TSC
Generating evidence for the verification and validation of automated driving systems using classical methods often requires a large amount of ressources and thereby constitutes a major hurdle for the homologation.
TSC toolchain for efficient scenario analysis (TSC2CARLA)
The Traffic Sequence Chart (TSC) toolchain, also referred to as TSC2CARLA, is a software tool that enables efficient simulative analysis and testing in complex and open operational domains.
As one of the first in the scientific community, TSC2CARLA supports the derivation of abstract traffic scenarios and their subsequent analysis. Based on the criticality analysis method, TSCs are specified and converted into standardized simulation formats. This includes identification of functional scenarios that represent a given criticality phenomenon, formalization of these as TSCs with the help of an editor, including world model and symbol library, solving the constraint system (described by the TSC) over the world model and variation within the solution spaces found, mapping of the concrete scenario found as a combination of the scenario description languages OpenDRIVE®/OpenSCENARIO®, and a subsequent simulation using the open source simulator CARLA. To achieve the goal of efficient testing and analysis, novel approaches with respect to the recording and modular frameworks with respect to the computation of criticality metrics have been integrated. Requirements for TSC-based testing were collected in the VVMethoden and SET Level projects together with the industry.
