GRVA-25-15
Report of the GRVA workshop on scenarios

The workshop on scenarios discussed scenario-related information-sharing procedures and exchange, including to facilitate implementation of regulations using scenario-based assessments, develop administrative procedures to gather scenario-related information from CPs and NGOs, identify useful information to share, and clarify scenario use needs. At the same time, the workshop explicitly excluded activities such as creating a scenario catalogue and/or database, developing regulatory scenarios, and developing methodologies to create and derive scenarios for regulatory purposes. The group discussed whether scenarios work should operate as a dedicated working group under GRVA or as part of an existing group, considering resource constraints and the importance of supporting WP.29 activities like ADS and ADAS regulations.
