Development of Road Marking Tester : status of RMT version 2 (English)
In 2004 the Swedish Road Administration initiated the development of a mobile instrument which measures, not only the retroreflectivity of dry road markings, but also other road marking parameters of interest. This study would end up in 2008, and so it did. However, such a development project should continue, as new components, useful for the measurement system, will show up in the future. As an example, a new generation of reflectometer is on the market and others will probably be on the market soon. This report accounts for the status of Road Marking Tester Version 2 in November 2009. The development of RMT 2004-2008 has been described in VTI Report 611. The measurements during this period of time showed that, from mobile measurement of the retroreflectivity of dry road marking and its mean profile depth (MPD), it is possible to predict the retroreflectivity of wet road marking with an accuracy that may be acceptable. Furthermore, the skid resistance, the thickness and the geometry of the road marking could be predicted from mobile measurement, using RMT. However, the prediction model regarding skid resistance of new road markings showed poor accuracy. Finally, some few measurements indicated that it should be possible to predict the daylight luminance coefficient using a modified optocator. Therefore, the work in 2009 focused on the development of prediction of new road marking skid resistance and daylight luminance coefficient.
