Separation principle (traffic)
The separation principle is used in traffic planning to separate the traffic areas of motorized traffic, bicycle traffic and pedestrian traffic. This generally increases the evenness of the traffic flow.
The main disadvantage is that the separation of cyclists and motor vehicles in particular increases the risk of accidents, according to different studies (presumably because the principle of separation is interrupted at every junction and intersection). In addition, the separation principle means a high level of land consumption and road construction is significantly more expensive. The principle of separation is therefore being replaced in many places by the principle of mixing. A radical counter-attempt to the principle of separation is the shared space .
According to the British city planner Colin Buchanan, the horizontal separation of driving and walking traffic is one of three strategies for developing city centers, alongside the mixing principle and vertical separation . Therefore needs with regard to the functioning of city centers and their environmental balance exist between areas for the flowing and stationary traffic , areas for the delivery traffic , areas for public transport , areas for cyclists and pedestrians and land. The requirement also applies to the mixing principle .
