In the automobile industry there is a tendency to make faster cars. A presumable correlating aspect is the increasing average speed on the national highways. The design speed of the road should be introduced at high traffic intensities to the road users as the user speed. By doing so it can be prevented that the slowest traffic participant can determine the tempo for all traffic participants.
