Trajectory Supervisor

The safety assessment module is a python-based online verification framework consisting of multiple sub-modules. The safety checks serve as an independent check for generated motion primitives, with the goal of reducing the risk of not properly handling safety critical behaviours that did not occur during development. Furthermore, the framework can be used to pinpoint critical scenarios or time intervals during development.

To serve these purposes, the safety assessment module rates incoming trajectories with regard to their safety. The trajectories can either be provided directly by the planning module on the target device or for testing purposes (e.g. CI jobs) via stored scenario files.

This software is provided as-is and has not been subject to a certified safety validation. Autonomous Driving is a highly complex and dangerous task. In case you plan to use this software on a vehicle, it is by all means required that you assess the overall safety of your project as a whole. By no means is this software a replacement for a valid safety-concept. See the license for more details.
