IEEE | 2022 |
New IEEE Standard – Active – Draft. This standard applies to road vehicles. Within its Normative portion, 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 automated driving systems (ADS).

39 | 5. Common attributes from contributed safety-related models 5.1 Safety-related model attributes(verifiable or demonstratable via inspection 5.1.1 Incorporates the laws of physics |
40 | 5.1.2 Accommodates acceptable risk 5.1.3 Supports reasonably foreseeable scenarios 5.1.4 Focuses on motion control 5.1.5 Incorporates assumptions 5.1.6 Based on current position, heading and velocity of other safety-relevant objects |
41 | 5.1.7 Supports prioritization of safety objectives 5.1.8 Is sensitive to adjustment in parameter values 5.1.9 Supports diverse safety-relevant objects 5.1.10 Supports emergency maneuvers |
42 | 5.1.11 Defines a hazardous situation 5.1.12 Defines proper responses 5.1.13 Differentiates between initiator and responder For example, in a proper response definition, a safety-related model differentiates what actions the initiator and the responder should take, respectively, that would be an instantiation of this attribute. 5.1.14 Supports directional flexibility 5.1.15 Supports occlusion scenarios |
43 | 5.1.16 Defines a safety envelope 5.1.17 Considers reasonably foreseeable events regarding right of way 5.1.18 Supports a theoretical outcome of no collisions upon universal adoption 5.1.19 Supports formal verification |
44 | 5.1.20 Supports creation of performance indicators 5.1.21 Can be expressed in formal notation 5.1.22 Is transparent 5.1.23 Considers weather-related environmental conditions and road surface conditions 5.2 Safety-related model attributes demonstratable via validation 5.2.1 Validated through empirical evidence and industry best practices 5.2.2 Enables the ADS-operated vehicle to navigate safely |
45 | 5.2.3 Exhibits a reasonable level of caution 5.2.4 Considers human violations of traffic rules Safety-related models can take into consideration that sometimes human road users may intentionally or unintentionally violate traffic rules in specific scenarios. While there does not exist a universal and complete list of possible human violations of traffic rules, the safety-related model can consider those that are reasonably foreseeable in the ODD. 5.2.5 Supports regional differences in behavior 5.2.6 Incorporates empirical, evidence-based methods |
