标准范围

本文件规定了不同智能交通系统（ITS）服务在其站点（ITS-S）之间交换信息所需的车内信息（IVI）数据结构。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，以容纳当前信息。传输的信息包括IVI，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、基于位置的服务、重新路由。容器中的信息被组织在称为数据帧和数据元素的子结构中，这些子结构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。g、 在实时、短程通信的情况下。

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, location-based 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.
