ROMA : state assessment of road markings in Denmark, Norway and Sweden : results from 2019

ROMA : en studie av vägmarkeringars tillstånd i Danmark, Norge och Sverige : resultat från 2019

Assessments of the performance of road markings is carried out regularly to various degrees in the Nordic countries. The main aim of the Nordic road marking assessment study is to show possible differences in road marking performance between Denmark, Norway and Sweden. Possible differences between road marking performance, dependent on region, country, type of road and AADT (Annual Average Daily Traffic) are studied. Furthermore, a comparison between the TEN-T and the non-TEN-T road network is made. As 2019 is the third year of the project, a comparison between the results for 2017, 2018 and 2019 is also made. A Nordic certification system for road marking materials has recently come into force. In Denmark it started in 2017, in Norway 2018 and in Sweden in 2019. This means that a documented product approval (i.e. certification) will be required for the material used on roads managed by the national road authorities. The requirements are introduced successively as the existing contracts expire. Therefore, one aim is also to study the road marking quality before and under the introduction of the new certification requirements. Continuous assessments give the opportunity to react and adjust the requirements in the future, if the performance does not develop as expected. The study is based on physical mobile road assessment measurements carried out in Denmark, Norway and Sweden by Ramböll. In total 71 road objects were measured in Denmark, 124 in Norway and 500 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.
