40. The expert from GTB introduced a brainstorming paper on signalling requirements for automated/autonomous vehicles (AVs) (GRE-80-16-Rev.1). The secretariat also informed GRE about the establishment, at the June 2018 session of WP.29, of a new Working Party “Groupe de Rapporteurs pour les Véhicules Autonomes” (GRVA) and that coordination between GRVA and other WP.29 Working Parties (GRs) would be done at the WP.29 level. GRE discussed at length how to pursue considering the signalling requirements for AVs, and came to a conclusion that a task force (TF) would be most appropriate for this purpose. The expert from Germany, who was leading TF SR, also agreed to take the lead in the new TF. The experts from UK, GTB and OICA expressed their support to TF. GRE agreed that TF should evaluate and report on the safety needs for AVs to signal their status and communicate their next intended actions using visual or audible signals or a combination of both.
