Is it possible to predict other performance parameters, such as wet road marking retroreflectivity,daylight luminance coefficient and skid resistance, from mobile measurements? The hypothesis isthat such predictions should be possible to accomplish by simulataneous measurement of dry roadmarking retroreflectivity and macro-texture.From mobile measurement of dry road marking retroreflectivity and macro-texture, empirical models forother performance parameters have been developed. The results show that it should be possible toassemble a mobile measurement system which can register all road marking performance parameters inthe regulations.Keywords:road marking, mobile measurement, retroreflectivity, skid resistanceISSN: Language: No. of pages:0347-6030 Swedish 40 + 1 Appendix
