9. The expert from Sweden, chairing the informal group on Automated Connections between Vehicles (ACV), reported on the progress made by the group (GRRF-73-09). The informal group produced the informal document GRRF-73-15 proposing to amend UN Regulation No. 13 with provisions for Automated Connections between Vehicles. Following a discussion on the interoperability and safety provided by such systems, GRRF requested the informal group to provide some clarifications and a risk analysis for consideration at the next session of GRRF.

10. The expert from Sweden sought GRRF’s guidance on the part of the mandate of ACV informal group with respect to road trains. Some governmental experts expressed their wish to work on this matter. The expert from CLEPA reminded GRRF about the existence of GRRF-66-08. This document will be reinserted into the agenda of the next session of GRRF. At the request of the informal group, the chair provided guidance on the prioritization of work, proposing to finish the work on ACV and then to start to work on road trains. In this respect, the chair requested the informal group to review the terms of reference of ACV and to prepare an updated version if necessary.
