27. GRVA received a progress report from the expert from United Kingdom of Great Britain and Northern Ireland, Co-Chair of the Special Interest Group on UN Regulation No. 157 (GRVA-12-36) on the activities of the group. He introduced ECE/TRANS/WP.29/GRVA/2022/3 and ECE/TRANS/WP.29/GRVA/2022/4, aimed at proposing provisions addressing lane change manoeuvres and increasing the maximum design speed of ALKS, up to 130 km/h.

28. The expert from Germany introduced GRVA-12-20. She announced that some discussions were still taking place and that a revised document would be produced in the course of the week. The expert from EC recalled that the document had been discussed by the IWG on EDR/DSSAD and considered by GRSG, as it had been initially drafted as an amendment to UN Regulation No. 160 (EDR). He explained that following discussions, it was advised that the provisions should be inserted in UN Regulation No. 157, and that therefore the document had then been submitted to the Special Interest Group on UN Regulation No. 157. The expert from CLEPA confirmed that the industry did not have issues with the proposal but that a few last-minute clarifying amendments to the document were necessary. The expert from AAPC mentioned that he would circulate the proposal among his members, with the aim to provide feedback, if possible, during the week.

29. Later in the week, GRVA considered a revised document (GRVA-12-20/Rev.1). The expert from the United States of America, Co-Chair of the IWG on EDR/DSSAD, requested the possibility for her group to review the revised proposal, at a meeting taking place one working day after GRVA. Accordingly, GRVA agreed to keep the text contained in the document in square brackets.

30. GRVA reviewed GRVA-12-51 and GRVA-12-51/Rev.1 (note: document not available) prepared during the week and requested the secretariat to submit GRVA-12-52 (based on formal documents ECE/TRANS/WP.29/GRVA/2022/3, ECE/TRANS/WP.29/GRVA/2022/4 and informal documents GRVA-12-34, GRVA-12-35, GRVA-12-20/Rev.1 (including square brackets) to WP.29 and AC.1 for consideration and vote at their June 2022 sessions, subject to final review by GRVA at its May 2022 session.
