ROMA : en studie av vägmarkeringars tillstånd i Danmark, Norge och Sverige - resultat från 2017 (Swedish)
Abstract [en]

Assessment of the performance of road markings are carried out regularly to various degrees in the Nordic countries. During the coming years, the Nordic certification system for road marking materials will come into force, which means that a documented product approval (i.e. certification) will be required for use of the material on roads managed by the national road authorities. The requirements are introduced successively as the existing contracts expire. The aim of this project is to monitor and follow up how road marking quality is influenced by the introduction of the certification system in Denmark, Norway and Sweden. If the performance does not develop as expected, continuous assessments give the opportunity to react and adjust the requirements in the future. Furthermore, the aim is to show possible differences in road marking performance between the three countries, similar regions in the three countries and TEN-T-roads.

The study is based on mobile road assessment measurements carried out in Denmark, Norway and Sweden by Ramböll AB. In total 71 road objects were measured in Denmark, 101 in Norway and 436 in Sweden. The following variables were studied: retroreflectivity of dry and wet road markings, relative visibility of dry and wet road markings, relative pre-view-time (pvt) of dry and wet road markings and cover index.

In conclusion, there is no large difference in road marking performance in the three countries. The only significant difference is the poor visibility of edge lines on two-lane roads in Sweden and the good performance of wet road markings in Norway.

Abstract [sv]

Bedömning av vägmarkeringarnas tillstånd genomförs regelbundet i olika omfattning i de nordiska länderna. Under de närmaste åren kommer ett certifieringssystem för vägmarkeringsmaterial att träda i kraft i Norden, vilket innebär att ett dokumenterat produktgodkännande (certifiering) kommer att krävas för att materialet ska få användas på vägar som förvaltas av de nationella vägmyndigheterna. De nya kraven införs succesivt efter att de befintliga entreprenaderna löper ut.

Det huvudsakliga syftet med föreliggande studie är att med tillståndmätningar, dels under 2017 skaffa en bra bild av vägmarkeringarnas funktion innan det nya certifieringssystemet börjar tillämpas, dels med fortsatta mätningar under 2018 – 2021 studera utvecklingen och effekterna av certifieringens införande. Syftet är också att visa eventuella skillnader i vägmarkeringsprestanda mellan de tre länderna som ingår i projektet: Danmark, Norge och Sverige.

Studien baseras på mobila tillståndsmätningar utförda i Danmark, Norge och Sverige av Ramböll AB. Totalt mättes 71 vägobjekt i Danmark, 101 i Norge och 436 i Sverige. Följande variabler studerades: retroreflexion för torra och våta vägmarkeringar, relativ synbarhet för torra och våta vägmarkeringar, relativ pre-view-time (pvt) för torra och våta vägmarkeringar samt väg-markeringens täckningsgrad.

Sammanfattningsvis är det ganska små skillnader i vägmarkeringarnas funktion när man jämför Danmark, Norge och Sverige. Undantagen är den relativt låga synbarheten hos kantlinjerna på svenska tvåfältsvägar, trots en hög retroreflexion, och en hög synbarhet hos våta vägmarkeringar i Norge.
