24. The expert from ISO informed GRB on the ongoing work in the United States on noise emissions of vehicles in relation with pedestrian safety. He explained that an evaluation of the issue was presently being conducted by the Society of Automotive Engineers (SAE) which included an investigation into possible minimum noise test procedures. In parallel, the US National Highway Traffic Safety Administration (NHTSA) is preparing a research program in order to define the need of requesting a minimum noise level. An SAE report will be concluded by the end of 2008. The expert from ISO offered to inform GRB about the conclusions of the SAE report at its next session.
