  Simulation is a valuable building block for the verification and validation
of automated driving functions (ADF). When simulating urban driving scenarios,
simulation maps are one important component. Often, the generation of those
road networks is a time consuming and manual effort. Furthermore, typically
many variations of a distinct junction or road section are demanded to ensure
that an ADF can be validated in the process of releasing those functions to the
public. Therefore, in this paper, we present a prototypical solution for a
logical road network description which is easy to maintain and modify. The
concept aims to be non-redundant so that changes of distinct quantities do not
affect other places in the code and thus the variation of maps is
straightforward. In addition, the simple definition of junctions is a focus of
the work. Intersecting roads are defined separately, are then set in relation
and the junction is finally generated automatically. The idea is to derive the
description from a commonly used, standardized format for simulation maps in
order to generate this format from the introduced logical description.
Consequently, we developed a command-line tool that generates the standardized
simulation map format OpenDRIVE.
