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.

使用简化的逻辑描述生成复杂的道路网络以验证自动驾驶汽车

仿真是验证和验证自动驾驶功能 (ADF) 的重要组成部分。在模拟城市驾驶场景时，模拟地图是重要的组成部分之一。通常，这些道路网络的生成是一项耗时且手动的工作。此外，通常需要不同交叉路口或路段的许多变体，以确保在向公众发布这些功能的过程中可以验证 ADF。因此，在本文中，我们提出了一种易于维护和修改的逻辑道路网络描述的原型解决方案。这个概念旨在是非冗余的，以便不同数量的变化不会影响代码中的其他地方，因此地图的变化很简单。此外，对连接点的简单定义是工作的重点。交叉的道路是单独定义的，然后进行相关设置，最终自动生成交汇点。这个想法是从模拟地图的常用标准化格式中导出描述，以便从引入的逻辑描述中生成这种格式。因此，我们开发了一个命令行工具来生成标准化的模拟地图格式 OpenDRIVE。
