Traffic Junctions

The STRASSENHAUS concept for traffic junctions is based on other principles to cross large flows of traffic without using traffic lights:

1. Traffic is subdivided according to classes of vehicles, only passenger vehicles use the upper levels.

2. An intermediate level is located between STRASSENHAUS and at-grade road.

Preferably, the intermediate level is equipped with a roundabout. While the at-grade intersection has 32 points of conflict, the roundabout level only has 8 points of conflict and the STRASSENHAUS level only 2 points of conflict.

Figure 1: Die STRASSENHAUS - Verkehrsebenen

The following series of figures (2 to 6) illustrates this concept:

Figure 2: At-grade road

Figure 3: Roundabout on intermediary level

Figure 4: STRASSENHAUS level

Figure 5: Junktions with superstructure, Var. 1

Figure 6: Junktions with superstructure, Var. 2

If structures are build over intersections the entrances and exits are mostly ramps. The main feature of a great group of these constructions is the integration of an intermediary level in form of a roundabout. The roundabout can be reached both from the at-grade area as well as from the upper road level of the STRASSENHAUS via road ramps. This entire construction is enclosed by building elements so that it forms a multifunctional building. The series of figures (2 to 6) shows a design of structures which are build over an intersection.

A total of 12 entrance and exit ramps is integrated in this traffic junction according to our concept.
