标准摘要
[中文适用范围]： 本文件提供了国际上定义的主要服务的描述，以促进实现之间的一致性。实现可以结合任何其他适当的服务提供这些服务中的任何一个。本文件通过定义服务组来组织 ITS 服务，这些服务组被放置在几个服务域之一中。每个服务组包含一个或多个单独的服务，每个服务都有描述。本文件旨在供参与 ITS 部门的至少两组人使用：a) 那些正在寻找有关 ITS 实现可以提供的服务的想法的人，以及 b) 那些正在制定国际标准的人。对于第一组，本文件提供了可以作为更详细描述的催化剂的服务描述。详细程度可能因 ITS 实现而异，具体取决于是否涉及国家 ITS 架构，以及该架构是否直接基于服务或功能组。本文件中的服务描述处于高层次，因为过多的细节可能会变得规范化并降低灵活性。对于标准制定者，本文件适用于为 ITS 领域制定国际标准的技术委员会。本文件旨在提供可作为制定标准的基础和理由的服务的信息和解释。由于其性质，本文件主要是建议性和信息性的，要求很少。它旨在帮助将服务集成到一个有凝聚力的参考架构中，从而促进互操作性和通用数据定义的使用。具体而言，服务组中定义的服务可以作为定义“用例”、“用户需求”或“用户服务要求”的基础，具体取决于用于开发最终 ITS 架构功能的方法。它们还可以帮助定义数据字典中的适用数据以及适用的通信和数据交换标准。 [外文原描述]： This document provides a description of the primary services that have been internationally defined to promote consistency among implementations. Implementations can provide any of these services in combination with any other services that are appropriate. This document organizes ITS services by defining service groups, which are placed into one of several service domains. Each service group contains one or more individual services, each of which is described. This document is intended for use by at least two groups of people involved in the ITS sector: a) those who are looking for ideas about the services that ITS implementations can provide, and b) those who are developing International Standards. For the first group, this document provides service descriptions that can act as the catalyst for more detailed descriptions. The level of detail can differ from one ITS implementation to another, depending on whether or not a national ITS architecture is involved, and whether or not this architecture is based directly on services, or on groups of functions. The service descriptions in this document are pitched at a high-level as too much detail can be prescriptive and reduces flexibility. For standards developers, this document is applicable to Technical Committees who are developing International Standards for the ITS sector. This document is designed to provide information and explanations of services that can form the basis and reason for developing standards. Due to its nature, this document is largely advisory and informative with minimal requirements. It is designed to assist the integration of services into a cohesive reference architecture, thereby promoting interoperability and the use of common data definitions. Specifically, services defined within the service groups can be the basis for defining “use cases”, “user needs” or "user service requirements” depending on the methodology being used to develop the resultant ITS architecture functionality. They can also assist with defining applicable data within data dictionaries, and applicable communications and data exchange standards.
