Control Measurements of Road Markings Retroreflection as a Quality Increasing Tool

The quality and quantity of drivers’ visual guidance in road traffic depends on the visibility and the reflective properties of road markings. Using the latest methods and procedures for testing the road markings, a high and consistent level of visibility can be achieved, and thus the safety level of individual roads may be raised. This paper analyses how the systematic retroreflection measurements of road marking can ultimately increase their quality. For that purpose road markings retroreflection has been continuously measured on six single carriageway state roads in Croatia over ten-year period using static measuring method. Between 2003 and 2010, measurements were conducted according to the Kentucky methodology and since 2010, according to the German regulation ZTV M02. The results of measurements in the ten-year period show an overall average increase in night-time visibility of road markings by 48.96% and 23.08% in their daytime visibility. Obtained results prove that the constant and systematic retroreflection testing of road markings can contribute to the enhancements in their quality.
