ABSTRACT
The profession of transport planners made it their goal to keep the traffic flowing and thus to heal the organism. Professionally, transport planners were civil engineers specializing in traffic and transport infrastructure; they were technicians who had the task of ensuring that technical traffic systems functioned within cities. Transport planning served the concept of 'fluid' traffic that viewed traffic as blood pulsing through the city's veins. Planners believed that if each means of transport received its own separate position within the whole, then the flow would be secured. As early as the 1950s a new paradigm had thus been established in both German states. Transport experts were all of the opinion that transport types should be partitioned separately. In the 1980s, ecological concerns led to dramatic changes in the ideal paradigm. Traffic partition according to type was no longer the leading conception but rather, a varied approach to planning was meant to reduce the dominance of cars in traffic.
