36. The representative of United Kingdom recalled the challenge of assuring the safety of these new vehicles as well as the ideas proposed by the industry (multi-pillar approach) and IWG on VMAD. He mentioned several activities related to scenario databases around the world and highlighted that industry were developing their own databases for research and product development purposes. He proposed that WP29 should consider the need for a separate independent database for regulators with the direct oversight of the contracting parties and the ECE. An expert from the United Kingdom introduced WP.29-178-29 which presents their work on a Multi-User Scenario Catalogue for Connected and automated vehicles (MUSICC). He explained what was to be understood as a scenario and presented the vision proposed by United Kingdom: a scenario-based certification process, and proposed that the scenario catalogue would be stored at ECE, for the purpose of simulated tests, physical tests and other processes leading to the certification of a vehicle. He raised the question whether this vision was shared.

37. The representative of France supported the proposal made by the representative of United Kingdom. He welcomed the effort made to develop a common language for descripting and parametrizing scenarios that could be classified according to their criticality. He mentioned WP.29-178-20, prepared by the representative of OICA, providing information on a number of activities in various countries and encouraged them to continue this compilation work.

38. The representative of Japan, Co-Chair of the IWG on VMAD, confirmed that this vision is shared by WP.29 because the framework document adopted at this session of WP.29 included it and allocated it to VMAD IWG. He recalled the current IWG activities and invited the experts of MUSICC to contribute to IWG on VMAD.

39. The representative of Germany expressed interest in this matter and agreed to investigate. He recalled that establishing a database was difficult and that such activities could build on the electronic database for the exchange of type approval documentation (DETA) to be hosted at ECE.

32. The representative of ITU presented WP.29-191-22, a proposal for establishing Terms of Reference (ToR) for an effort to analyse if new data catalogues were needed, e.g. a data catalogue for Automated Driving Systems (ADS). He stated that creating a data catalogue required strong communication between the user and IT world, and therefore, the ToR should be developed from the technical-organisational side.

33. The representative of France welcomed the proposal by ITU and supported having further discussions on this item, to reach agreement on the appropriate timing and the potential content of such catalogues, among others. He informed WP.29 that France had a database for different automated driving scenario that they would present at the next IWG on Validation Method for Automated Driving (VMAD) meeting.

34. The representative of Japan asked for clarification if this item had been already discussed in subgroup 1 (SG1) of the IWG on VMAD and stressed that duplication of work should be avoided.

35. The representative of ITU confirmed that this topic had been discussed at SG 1 of the IWG on VMAD and stressed that this work was necessary to support the IWG on VMAD. He stated that the IWG on VMAD discussed that there could be the need for a scenario catalogue, but it would not be created by the IWG on VMAD due to time constraints, and that there would be difficulties to maintain such catalogue.

36. The representative of the United Kingdom of Great Britain and Northern Ireland reminded WP.29 of WP.29-178-29 and stated that other catalogues, created by other groups, already existed. He highlighted that United Kingdom was still considering whether it is necessary for the UNECE to have a dedicated scenario database and highlighted recent discussions in VMAD. He pointed out that if WP.29 would agree to create a catalogue, it needed to be considered how it would be used, and who would take responsibility and take care of the maintenance.
