• Authors: Anne Collin, Artur Bilka, Scott Pendleton, Radboud Duintjer Tebbens
• Abstract summary: The ISO/PAS 21448 guidance recommends a process to ensure the Safety of the Intended Functionality (SOTIF) for road vehicles. For the path planning function, defining the correct sequence of control actions for each vehicle in all potential driving situations is intractable. We establish that Rulebooks provide a functional description of the path planning task in an AV and discuss the potential usage of the method for verification and validation.

• Abstract: Autonomous Vehicles (AVs) are complex systems that drive in uncertain environments and potentially navigate unforeseeable situations. Safety of these systems requires not only an absence of malfunctions but also high performance of functions in many different scenarios. The ISO/PAS 21448 [1] guidance recommends a process to ensure the Safety of the Intended Functionality (SOTIF) for road vehicles. This process starts with a functional specification that fully describes the intended functionality and further includes the verification and validation that the AV meets this specification. For the path planning function, defining the correct sequence of control actions for each vehicle in all potential driving situations is intractable. In this paper, the authors provide a link between the Rulebooks framework, presented by [2], and the SOTIF process. We establish that Rulebooks provide a functional description of the path planning task in an AV and discuss the potential usage of the method for verification and validation.

• An Ontology-based Approach Towards Traceable Behavior Specifications in Automated Driving [0.0]
  We propose a Semantic Norm Behavior Analysis as an approach to specify the behavior for an Automated Driving System equipped vehicle. We use to formally represent specified behavior for a targeted operational environment, and to establish traceability between specified behavior and the stakeholder needs. Our evaluation shows that the explicit documentation of assumptions in the behavior specification supports both the identification of specification insufficiencies and their treatment.

  We introduce SAFE-SIM, a controllable closed-loop safety-critical simulation framework. Our approach yields two distinct advantages: 1) generating realistic long-tail safety-critical scenarios that closely reflect real-world conditions, and 2) providing controllable adversarial behavior for more comprehensive and interactive evaluations. We validate our framework empirically using the nuScenes and nuPlan datasets across multiple planners, demonstrating improvements in both realism and controllability.

We introduce DARTH, a holistic test-time adaptation framework for MOT.
