21. The expert from Germany proposed to correct the provisions of paragraph 16.1.3.1. on the magnification factor (GRSG-111-27). GRSG supported the proposal in principle and agreed to resume consideration of this subject at its next session in April 2017. For that purpose, the secretariat was requested to circulate GRSG-111-27 with an official symbol.

19. On behalf of the Task Force on UN Regulation No. 46, the expert from Japan reported on the progress made by the group during its meeting in Paris on 26-27 September 2016 (GRSG-111-22). He introduced GRSG-111-23 (superseding GRSG-110-12) proposing amendments to UN Regulation No. 46. GRSG welcomed the important work done by the Task Force led by Japan. To broaden the participation of other Contracting Parties in the discussions on this subject, GRSG agreed to set up a new Informal Working Group (IWG) on close proximity vision and obstacle detection systems. GRSG noted a first draft of the terms of reference and rules of procedure for the IWG (GRSG-111-29) and agreed to formally adopt them at its next session.

20. The GRSG Chair announced his intention to seek the consent of WP.29 at its November 2016 session to establish the above-mentioned IWG. GRSG referred GRSG-111-23 and GRSG-111-29 to the IWG for further consideration and invited the Group to take into account all relevant studies published world-wide on this subject.
