Document presents development of traumatic brain injury risk functions for frontal crash assessment. Brain strain-based injury risk functions were developed using human and non-human primate injury data from experimental studies, calculated using finite element brain models. Kinematics-based injury risk functions were derived by converting strain-based functions using correlations with head rotational kinematics metrics. Injury risk functions were developed for each kinematics-based metric selected through correlation analysis with maximum principal strain in brain tissue.
Status report on the 1998 Agreement global registry and compendium of candidates as of 13 November 2026. The document presents the current state of play for multiple UN GTRs across working parties GRVA, GRSP, GRPE, GRBP, and GRSG, including informal groups, technical sponsors, formal proposals, and draft UN GTR proposals. It details progress on items such as Automated Driving Systems, Electric Vehicle Safety, Equitable Occupant Protection, and various amendments to existing GTRs, with notes on AC.3 endorsements and adoption dates.
Report of the 57th session of the IWG on DETA held on 13 November 2026. The session covered the state of play with 153,000 approvals uploaded by 23 approval authorities, a new DETA software version introducing two-factor authentication and internal mail functionality with migration expected Q1/2027, widening the scope to include a scenario database for automated driving and potential use for sharing technical information on brake emission of non-original parts, amendments to guidelines for UNR155 reflecting changes to the new software version, and plans for a joint IWVTA/DETA workshop on 24 June 2027.
