Group 1a: Traffic scenarios VMAD-03-10 Group 1a: Traffic scenarios

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

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

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

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

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

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

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

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)
