response: "Response from the Ministry of Infrastructure and Spatial Planning\nThe\
  \ characteristics of road markings and the materials from which they can be made\
  \ are defined by the Regulation on traffic signalling and traffic equipment on public\
  \ roads (Official Journal of the Republic of Slovenia No 46/2000, as amended) and\
  \ the European standard SIST EN 1436. The materials of which the markings must be\
  \ made are specified by the Regulation only for motorways, expressways and roads\
  \ with an average annual daily traffic exceeding 10 000 vehicles, while on other\
  \ roads the markings must be made of these materials only at certain specific locations\
  \ (roundabouts, humps) where it is prescribed that they be made of materials for\
  \ thick-film markings. The choice of the type of material has a significant influence\
  \ on the durability and characteristics of the markings.\nSIST EN 1436 does not\
  \ define the characteristics of markings according to the category of road or the\
  \ amount of traffic on it, but rather classifies them into categories (classes).\
  \ With regard to the characteristics of the markings, it should be noted that the\
  \ reflectivity (night visibility) of the markings on a dry carriageway (RL) is only\
  \ one of the characteristics.  At least as important as the reflectivity of the\
  \ markings on a dry carriageway is their reflectivity on a wet carriageway (RW)\
  \ or in the rain (RR). Since the overall visibility is then significantly reduced,\
  \ the more the driver needs the markings to orientate where he is on the carriageway.\
  \ Conventional markings made of thin-film marking material - paint (most roads still\
  \ have markings made of this material) - are quickly covered by a thin layer of\
  \ water during rain, which prevents their reflectivity. Other characteristics of\
  \ the markings (slip resistance, light factor, day visibility and chromaticity coordinates)\
  \ also have a certain influence on the safe flow of traffic.\nIn accordance with\
  \ this standard, the national road managers have in place guidelines on the characteristics\
  \ and quality control of longitudinal and transverse markings on the carriageway,\
  \ which specify the required retro-reflecting characteristics in dry conditions,\
  \ namely:\n for new markings (measurements to be taken between 3 and 14 days after\
  \ the application of the material and the release of traffic), where the RL value\
  \ should be \u2265 200 mcd/luxm2 (R4), for markings under warranty (usually 3 years,\
  \ in more congested locations such as, e.g. At the end of the lifetime (when the\
  \ values reach this level, the signs should be renewed), where the RL values should\
  \ not be less than 100 mcd/luxm2 (R2).\nWith regard to the required levels used\
  \ for the establishment and maintenance of ground markings on national roads, the\
  \ RL values reach above 150 mcd/luxm2 for a good part of their lifetime.\nThe EN\
  \ 1436 standard leaves the choice of the characteristics of floor markings on a\
  \ particular road to the individual Member State to regulate by regulation, which\
  \ is not yet regulated at national level. A new Regulation on Traffic Signals and\
  \ Traffic Equipment is under preparation, which will also include requirements on\
  \ the minimum characteristics of ground markings according to the category or traffic\
  \ load of the road.\nEuropean countries have very different requirements for the\
  \ characteristics of ground markings. Achieving higher values for individual characteristics\
  \ in the initial phase is not problematic, but raising the values of individual\
  \ characteristics over the lifetime of ground markings can have a significant impact\
  \ on maintenance costs. However, as the lifetime characteristics of thick-film markings\
  \ in particular are influenced by a large number of factors, it is not easy to decide\
  \ on minimum values for individual characteristics.\n "
