支持交通信号优先和抢占™ SET文件的最低要求

[中文适用范围]： 本套资料包含SAE J2945/B标准，该标准规定了联网车辆（CVs）与联网交叉口（CIs）之间用于支持交通信号优先和抢占（TSPP）应用的空中下载（OTA）接口。标准中规定了使用更新版本的SAE J2735信号请求消息（SRM）和信号状态消息（SSM），并使用车辆环境中无线接入（WAVE）服务通告（WSA）以宣传CIs对TSPP的支持。本套资料还包括操作概念、需求、设计、抽象语法符号一（ASN.1）消息格式、数据帧和数据元素的定义。此外，ASN.1文件还精确地定义了用于实现符合SAE J2945/B标准的应用的数据结构。使用该ASN.1规范，可以使用编译器工具生成编码，以便应用程序轻松对信号请求消息（SRM）和信号状态消息（SSM）消息以及定义在SAE J2945/B中的WAVE服务通告（WSA）应用数据进行编码和解码。ASN.1文件中包含完整的SAE J2735 ASN.1规范，以及SAE J2945/B中对SRM和SSM的ASN.1定义的更新内容。 [外文原描述]： Included in this set are the SAE J2945/B Standard which specifies the over-the-air (OTA) interface between connected vehicles (CVs) and connected intersections (CIs) to support traffic signal priority and preemption (TSPP) applications. It specifies the use of updated revisions of the SAE J2735 Signal Request Message (SRM) and Signal Status Message (SSM) and the use of a Wireless Access in Vehicular Environments (WAVE) Service Advertisement (WSA) to advertise support for TSPP at a CI. Included are a concept of operations, requirements, design, and the Abstract Syntax Notation One (ASN.1) message format, data frame, and data element definitions.Also included is the Abstract Syntax Notation One (ASN.1) file precisely defines the structure of the data used to implement applications conformant to the SAE J2945/B Standard. Using this ASN.1 specification, a compiler tool can be used to produce encodings to enable applications to easily encode and decode the Signal Request Message (SRM) and Signal Status Message (SSM) messages, along with the Wireless Access in Vehicular Environments (WAVE) Service Advertisement (WSA) application data, defined in SAE J2945/B defined in SAE J2945/B. Included in the ASN.1 file is the complete SAE J2735 ASN.1 along with the updates to the ASN.1 for the SRM and SSM defined in SAE J2945/B.
