本文件规定了不同行业所需的车内信息（IVI）数据结构 智能交通系统（ITS）为站点之间的信息交换提供服务。 指定了一个通用的、可扩展的数据结构，将其拆分为称为容器的结构，以 容纳当日信息。传输的信息包括IVI，例如上下文 速度、道路工程警告、车辆限制、车道限制、道路危险警告、基于位置 服务，改道。容器中的信息以子容器的形式组织- 称为数据的结构 框架和数据元素，根据其内容和语法进行描述。 数据结构被指定为通信不可知。本文件不提供 通信协议。本文档提供了数据结构的使用场景，例如 实时短程通信。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies the in-vehicle information (IVI) data structures that are required by different intelligent transport system (ITS) services for exchanging information between ITS Stations (ITS-S). A general, extensible data structure is specified, which is split into structures called containers to accommodate current-day information. Transmitted information includes IVI such as contextual speed, road works warnings, vehicle restrictions, lane restrictions, road hazard warnings, locationbased services, re-routing. The information in the containers is organized in sub-structures called data frames and data elements, which are described in terms of its content and its syntax. The data structures are specified as communications agnostic. This document does not provide the communication protocols. This document provides scenarios for usage of the data structure, e.g. in case of real time, short-range communications.All current amendments available at time of purchase are included with the purchase of this document.
