Tillståndsmätning av vägmarkeringars funktion 2014

Mohammad-Reza Yahya

Measurements of road marking performance have been carried out from 21 May to 6 November 2014 on a sample of Swedish roads. The aim of the performance assessment is primarily to investigate to what extent the road markings fulfil the Swedish regulations. Besides, the assessment aims at comparing the road marking performance in different counties and regions, and to analyse the development over time, as performance assessments have been carried out to various extent since 2000. The results of the measurements in 2014 show that 39 per cent of the road marking objects fulfilled the requirements regarding dry road marking retroreflection. The corresponding figure for wet road markings was 21 per cent. With respect to dry road markings, Region Norr (North) and Region Väst (West) had the largest percentage of road marking objects that fulfilled the requirement, with 52 per cent each. Region Stockholm had the lowest percentage of road markings objects that fulfilled the requirements – only 12 per cent. Regarding wet road markings, the percentage of approved objects were 50 per cent in Region Norr (North) and in the range of 7–30 per cent in the other regions. A comparison over the years 2011–2014 shows a downward trend. The percentage of road marking length that fulfills the requirements for dry road markings has decreased from 70 per cent in 2011 to 60 per cent in 2014. The corresponding figures for the percentage of approved road marking objects are 52 per cent and 39 per cent, respectively. In four out of the six regions, the percentage of approved road marking objects has decreased from 2013 to 2014. In summary, the fulfilment of the requirements is in general low and there has been a downward trend since 2011. Furthermore, there is a substantial difference in results between the regions, where Region Norr (North), Region Väst (West) and Region Syd (South) have better results than the other regions. Region Stockholm has markedly worse results than the other regions. A total of 303 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 objects have been randomly selected, however in such a way that at least 14 objects per county have been included in the sample.
