Minimum Requirements for Road Geometry and Attributes Definition

2024-05-17
WIP
J2945/A
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. NOTE: Unless otherwise marked as Informative, all material in this report is to be considered normative.

Minimum Requirements for Road Geometry and Attributes Definition™ ASN File

CURRENT
J2945/AA_202404
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.

J2945/1B
This SAE Standard specifies the system requirements for vehicle-to-vehicle (V2V) safety system for FHWA vehicle classes 1 (motorcycles and 4 through 13 (non-light-duty), including functional requirements and performance requirements. The system can transmit and receive the SAE J2735-defined Basic Safety Message (BSM) over a wireless communications interface; the communications interface itself is outside the scope of this document. This document provides the specifications necessary to build interoperable systems that support V2V safety applications for non-lightweight vehicles, as well as motorcycles which rely on the exchange of BSMs. The document covers vehicle classes not addressed in SAE J2945/1 and SAE J3161/1.

J2735SET_202309
This Abstract Syntax Notation (ASN.1) File is the precise source code used for SAE International Standard J2735. As part of an international treaty, all US ITS standards are expressed in "ASN.1 syntax". ASN.1 Syntax is used to define the messages or "ASN specifications". Using the ASN.1 specification, a compiler tool produces the ASN library which will then be used to produce encodings (The J2735 message set uses UPER encoding). The library is a set of many separate files that collectively implement the encoding and decoding of the standard. The library is then used by any application (along with the additional logic of that application) to manage the messages. The chosen ASN tool is used to produce a new copy of the library when changes are made, and it is then linked to the final application being developed. The ASN library manages many of the details associated with ASN syntax, allowing for subtle manipulation to make the best advantage of the encoding style.
