道路几何形状和属性定义的最低要求

[中文适用范围]： 本报告规定了道路几何和属性 (RGA) 数据集 (DS) 的最低要求，以支持与道路几何相关的机动车辆安全应用。本报告包含使用详细的系统工程流程开发的操作、需求和设计概念。利用这些要求，定义了 RGA DS，其中包括 DS 抽象语法符号一 (ASN.1) 格式、数据帧和数据元素定义。这些要求旨在实现消息及其 DS 信息的交换，以提供所需的互操作性和数据完整性，以支持本报告中考虑的应用程序以及可能能够利用 DS 信息的其他应用程序。除此之外的系统要求不在本报告的讨论范围之内。 [外文原描述]： This report specifies the minimum requirements for the Road Geometry and Attributes (RGA) data set (DS) to support road geometry related motor vehicle safety applications. Contained in this report are a concept of operations, requirements, and design, developed using a detailed systems engineering process. Utilizing the requirements, the RGA DS is defined, which includes the DS Abstract Syntax Notation One (ASN.1) format, data frames, and data element definitions. The requirements are intended to enable the exchange of the messages and their DS information to provide the desired interoperability and data integrity to support the applications considered within this report, as well as other applications which may be able to utilize the DS information. System requirements beyond this are outside the scope of this report.
