19. The expert from the United Kingdom of Great Britain and Northern Ireland introduced the report of the Special Interest Group on UN Regulation No. 157, provided in GRVA-09-22. He recalled the matters that the group was willing to address. He announced the ambition of the group to meet on a monthly basis and to complete its activities until September 2021. He also mentioned the workshop organized by the industry that discussed emergency vehicles and vehicle categories. GRVA agreed to keep ECE/TRANS/WP.29/GRVA/2020/32 and ECE/TRANS/WP.29/GRVA/2020/33 as well as ECE/TRANS/WP.29/GRVA/2021/2 and ECE/TRANS/WP.29/GRVA/2021/4 on the agenda for reference.
20. The expert from USA explained that in his opinion, there were two distinct activities. On one hand, activities related to scope extension to additional vehicle categories, speed increase and lane change for emergency situations. On the other hand, so called convenience lane changes that would fall in the remit of FRAV activities.
21. The expert from Japan supported the ongoing activities. He mentioned that the timeline was ambitious and would have to be adjusted as necessary to allow sufficient time for technical discussions and satisfactory coordination with the IWGs on FRAV and VMAD.
22. The expert from France fully supported the ongoing activities. He also noted that the timeline was ambitious but felt that it was necessary. He mentioned that the group did not discuss some important technical details such as speeds, accelerations, decelerations and the tyre performance. He explained that tyres were replaced in the lifetime of the vehicle and that the performance of tyre could vary, also in case of winter tyres installation, which has to be addressed as a safety risk. He wrote in the messaging system of the meeting that the IWG on FRAV could address this issue.
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.
