QUANTIFICATION OF THE ROAD ADHESIONPROPERTIES BY OPTICAL METHOD

The paper is the result of continuation to measure the total projection dealing with the determination of adhesion of the tires with the road. There is proposed and tested a method that could be useful for online determination of adhesion properties and the resulting increase safety and smooth operation. The chosen method consists in indirect optical measurements. This method is carried out to measure on dry, wet and snow and ice-covered roads. The result is a statistical evaluation along with a graphical representation of the frequency histograms for all individual shades and design surfaces for use in practice
