5. The expert from Germany recalled the purpose of ECE/TRANS/WP.29/GRSG/2016/20 to improve the accommodation and accessibility for passengers with reduced mobility. He added that GRSG had adopted the document in principle at its previous session as reproduced in GRSG-112-35 subject to the insertion of transitional provisions. Thus, the expert from OICA introduced GRSG-113-15-Rev.1. The expert from Sweden underlined the need to delete the amendments to Annex 8, paragraph 3.2.4. GRSG adopted ECE/TRANS/WP.29/GRSG/2016/20 as reproduced in Annex V to the session report (based on GRSG-113-15-Rev.2) and requested the secretariat to submit it to WP.29 and AC.1 as draft 08 series of amendments to UN Regulation No. 107 for consideration at their March 2018 sessions.

6. The expert from the Czech Republic introduced ECE/TRANS/WP.29/GRSG/2017/14 to improve the safety requirements for trolleybuses, particularly the double insulation of circuits directly connected to the overhead lines. GRSG adopted ECE/TRANS/WP.29/GRSG/2017/14 and requested the secretariat to submit it to WP.29 and AC.1 as draft Supplement 7 to the 06 series of amendments, as draft Supplement 6 to the 07 series of amendments and as part (see para. 5) of draft 08 series of amendments to UN Regulation No. 107 for consideration at their March 2018 sessions.

8. The expert from Germany proposed amendments to UN Regulation No. 107 to improve the accommodation and accessibility for passengers with reduced mobility (ECE/TRANS/WP.29/GRSG/2016/20 and Corr.1) including new testing provisions to ensure visual contrast of some safety elements and the installation of loudspeakers. The expert from Japan introduced GRSG-111-28 on the efforts in his country to set up legal conditions for barrier-free public transport systems. He presented GRSG-111-36 which outlines the specifications for non-step buses. The expert from UITP welcomed all these efforts, but reminded GRSG of the necessity to avoid design restrictions and to limit such provisions only for certain vehicles of category M3. The expert from the United Kingdom endorsed the position. A number of experts were of the opinion that all aspects linked to the environment and health (such as hygienic conditions, colour specifications, visibility and contrast issues) should be regulated on a national/regional level. The expert from Belgium preferred to insert such provisions, if necessary, as only optional requirements.

9. GRSG noted the observations by IRU that the new amendments proposed by Germany might create an additional burden on road transport operators without increasing road safety (GRSG-111-16). The experts from CLCCR and OICA shared these concerns. The Chair invited all experts to send their written comments to the expert from Germany. GRSG agreed to resume consideration, at its next session in April 2017, of ECE/TRANS/WP.29/GRSG/2016/20 as reflected in GRSG-111-35 on the basis of a revised document to be submitted by Germany.
