标准摘要
[中文适用范围]: 本文档描述并列出了精确相对位置参考方法(PRLRM)的特征,该方法描述了地理数据库上下文中的精确相对位置,并用于在编码器系统以及解码器端定位与传输相关的对象。 本文档没有定义用于实现 PLRRM 的物理格式。 但是,定义了物理格式的要求。 本文件没有定义精确相对位置参考系统(PRLRS)的细节,即如何在软件、硬件或过程中实现PRLRM。 本文件规定了 PLRM,包括: ——位置参考方法(LFM)的概念数据模型; ——精确相关信息的位置参考规范; ——精确相对位置参考的用例(资料性附录 C); ——精确相对位置参考元素的用例(资料性附录 D); ——实施精确相对位置参考(日本示例)(资料性附录 E)。 本文档定义了能够交换车道或车道交叉口中要引用的对象的位置信息的方法。 本文档未指定参考对象所在的道路(路段)。 [外文原描述]: This document describes and lists the characteristics of the Precise Relative Location Referencing Method (PRLRM) which describes precise relative locations in the context of geographic databases and is used to locate transport-related objects in an encoder system as well as in the decoder side. This document does not define a physical format for implementing the PRLRM. However, the requirements for physical formats are defined. This document does not define details of the Precise Relative Location Referencing System (PRLRS), i.e. how the PRLRM is to be implemented in software, hardware or processes. This document specifies PRLRM, comprising: — conceptual data model for Location Referencing Methods (LFMs); — specification of location referencing for precise relative information; — use cases for Precise Relative Location References (informative Annex C); — use cases for elements of Precise Relative Location References (informative Annex D); — implementation of Precise Relative Location References (Japanese example) (informative Annex E). This document defines methods that enable exchange location information of the object to be referenced in the lane or the lane junction. This document does not specify the road (link) on which the object of reference exists.
