[i] * (data of 2015) – data update in 2018 did not show a significant influence of the advertising act on the number and size of advertisements in relation to the data of 2015. The number of ads declined, which was connected with the following, e.g. some advertisers stopped their activity, an alternative – faster road was constructed and traffic was reduced in the studied area. The total advertising area slightly dwindled, and at the same time the mean area increased as a result of the change of the old and outdated form into a new one.

Examples of not harmonious solutions for the placement of advertisement carriers in relation to a landscape: A – unfavorable location of an advertisement – visual competition with a historic object; B – destroyed and outdated ads degrading a landscape; C – unfavourable location of an advertisement – competing visually with a protected landscape and information signs; D – information chaos.
