High-quality and highly visible ground markings are generally considered to be the most cost-effective methods to improve road safety. Analyses of the causes of road accidents show that one of the reasons is inadequate traffic signing on individual or entire road sections.  Studies to date show that the use of modern technologies and a methodological approach to the design and renewal of traffic signals can significantly reduce the number of accidents and thus increase the level of road safety. One preventive measure is to check the quality of the ground markings on the carriageway and thus increase their quality to the desired level. It is particularly important to monitor the night visibility values (retroreflection RL) because these values define the visibility of the ground markings at night and in low visibility conditions when the ground markings are an indispensable aid to the driver in determining the position of the vehicle on the road. For all road users, road markings are very important, as the clarity of the messages received by drivers from road markings directly affects the safety, speed and comfort of driving. I propose that the level of retroreflectivity (night visibility) of pavement markings on national and local roads be raised to a minimum level of 150 mcd (as in neighbouring countries) to ensure better road safety for us road users.
