10. The expert from Finland introduced GRSP-73-06 to propose a new series of amendments to UN Regulations Nos. 14 and 16 that remove the derogations for the two-point safety belts (GRSP-70-05). He recalled to GRSP that GRSP-70-07, introduced at the seventieth session of GRSP, showed evidence of an insufficient level of safety with two-point belts. He concluded that equipping buses with three-point safety belts was a cost-effective way to increase safety for passengers. The expert from the Netherlands in principle supported the proposal and asked a time reservation. The expert from Italy also requested time reservation. The expert from the United Kingdom informed GRSP of a low number of bus crash casualties in his country. The expert from OICA recalled GRSP-70-06 and GRSP-70-07 that were introduced by the expert from Finland at the seventieth session of GRSP, and requested clearer evidence of the benefit of three-point safety-belts, including for other countries. The expert from Germany also stated a low number of bus casualties in his country; GRSP noted that he would provide further statistics at its December session. The expert from Japan also informed of a low number of bus casualties and noted there was no evidence that three-point belts would be beneficial. GRSP agreed to resume discussion at its December 2023 session based on a revised proposal and requested its experts to provide further statistical data. GRSP noted that if a new replacement proposal was not received by the secretariat, GRSP-73-06 should be confirmed for submission as an official document.

26. GRSP considered GRSP-73-17, (superseding ECE/TRANS/WP.29/GRSP/2023/10) by the expert from the Netherlands, aimed at identifying HDV equipped with an electric drivetrain. He added that the proposal of additional labelling would help emergency services to determine how to approach these vehicles in case of a fire. The expert from Japan agreed in principle with the proposal. He also introduced GRSP-73-49 to supplement it with the labelling of hydrogen- and fuel-cell vehicles, consistent with UN Regulation No. 134. The expert from the United Kingdom questioned the proposed colours of the labelling, which could conflict with those required by the 1968 Vienna Convention on Road Traffic and in national legislations. The expert from the Russian Federation presented GRSP-73-47 that introduced a proposal (GRSP-73-02) to extend the identification of vehicles to categories M and N with an electric drivetrain. He also informed GRSP that the lack of internet accessibility in numerous areas on the territory of his country would not allow viable solutions such as apps to identify electric vehicles. He added that for vehicles immersed in water (e.g. fallen from a bridge), quick response code reading (QR) would not be applicable. The expert from OICA, argued that buses already had numerous labelling and that electric vehicles with a labelling as such would come across as dangerous, creating excessive alarm for the public. The expert from the Netherland, clarified that passenger vehicles (M1) and light duty vehicles were not a priority for labels because they were covered by the Euro New Car Assessment Programme (Euro NCAP). He added that few HDV were electric-power trained, and needed to be identified for emergency services.

27. GRSP agreed to resume discussion at its December 2023 session and invited concerned parties to liaise with the expert from the Netherlands to develop a comprehensive proposal of all point views (including ECE/TRANS/WP.29/GRSP/2023/10, GRSP-73-17 and GRSP-73-49). The expert from the Russian Federation withdrew GRSP-73-02 and announced a new proposal for the next session.

32. New information was not provided.

33. As per paragraph 16, the expert from the Netherlands on behalf of the Ad Hoc Group on CRS introduced ECE/TRANS/WP.29/GRSP/2023/13 and GRSP-73-18-Rev.2 on allowing the use of LTA. GRSP noted that the additional sentence in paragraph 6.6.4.1.2.1., that clarifies how ISOFIX ECRS should be dynamically tested, was removed from GRSP-73-18-Rev.2. This would allow the new 04 series of amendments to UN Regulation No. 129 proposed in GRSP-73-18-Rev.2 to focus on provisions for Enhanced Child Restraint Systems (ECRS) with lower tethers. GRSP agreed with the principle of the sentence on ISOFIX ECRS, to clarify that an ISOFIX ECRS that relies on the vehicle seat as the sole anti-rotation device must be dynamically tested on each vehicle body shell specified on the CRS fitting list. However, GRSP noted that another amendment of paragraph 6.6.4.1.2. had been proposed by the expert from CLEPA in GRSP-73-42, and so agreed to resume discussion at its December 2023 session. GRSP also adopted ECE/TRANS/WP.29/GRSP/2023/13 as amended by annex VIII to the session report. The secretariat was requested to submit the proposal as draft 04 Series of Amendments to UN Regulation No. 129 to the November 2023 sessions of WP.29 and AC.1. The secretariat was also requested to distribute GRSP-73-42 with an official symbol at its next session. GRSP requested its experts to provide comments on GRSP-73-42 to the expert from CLEPA.

34. The expert from the Netherlands, on behalf of the Technical Services Group, introduced ECE/TRANS/WP.29/GRSP/2023/11 and GRSP-73-14-Rev.1 amending it, to clarify the single belt route principle in paragraph 3.2.2. of the UN Regulation. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/11 as amended by annex VIII to the session report, and requested the secretariat to submit it as draft Supplement 10 to the 03 Series of Amendments and as part of (paragraph 33) the draft 04 series of amendments to UN Regulation No. 129 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

GRSP-73-14/Rev.1 | UN R129: Proposal for Supplement 10 to the 03 Series of Amendments The proposed amendment does not intend to change the requirements nor the level of stringency. The footnote to paragraph 3.2.2. is added to further clarify the definition of the use of a one belt route. In its current state, the text apparently has been interpreted as to allow the use of a single belt route for each application that an Enhanced Child Restraint System (ECRS) would offer. That way, one belt route for a rearward facing ECRS (integral) and a second belt route for a forward facing (non- integral) ECRS has been introduced, making a combination of C and E.

GRSP/2023/11 | UN R129: Proposal for Supplement 10 to the 03 series of amendments Proposal to clarify the single belt route principle mentioned in paragraph 3.2.2.

35. GRSP considered ECE/TRANS/WP.29/GRSP/2023/14 on prevention of green indicators suggesting a belt route outside the remit of the type-approval. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/14, as amended below, and requested the secretariat to submit the proposal as part of (paragraphs 33 and 34 above) draft Supplement 10 to the 03 series of amendments and to include it into (paragraphs 33 and 34) the draft 04 Series of Amendments to UN Regulation No. 129 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

The title, amend to read:
“Proposal for Supplement 10 to 03 Series of Amendments and 04 Series of Amendments to UN Regulation No. 129 (Enhanced Child Restraint Systems)” **

** Note by the secretariat: The change of the title was agreed with the author of the proposal to include the text of the draft Supplement 10 to the 03 Series of Amendments into the draft 04 Series of Amendments to UN Regulation No. 129.

GRSP/2023/14 | UN R129: Proposal for Supplement 10 to the 03 series of amendments Proposal to restrict use of the colour green exclusively to the marking belt route indicators.

36. The expert from France introduced GRSP-73-53 amending the UN Regulation to allow installation of a headrest on the bench in the dynamic frontal test of a universal booster cushion with a Q10 dummy. She clarified that this would allow testing of the universal booster cushion, without damaging the neck of the dummy. GRSP agreed to resume discussion based on a proposal submitted by the expert from France.

39. New information was not provided.

40. As per paragraphs 23, 25 and 38, the expert from OICA introduced GRSP-73-30 (superseding ECE/TRANS/WP.29/GRSP/2023/20) to incorporate provisions on hydrogen- fuelled vehicles into UN Regulation No. 137. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/20 as amended by annex X to the session report. The secretariat was requested to submit the proposal as draft 03 Series of Amendments to UN Regulation No. 137 for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

41. The expert from Japan reiterated GRSP-73-27 on amending the requirement of the Thorax Compression Criterion (ThCC) of the 5th female dummy in vehicles of category N₁ with a maximum permissible mass not exceeding 2,800 kg. He provided the crash data evidence as requested at the December 2022 session of GRSP showing that elderly female passengers require protection in Japan when travelling in the front seats of N1 vehicles. He announced an official proposal for the December 2023 session of GRSP that incorporates the protection of elderly people into N1 vehicles, which currently apply only to M₁. The expert from the Republic of Korea expressed a time reservation to allow investigation at the national level. The expert from France suggested national data comparisons for the December 2023 session of GRSP. The expert from the Netherlands suggested that motorhomes could also be included. The expert from OICA expressed a study reservation arguing that the issue was limited to Japan and suggested consideration of different markets. The expert from Austria stated that Japan was advanced in considering this issue. She also informed GRSP that the IWG on Equitable Protection of Occupants (EqOP) already considered the contribution of Japan for its future work. GRSP agreed to resume discussion at its December 2023 session based on an official proposal submitted by the expert from Japan. Meanwhile, GRSP requested its experts to provide national crash data to justify the proposal to Mr. Yoshinori TANAKA (NTSEL Japan, y-tanaka@ntsel.go.jp) and to Ms. Kazumi WATANABE (JASIC secretariat, watanabe@jasic.org).

42. The expert from OICA introduced GRSP-73-25-Rev.1, aimed at amending the provisions for the number of ISOFIX positions if a built-in CRS is installed in that position. He added that the provision would be adapted to height stature according to UN Regulation No. 129 instead of the superseded mass group of UN Regulation No. 44. GRSP adopted the proposal as reproduced in annex XI to the session report. The secretariat was requested to submit the proposal as draft Supplement 3 to the Original Version of UN Regulation No. 145, for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

GRSP-73-25/Rev.1 | UN R145: Proposal for Supplement 3 Proposal to reflect the size ranges used in UN R129, OICA suggests using the stature of 100 cm (which is approximately a child weighing 18 kg). This would be aligned with the requirement that non-integral ECRS are not allowed for children with a stature of less than 100 cm (6.1.3.3.) and also with the requirement for toxicity testing in 6.3.1.1 (para 6.3.1.1 does not apply to non-integral ECRS with a stature range of 100 cm or above).

43. As per paragraphs 16 and 33, the expert from the Netherlands on behalf of the Ad Hoc Group on CRS introduced ECE/TRANS/WP.29/GRSP/2023/12 and GRSP-73-19-Rev.2, to allow use of LTA. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/12 as amended by annex XI to the session report. The secretariat was requested to submit the proposal as draft 01 Series of Amendments to UN Regulation No. 145, for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

45. As per paragraph 4, the experts from Austria and the Republic of Korea, on behalf of IWG, explained that validation of a reference of Human Body Models (HBM) was relevant for the evaluation of HIT (GRSP-73-03). She noted that validation consisted of simulations of HBM against a model representing a GVM frontend. She clarified that the procedure of validation of HBM was limited to pedestrian HIT. GRSP noted that two proposals of addendum to the Mutual Resolution No.1 (M.R.1) were submitted by the IWG to calculate HIT: (a) Addendum 5 on provisions for the DPPS GVM (ECE/TRANS/WP.29/GRSP/2023/7 as amended by GRSP-73-10-Rev.1); and (b) Addendum 6 on developing HBM qualification corridors (GRSP-73-11). GRSP noted that the development of the two Addenda needed further study and agreed to resume discussion at its December 2023 session.

48. The expert from Spain, Chair of IWG on safer transport of children in buses and coaches informed GRSP about GRSP-73-01 on developing the new UN Regulation. She confirmed that the Group had finalized the first phase on the use of ECRS approved according to UN Regulation No. 129 with three-point safety-belts and/or ISOFIX built-in systems. In Phase 2, she added that IWG would assess ECRS in combination with two-point belts. She added that the terms of references of Phase 2 of IWG would be prepared for comments from the Working Party on General Safety Provisions (GRSG), then for official adoption by GRSP at its December 2023 session. She then introduced GRSP-73-04-Rev.1, superseding ECE/TRANS/WP.29/GRSP/2023/2.

49. GRSP adopted ECE/TRANS/WP.29/GRSP/2023/2, as amended by GRSP-73-04-Rev.1. The secretariat was requested to submit the proposal as a draft new UN Regulation Concerning the Approval of Child Restraint Systems for Safer Transport of Children in Buses and Coaches for consideration and vote at the November 2023 sessions of WP.29 and AC.1.

50. The expert from Germany introduced GRSP-73-57 on the outcome of the Task Force on Autonomous Vehicles Regulatory Screening (TF AVRS) work. He explained that some of the findings can be solved by rewording UN Regulations under GRSP responsibility (e.g. references to “driver”, “steering control”, “Driver R-Point”). He added that some functions (e.g. tell-tales) and some situations like the transport of children on buses without a driver would need discussion in WP.29.

51. GRSP considered GRSP-73-57 to be final and agreed that the coordinated conclusions on TF AVRS in each Working Party be provided to the June 2023 session of WP.29.

GRSP-73-57 | TF AVRS: Status Report

52. GRSP noted the decisions of the Inland Transport Committee (ITC) on climate change and confirmed its support for the development of an ambitious ITC strategy on the reduction of greenhouse gas emissions in inland transport until 2050, with priority actions for the ITC and its subsidiary bodies, and supported by a strong action plan with milestones. It took note of the draft outline (GRSP-73-61). Noting that the deadline for contributions and comments on the draft was Friday, 29 September 2023, GRSP invited delegations to send their contributions to the Chair before the beginning of September on (a) the ITC climate change mitigation strategy until 2050: reflections and considerations as to contributions and ambitious actions with milestones GRSP can make, (b) contributions by GRSP to the in-depth report on climate change and inland transport for the ITC’s eighty-sixth session, on the basis of the preliminary work contained in ECE/TRANS/2023/21.

53. New information was not provided.

54. The expert from Japan, Ambassador of IWVTA, informed GRSP that IWG was developing the 06 series of amendments to UN Regulation No. 0. He noted that this new series reflected the latest series of amendments to UN Regulations Nos. 12, 127 and 135, which had entered into force in January 2023. He added that the proposal would be submitted for approval to the June session of WP.29 after a review by the Technical Secretary of the Group. He reminded GRSP about GRSP-72-07-Rev.1 on interpreting the preceding series of amendments (singular or plural) mentioned in the transitional provisions of UN Regulations. He informed GRSP that no objection to the document had been received from experts, as requested at the December 2022 session of GRSP. He concluded that the document would be reviewed by the June 2023 session of WP.29.

55. GRSP resumed discussion on UI marking. The expert from CITA introduced GRSP-73-58 (based on WP.29-188-20) listing all UN Regulations under GRSP purview and providing information that his organization deems relevant. He added that, in his opinion, none of the UN Regulations under GRSP needed UI. The expert from Germany stated that benefits would not be introduced by UI. The expert from Spain suggested that amending the 1958 Agreement would be more viable than amending each UN Regulations to prohibit UI. GRSP agreed to discuss its final position at its December 2023 session.

56. The Secretary reported (GRSP-73-21) on the 189th session (ECE/TRANS/WP.29/1171).

GRSP-73-21 | Highlights of the March 2023 session of WP.29

57. The expert from the Netherlands introduced the status report of the Ad Hoc Group on the 3D HPM. He informed GRSP that the Group had agreed that the first step would be update the Consolidated Resolution on the Construction of Vehicles (R.E.3) according to the standard J826 of November 2008, of the Society of Automotive Engineers. He announced an informal proposal of amendments to R.E.3. and to the UN Regulations for the October and December 2023 sessions of GRSG and GRSP. GRSP also noted that some UN GTRs should be updated and that placing specifications for 3D HPM into M.R.1 would be the easiest solution to update them. GRSP agreed to resume discussion at its December 2023 session.

58. New information was not provided.

59. The expert from the Republic of Korea sensitized GRSP on this issue. He stated that GRSP was the most suitable group of experts to draft a solution for cars and buses. The expert from Australia reiterated this message and added that the loss of children was not economically quantifiable and urged a solution. The expert from Germany reminded GRSP about Euro NCAP protocols on this subject. GRSP agreed continue gathering global information and statistics for its next sessions as a first step.

60. The expert from Norway introduced GRSP-73-22, showing statistical evidence that a considerable number of accidents involved buses wherein the drivers had been seriously injured or killed in head-on collisions in Norway. The expert from the United Kingdom stated a lack of statistics from his country for this activity. The expert from the Netherlands suggested that GRSP was the correct body to address this issue although merit needed to be verified. He also suggested considering UN Regulation No. 66 (Strength of superstructure (buses)) under the responsibility of GRSP to have a thorough approach to passive safety. The expert from Finland agreed with the concerns in GRSP-73-22 and added that the steering wheel function should be also investigated. GRSP agreed to resume discussion at its December 2023 session and requested experts to provide statistical data at that session.

GRSP-73-22 | UN R29: Discussion on Frontal protection in buses Discussion on the introduction of technical requirements applying to the bus front to reduce the extent of damage and injury in connection with potential frontal impact accidents. It has also been raised by the labour unions that buses need to become more crash resistant. Plan is to change the scope and perhaps add a new section for testing the front of the buses. Alternatively make a new regulation for frontal protection for buses.

61. The seventy-fourth session of GRSP was scheduled for Geneva from 4 (2.30 p.m.) to 8 December (12.30 p.m.) 2023. GRSP noted the twelve-week deadline for the submission of official documents to the secretariat as 11 September 2023.
