This study presents a novel framework and open-source tools for simulating and managing connected and automated mobility (CAM) systems, taking into account their hierarchical nature and various levels of scheduling. The framework is based on a multi-layered network representation, which allows for efficient and accurate modeling of CAM systems at different levels of granularity, from macroscopic to microscopic. By employing this hierarchical approach, we achieve a balance between the level of detail in the representation and computational efficiency. Additionally, a spatial-discrete virtual track-based representation is introduced for precise vehicle dynamics modeling and for ensuring consistency with higher-level routing decisions. This facilitates individualized active traffic management for CAM applications. As part of our research, we have developed osm2gmns, an open-source package that allows users to …
