道路几何和属性定义™ ASN 文件的最低要求

[中文适用范围]： SAE J2945/A 和此抽象语法符号 (ASN.1) 文件精确定义了用于实现符合推荐实践的应用程序的数据结构。使用 ASN.1 规范，编译器工具可用于使用 J2945/A 中标识的编码规则生成编码。该 ASN.1 文件和 SAE J2735 ASN.1 文件都是共同实现 J2945/A 中描述的数据结构所必需的。任何接收应用程序（以及应用程序的附加逻辑）都可以使用组合库。 SAE J2945/A 还为发送和接收道路几何和属性 (RGA) 消息的接口提供了建议。它提供了构建依赖 RGA 消息的可互操作应用程序所需的信息。 [外文原描述]： SAE J2945/A and this Abstract Syntax Notation (ASN.1) file precisely define the structure of the data used to implement applications conformant to the Recommended Practice. Using the ASN.1 specification, a compiler tool can be used to produce encodings using encoding rules identified in J2945/A. Both this ASN.1 file and the SAE J2735 ASN.1 files are necessary to collectively implement the data structures described in the J2945/A. The combined library can be used by any receiving application (along with the additional logic of the application). SAE J2945/A also provides recommendations for the interface for sending and receiving Road Geometry and Attributes (RGA) messages. It provides the information necessary to build interoperable applications that rely on RGA messages.
