Percentages of vision

The Wizard system’s View lengths target category belongs to the Traffic Data Register’s Code figures and traffic data set. The target category “sight lengths” was in the road register as TL 109 View percentages. The length of the sections where the length of the vision exceeds 150 metres is added together and the percentage of the total length of the road section is calculated to the target category. Correspondingly, the percentages seen above 300 and 460 metres are calculated. The actual measurement results can be found in the target category Sight Length.
