requirements, 73 percent, while only 15 percent were approved in Region Stockholm. In two counties repeated measurements were carried out: a 1st round in May 2013 and a second one in August/September the same year. These measurements showed an increase in retroreflectivity for most road marking objects. This result shows that the time of measurement should be considered when planning the condition assessment.
