The database represents a logical model of the current road network of Chemnitz, which consists of the elementary building blocks nodes and edges. The natural course of the road is modelled by polygon trains (lines), with a polygon train usually beginning or ending at a junction and/or junction. Such a section is called the edge. One edge has no direction and is limited by two nodes (see object class Road Net_Knoten).
