Traffic calming is a current issue in Germany and Korea.
In Germany, especially in the 1980s, various structural elements of traffic calming were experimented with, mainly thresholds, plasters or with the swinging or narrowing of the roadway.

Most of these constructive elements, however, were referred to as “harassment” in both the public and professional circles, and in the end did not prevail (throughout the country). As a consequence, the methods of traffic monitoring and punishment remained.

A new approach is the reconstruction of roads according to the shared space approach, which (from a structural point of view) largely omits the separation of traffic types. This should be accompanied by increased mutual consideration, which in turn will lead to traffic calming.

In Korea, on the other hand, very many of the neighborhood streets have traditionally been built at a plain level: Pedestrians and motorists use the same space, and there are often more uses in the side areas that enliven the street space. The shared space principle is a standard situation here.

There are also constructional traffic calming elements in the form of bumps: These lead to less abrupt braking and acceleration processes than the thresholds known in Germany, but nevertheless ensure a lower speed level.

Within the framework of the living lab GO Karlsruhe, raised plateaus are applied in the form of temporary plateau pavements according to the Korean model, thus testing the transferability of the Korean approach to German roads. The results of the real experiment will be compared with the findings of the Korean researchers.
