IEEE P2846a

Amendment Standard - Active - Draft.
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).

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.
Government and Industry alike need an open, transparent, and technology-neutral standard that provides guidance useful for evaluating the performance of an ADS. This guidance consists of a minimum set of assumptions with bounds on reasonably foreseeable behaviors of other road users used in the development of safety-related models.
