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.

This SAE Standard specifies a message set, and its data frames and data elements, for use by applications that use vehicle-to-everything (V2X) communications systems.

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 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.

This SAE Information Report identifies some enhancements that may be applied to V2X standards, addressing new use cases that require or benefit from high levels of position precision and integrity.

The report specifies a data set (DS) to be provided by connected signalized infrastructure (CSI) to connected vehicles (CVs) to support traffic signal related application information at locations other than typical intersections. Included are a concept of operations, requirements, design, and DS structure definitions developed using a detailed systems engineering process.

This document provides a mapping between provider service identifiers (PSIDs)—allocated to SAE by the appropriate registration authorities—and SAE technical specifications of applications identified by those PSIDs. It is intended that this document will be updated regularly, including information about the publication status of SAE technical reports.

This document defines an application interface that supports sharing of school bus status information such as student loading/unloading, students crossing, and other school-bus related actions. With the goal of increasing safety of students during this portion of their journey to/from school and school activities, this document provides support for corresponding V2X applications related to school bus safety, especially when slowing and stopping.

This document specifies a set of rules for the creation and management of the V2X ASN.1 Module Collection. These rules apply to the development of any message, data element, data frame, or any ASN.1 Entity that is part of the V2X ASN.1 Module Collection, regardless of the SAE technical report in which it appears. The intended audience for these rules includes every technical committee (TC) under the SAE V2X Communications Steering Committee.

This recommended practice will define a reference high-level architecture for precise positioning system of passenger vehicles for V2X applications, with the goal of delivering submeter positioning accuracy performance as much as possible. The architecture will comprise GNSS (aka GPS) and IMU (Inertial Measurement Unit) with the options for including other sensors, such as wheel encoders, camera, lidar, as well as maps. The positioning system is intended to estimate absolute position, course angle, and speed of the vehicle in a global coordinate system. This document will also offer implementation recommendations.

This recommended practice will specify the review, testing, and analysis steps for certifying the performance of precise positioning system of passenger vehicles. The goal of the certification is to validate that the positioning system delivers the level(s) of performance that it claims. The levels of performance may include position accuracy at different confidence levels and integrity metrics such as protection level, risk level, and alert limit.

This SAE Standard serves as the guidance document for the J2945/x family of standards as illustrated in Figure 7. It contains cross-cutting material which applies to the other J2945/x standards, including recommended practice for the use of Systems Engineering (SE) and generic DSRC interface requirements content. The scope for the DSRC system environment is to provide for the information exchange between a host vehicle and another DSRC enabled device, a device worn by or otherwise attached to a traveler, a roadside device, or a management center, to address safety, mobility, and environmental system needs. The audience for this document includes the technical teams of developers of the J2945/x documents and the implementers of the applications which are based on the J2945/x documents.
