This document is applicable to RS-LSADS in vehicles that provide passenger transport or logistics services on predefined routes. This document specifies: —     the terms and definitions related to RS-LSADS and the system architecture of RS-LSADS; —     functions of RS-LSADS, which are: remote monitoring, remote assistance and remote driving that is operated under very limited conditions, and conditions under which they need to be activated; —     the performance requirements, system requirements and performance test procedures of RS-LSADS; —     the data to be communicated between vehicles and the remote support facility (but not protocols or other aspects of communication system).
