Global Technical Regulation No. 9
Pedestrian Safety

Proposal to ensure pedestrian safety across the vehicle height variations that may be produced by active suspensions.

8. The expert from Germany introduced GRSP-65-17, explaining that the intention of the pedestrian protection test procedures as described in UN GTR No. 9 and UN Regulation No. 127 was to deliver an adequate level of protection for pedestrians in accidents up to an impact velocity of 40 km/h. International Harmonized Research Agenda research has shown that the cumulative frequency curves versus vehicle impact speed for pedestrian injuries and their respective injury causing parts showed that 58 per cent of the child head abbreviated injury scale (AIS) 2+ injuries were addressed to a vehicle impact speed up to 40 km/h, 40 per cent to adult head AIS2+ injuries and 50 per cent of the adult leg AIS2+ injuries respectively. He added that test procedures described in UN Regulation No. 127 and UN GTR No. 9 were meant to represent worst case scenarios. However, it was agreed that this was not the case for all possible scenarios and that also at lower impact speeds higher injury risk could occur due for example to different heights of the vehicle because of adjustable suspension systems. The representative from OICA reminded that during the type approval process the worst case scenario will be considered. GRSP agreed to keep GRSP-65-17 as an informal document for the December 2019 session of GRSP, awaiting further rationales to develop a proposal of amendments.

7. The expert from Germany, on behalf of the Chair of the pedestrian safety IWG, introduced the amendment to M.R.1 for the new Addendum 3 to M.R.1 (ECE/TRANS/WP.29/GRSP/2019/4), incorporating drawings, specifications and the manual of the Flex Pedestrian Legform Impactor (FlexPLI): GRSP-65-01 and GRSP-65-02. The experts from France and the Russian Federation confirmed that the manual and technical specifications should not be translated. However, it was noted that GRSP-65-01 and GRSP-65-02 would not be displayed on the WP.29 website until a disclaimer letter would be provided (see para. 4). Finally, GRSP adopted ECE/TRANS/WP.29/GRSP/2019/4 unamended. The secretariat was requested to submit the proposal as Amendment 2 to M.R.1 for consideration and vote at the November 2019 sessions of WP.29 and AC.3.

42. Discussion was concluded under agenda items 2, 3(a) and 5 (see paras. 4, 7 and 13).
