标准摘要
[中文适用范围]： 智能交通系统 (ITS) 参考架构是一种描述 ITS 如何提供一项或多项 ITS 服务的工具。 它包括对向利益相关者提供服务所需的主要元素及其相互关联的高级描述。 它提供了一个框架，围绕该框架，可以在 ITS 标准内对接口、规范和详细的 ITS 设计进行标准化。 相比之下，ITS 标准通常侧重于设计细节。 虽然这些标准的开发可能是由单个 ITS 用户需求发起的，但它们通常（并且正确地）以通用格式编写，允许在广泛的环境中应用。 然而，这可能会给读者理解标准的最初目的以及该标准是否适用于其他环境带来挑战。 本文档定义了标准的文档规则，这些标准定义了 ITS 参考架构的系统元素之间的接口。 这包括： a) 记录 ITS 参考架构各方面的要求； b) 记录或引用 ITS 参考架构的各个方面时使用的术语。 在编写本文档时，作者假设使用当代系统工程实践。 本文件中未定义此类做法。 [外文原描述]： An intelligent transport system (ITS) reference architecture is a tool that describes how an ITS delivers one or more ITS services. It includes a high-level description of the major elements and the interconnections among them that are needed for the service(s) to be provided to stakeholders. It provides the framework around which the interfaces, specifications, and detailed ITS designs can be standardized within ITS standards. By contrast, ITS standards are often focused on design details. While the development of these standards may be initiated by a single ITS user need, they are often (and properly) written in a generic format that allows for application in a broad array of contexts. However, this can present a challenge to the reader in understanding the original purpose of a standard and whether the standard is intended for other environments. This document defines documentation rules for standards that define interfaces between or among system elements of an ITS reference architecture. This includes: a) requirements for documenting aspects of the ITS reference architecture; b) terminology to be used when documenting or referencing aspects of the ITS reference architecture. In compiling this document, the authors have assumed that contemporary systems engineering practices are used. Such practices are not defined within this document.
