Providing lighting characteristics of lightness, brightness and sharpness of road markings

Currently, as the lighting characteristics of road markings used indicators of reflection and color. The indicator of light reflection when measured by a reflectometer is normalized as an absolute value, however, the perception of the driver and other road users (pedestrians, wheelchair users, cyclists) of road markings is carried out by means of vision relative to the surrounding background. Meanwhile, there is virtually no applicable regulatory document GOST 26824-86 Buildings and structures. Methods of measuring brightness, which establishes methods for measuring the brightness of working surfaces in buildings and structures, road surfaces of streets, roads and squares, facades of buildings and structures to determine its compliance with established standards. It is proposed to introduce into the regulatory framework for road markings indicators of brightness, contrast and sharpness.
