8. The expert from Germany, Chair of the informal working group on UN GTR No. 9 Phase 2, introduced the terms of references and operating principles (GRSP-50-29) and the first progress report (GRSP-50-30) of the informal working group on UN GTR No. 9 Phase 2. GRSP noted that the main objective of the group should be the introduction of the flexible pedestrian legform (Flex-PLI) into the UN GTR and into the draft UN Regulation on pedestrian safety in the same time. He also asked GRSP experts to provide information on leg injuries to the informal working group. He finally informed GRSP about the intention of the informal working group to submit for consideration, to GRSP a draft proposal at its May 2013 session. GRSP adopted the terms of reference of the informal working group (contained in GRSP-50-29), as reproduced in Annex II to this report and agreed to seek the consent from WP.29 at its March 2012 session. GRSP also agreed to keep ECE/TRANS/WP.29/GRSP/2011/13 on the agenda of its future sessions, awaiting the outcome of the informal working group on UN GTR No. 9 Phase 2.

GRSP agreed to defer discussion on the proposal to introduce the Flex-PLI into the draft UN Regulation (ECE/TRANS/WP.29/GRSP/2011/14) to its May 2012 session awaiting the outcome of the informal working group. Finally, it was agreed to keep ECE/TRANS/WP.29/GRSP/2011/14, ECE/TRANS/WP.29/GRSP/2011/20 on the agenda of future sessions of GRSP.
