标准摘要
[中文适用范围]： 除了智能交通系统（ITS）应用程序和服务的地理数据库的物理编码格式之外，本文档还指定了概念和逻辑数据模型。 该文档包括此类数据库的潜在内容的规范（特征、属性和关系的数据字典）、如何表示这些内容的规范以及如何指定有关数据库本身的相关信息（元数据）。 该文件进一步定义了自动驾驶系统、协作式 ITS 和多式联运中使用的地图数据。 本文件的重点首先是新兴的ITS应用和服务，例如CooperativeITS和自动驾驶系统，并强调道路、车道以及道路和车道的相关信息。 然而，ITS应用和服务除了道路和道路相关信息外，还需要其他信息，这些信息作为外部数据库提供，与GDF连接并相互补充。 例如，高度定义的公共交通数据库在多式联运应用和服务中尤其不可或缺。 因此，本文档的第二个重点是扩展规范以连接外部现有数据库。 它专为连接符合 Transmodel（EN 12896-1 和 EN 12896-2）标准的公共交通数据库而设计。 本文件针对的典型 ITS 应用和服务是车载或便携式导航系统、交通管理中心或与道路管理系统（包括公共交通系统）相关的服务。 这里指定的概念数据模型比 ITS 应用程序和服务具有更广泛的关注点。 它独立于应用程序，允许未来将该模型与其他地理数据库标准协调一致。 [外文原描述]： This document specifies the conceptual and logical data model in addition to the physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. This document includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents are to be represented, and how relevant information about the database itself can be specified (metadata). This document further defines map data used in automated driving systems, Cooperative-ITS, and Multi-modal transport. The focus of this document is firstly on emerging ITS applications and services, such as Cooperative-ITS and automated driving systems, and it emphasizes road, lane and relevant information on road and lane. However, ITS applications and services also require other information in addition to road and road-related information, which are provided as external databases to connect with GDF and to complement each other. Highly defined public transport databases, for instance, are indispensable in multi-modal transport applications and services in particular. Thus, this document focuses secondly on an expansion of the specification to connect with externally existing databases. It is particularly designed to connect a Transmodel (EN 12896-1 and EN 12896-2) conformant public transport database. Typical ITS applications and services targeted by this document are in-vehicle or portable navigation systems, traffic management centres, or services linked with road management systems, including public transport systems. The conceptual data model specified here has a broader focus than ITS applications and services. It is application independent, allowing for future harmonization of this model with other geographic database standards.
