20. GRB noted that the draft Regulation on quiet road transport vehicles (QRTV) (ECE/TRANS/WP.29/2016/26) had been adopted by WP.29 and AC.1 at their March 2016 sessions and would enter into force as Regulation No. 138 in October 2016 (Depository Notification C.N.125.2016.TREATIES-XI.B.16 of 5 April 2016).

21. The expert from EC briefed GRB on how the technical and administrative provisions of Regulation No. 138 on the Acoustic Vehicle Alerting System (AVAS) requirements would be incorporated in Annex VIII to EU Regulation No. 540/2014 (GRB-64-19).

22. The experts from Japan and OICA proposed an editorial change as well as further amendments to Regulation No. 138 to prohibit the pause function for AVAS (ECE/TRANS/WP.29/GRB/2016/8, ECE/TRANS/WP.29/GRB/2016/9 and GRB-64-03). These proposals were supported by the experts of Germany, Italy, Poland, United States of America and WBU. GRB adopted the proposals, as laid down in Annex V, and requested the secretariat to submit them WP.29 and AC.1 for consideration and vote at their March 2017 sessions as a draft Supplement 1 to the original series and a new draft 01 series of amendments to Regulation No. 138.

23. The expert from France, in his capacity of Co-chair of the IWG on a Quiet Road Transport Vehicles (QRTV) Regulation under 1958 Agreement, reported on the status of QRTV-related work (GRB-64-14).

25. The expert from OICA presented the outcome of their survey of owners (drivers) of a specific electric vehicle model on their experiences with AVAS (GRB-64-20 and GRB-64-21). GRB welcomed the study and called for more AVAS surveys, in particular of vulnerable road users (e.g. cyclists, pedestrians, blind or people with impaired vision).

32. The Chair presented a revised list of possible issues for the future GRB activities compiled at the third informal meeting in July 2016 (GRB-64-08). The expert from Japan proposed modifications to the time limits of some activities listed in this document. The expert from France presented proposals to improve efficiency of road vehicle noise Regulations by tackling such issues as day-to-day and track-to-track dispersion between measurements and different interpretations of the same text (GRB-64-15). The expert from EC proposed to include three additional points related to L-category vehicles (GRB-64-17). The expert from OICA reported on a meeting between ETRTO and OICA which concluded that a harmonized test procedure for tyre and vehicle noise measurements would be beneficial for industry and environment. Finally, GRB invited all experts to submit their comments in writing to the Chair and requested the Chair to update the list accordingly.
