The visibility of a road marking is dependent of its retroreflectivity. therefore, in order to ensure good visibility, there is a need of adequate maintenance routines. Furthermore, the road marking material must be of high quality, i.e. be resistant against wear from the traffic. The purpose of the study is to ensure good road marking visibility. If there is a difference in visibility between two or more coutries, this result should be explained. Is the difference due to the road marking material, maintenance routines, road marking area ect.? Moreover, the result can be used to distribute maintenance funds in such a way that the road marking quality will be similar in all countries. Denmark, Norway and Sweden participate in this project. |
