Functional Structuring of Road Networks

Transport network planning determines the form of transport networks and the characteristics of the network elements. A common concept in road network planning is the structuring of roads depending on the function of the road. In network planning transport planners therefore determine the form of a network not only by adding new network elements but mainly by assigning a function to a road which then influences the road design. The paper presents an approach for a functional structuring of road networks as it is described in the German Guideline for Integrated Network Planning. It describes the general methodology of the approach and shows some examples applying the methodology.
