本文件规定了智能交通系统（ITS）应用和服务地理数据库的概念和逻辑数据模型以及物理编码格式。它包括对此类数据库的潜在内容（特征、属性和关系的数据字典）的规范，对这些内容应如何表示的规范，以及如何指定数据库本身的相关信息（元数据）的规范。 本文件的重点是其应用和服务，并强调道路和道路相关信息。然而，除道路和道路相关信息外，其应用和服务还需要信息。 示例1其应用程序和服务需要有关寻址系统的信息，以便指定位置和/或目的地。因此，有关一个地区的行政和邮政分区的信息至关重要。 示例2地图显示是其应用程序和服务的重要组成部分。为了正确显示地图，必须包含土地和水覆盖等上下文信息。 例3兴趣点（POI）或服务信息是旅行者信息的关键特征。它为最终用户及其应用程序和服务增加了价值。 本文件针对的典型ITS应用和服务包括车辆或便携式导航系统、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。 概念数据模型比其应用程序和服务有更广泛的关注点。它独立于应用程序，允许将来将本文件与其他地理数据库标准进行协调。

This document specifies the conceptual and logical data model and physical encoding formats for geographic databases for Intelligent Transport Systems (ITS) applications and services. It includes a specification of potential contents of such databases (data dictionaries for Features, Attributes and Relationships), a specification of how these contents shall be represented, and of how relevant information about the database itself may be specified (metadata). The focus of this document is on ITS applications and services and it emphasizes road and road-related information. ITS applications and services, however, also require information in addition to road and road-related information. EXAMPLE 1 ITS applications and services need information about addressing systems in order to specify locations and/or destinations. Consequently, information about the administrative and postal subdivisions of an area is essential. EXAMPLE 2 Map display is an important component of ITS applications and services. For proper map display, the inclusion of contextual information such as land and water cover is essential. EXAMPLE 3 Point-of-Interest (POI) or service information is a key feature of traveller information. It adds value to end-user ITS applications and services. 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 has a broader focus than ITS applications and services. It is application independent, allowing for future harmonization of this document with other geographic database standards.
