Group 1a: Traffic scenarios

2. Scope of the traffic scenario group
Let’s not limit this

3. Definition Traffic scenario:
Traffic scenario's (in this context) are digitilized traffic situations that can be manipulated by parameters and are used for simulations
(to be discussed)
We need to include the validation on the track and road in this definition
We need to align the definition with SOTIF

4. A. The outcome of "traffic scenarios"
Relevant driving situation(can be different for systems) to validate by different means (to be defined) the performance of AV’s
Within the ODD
Containing boundaries of the ODD
Demonstrating the way the vehicle acts (also when reaching the boundaries)
…not complete
Pass/fail criteria
What do we want to avoid?
5g, 20g and others
Scenario Database
Definition
Free availability
Standard

5. The scenario’s should cover
We realize that scenario’s do not proof the safe behavior of the AV under all conditions. We need a common understanding on this.
The scenario’s should cover
Sensor perception
Decision making (also complex situations)
Vehicle dynamic response

6. B. Define the underlying questions to be answered by "traffic scenarios"
How do scenario’s contribute to the approval of AV’s?
How does scenario testing contribute to safety in traffic?
What is the residual risk of fatal crashes in case the AV is involved?
(needs to be worked out)
Related to inpreventable in the Japanese presentation
Not intended as pass/fail, but for measuring
Does the scenario’s only cover operational safety or also functional safety?(scope)
For what kind of validation matter is the scenario used? (Simulation, track…)
To be completed

7. C. Indicate which persons/organizations need to be involved in this group
October

8. D. Collect all available proposals/information and translate this into a draft for the next VMAD
Accidentology information
These situations could be covered in the scenario’s (if relevant to AV’s)
Expert opinions on
Empirical knowledge on accidents
Parameters of the difficult situation
Pegasus
MOSAR
Needs to be completed
GRVA 86 document

9. Additional
AV’s can create new traffic scenario’s of critical situations in the database.
This critical situations can be evaluated by a national safety board to improve the safety (either vehicle, infra or other)
