An Open-Source Scenario Architect for Autonomous Vehicles

The development of software components for autonomous driving functions should al-ways include an extensive and rigorous evaluation. Since real-world testing is expensive and safety-critical - especially when facing dynamic racing scenarios at the limit of handling - a favored approach is simulation-based testing. In this work, we pro-pose an open-source graphical user interface, which allows the generation of a multi-vehicle scenario in a regular or even a race environment. The under-lying method and implementation is elaborated in detail. Furthermore, we showcase the potential use-cases for the scenario-based validation of a safety assessment module, integrated into an autonomous driving software stack. Within this scope, we introduce three illustrative scenarios, each focusing on a different safety-critical aspect.
