IEEE Standard for Assumptions in Safety-Related Models for Automated Driving Systems

This standard applies to road vehicles. It defines a minimum set of reasonable assumptions and foreseeable scenarios that shall be considered in the development of safety related models that are part of an automated driving system (ADS).

P2846a

Standard for Assumptions in Safety-Related Models for Automated Driving SystemsnAmendment: Additional scenarios and road users

This standard applies to road vehicles. This standard expands upon the work presented in IEEE 2846-2022 by providing additional scenarios and road users. For the additional scenarios and road users, this standard defines a minimum set of assumptions regarding reasonably foreseeable behaviors of other road users to be considered in the development of safety-related models for an ADS. The scenarios reflected in this standard include those related to road geometry changes (e.g.,lanes merging), and specific behaviors of other road users (e.g., lane change). This standard further provides guidelines for the composition of more complex scenarios and associated assumptions based on the identified initial set. This standard does not prescribe any specific on-road behaviors expected of an ADS when encountering any of these additional scenarios or road users. Compliance with this standard does not guarantee the safety of the overall system.

Recommended Practice for the Application of Assumptions on Reasonably Foreseeable Behavior of Other Road Users

IEEE 2846-2022 defines, for a set of initial scenarios, a minimum set of assumptions on the reasonably foreseeable behavior of other road users. This recommended practice provides guidelines for using the IEEE 2846-2022 standard during development and testing of Automated Driving Systems (ADS). Specifically, it covers: (i) Approaches to identify the applicable IEEE 2846-2022 scenario(s), associated scenes and Operational Design Domains of interest, and safety-relevant agents; (ii) Approaches for determining the applicability of assumptions for the given scenario(s)/scene(s) and safety-related agents (from (i) above) and for updating these assumptions across the temporal evolution of a scenario; and (iii) Approaches to qualify and validate assumptions (i.e., toward identifying values/ranges) from IEEE 2846-2022 considering different kinds of performance targets of interest. Compliance with this recommended practice does not guarantee the safety of the overall system.
