T/ITS 0118-2020 Cooperative Intelligent Transportation System (CITS) - Application Layer and Interaction Standards for Vehicle-to-Vehicle (V2V) Communication Systems in Stage 2

Scope

Main technical content: The T/ITS 0058-2017 standard completes the definition of 17 basic application scenarios and corresponding interaction message sets. We call this the "first phase" of the series of standards titled "Cooperative Intelligent Transportation System - Vehicle Communication System Application Layer and Application Data Interaction Standards". On the basis of this standard, after industry validation and improvement, the YD/T 3709-2020 standard titled "LTE-based Internet of Vehicles Wireless Communication Technology - Message Layer Technical Requirements" was formulated, enhancing China's LTE-V2X standard system. In response to the evolution of vehicle communication technology and new demands for cooperative vehicle-road applications, this document further develops the second phase of application scenarios under the framework of the "Cooperative Intelligent Transportation System - Vehicle Communication System Application Layer and Application Data Interaction Standards" series of standards, including scenario description, implementation process, communication methods, basic performance requirements, and data interaction needs; and, on the basis of the first phase message sets, supplements and expands compatibility to new messages, capable of simultaneously supporting all applications of both phases. In terms of communication methods, the first phase message interactions all use broadcast mode, meaning that messages are sent without specific receiving objects, and all traffic participants within the communication range can receive corresponding messages. However, the second phase message interactions not only include broadcast mechanisms, but also support information interaction methods and processes with specific receiving objects (one or more), namely using multicast or unicast communication methods. This document specifies the second phase application scenarios and corresponding interaction data technical requirements of the application layer of the
