Mobila mätningar av vägmarkeringars retroreflexion i Sverige 2006: en översikt
2007 (Swedish)Report (Other academic)
During the year of 2006 a large number of mobile measurements of road marking retroreflectivity were carried out in Sweden. In total, the retroreflectivity of dry markings was measured on 386 road stretches. Additionally, indirect measurements (predictions) of retroreflectivity of wet road markings were made on 25 road stretches. The measurements had different aims and were not carried out in the same way everywhere, which means that it is difficult to compare results from different regions and, in some cases, even results within the same region. The method for selection of road stretches to be measured and the length of the road stretches have varied between the regions and different kinds of instruments have been used. In three regions also the function of wet road markings has been predicted. All of this means that the results should be interpreted with some caution and that making comparisons between the regions is not meaningful. It is obvious that there is a lot to gain by co-ordinating the function measurements of road markings in the future. Naturally, the regions themselves must decide the extent of the function controls, but when measuring is decided, the strategy for measurement should be managed in such a way that comparisons between counties and regions can be made, and desired issues can be solved. In general, there is a need to consider if the strategy used since the year of 2000 is good.
