This Abstract Syntax Notation (ASN.1) file precisely specifies the structure of the data used to support the implementation of SAE International Standard 2945/6. Using the ASN.1 specification, a compiler tool can be used to produce encodings as required by the encoding rules identified in the standard. Both this file and the SAE J2735 ASN.1 files are necessary to collectively implement the data exchange described in the J2945/6. The combined library can be used by any application (along with the additional logic of the application) to exchange the data over an interface conformant to J2945/6. SAE J2945/6 specifies the interface and requirements for Cooperative Adaptive Cruise Control (CACC) and Platooning. It provides the information necessary to build interoperable systems that support CACC, which rely on the exchange of Cooperative Control Messages.

This standard provides the guideline for enhancements to adaptive cruise control (ACC) by the addition of wireless communication from relevant vehicles (V2V) and/or the infrastructure (I2V) to augment the ACC active sensing capability. The CACC system operates under driver responsibility and supervision and is limited to the following: Does only longitudinal control of the vehicle. Uses time gap control strategy similar to ACC. Motor vehicles covered in the scope of this document include light and heavy vehicles. The message elements to realize CACC and platooning are part of the scope. The initial release covers definitions for CACC and platooning and requirements for CACC, while a subsequent release will cover the platooning requirements.

This WI is proposed to provide an Information Report about: - To research and review various projects and works for V2X applications using the Uu interface what’s been done before (Smart ITS 2.0 project in Seoul city ) - To identify the usefulness of Uu interface for the V2X services - To list concerns of using the Uu interface for the V2X services and to find ways to address those concerns - To find use cases and scenarios which can be appropriate to use the Uu interface as the V2X access technology - To find use cases and scenarios which can provide more enhanced V2X applications to many road users if using the Uu interface combined with the short-range communication - To analyze which part needs to be standardized in the ITS architecture based on the USDOT reference model, when it is including the Uu interface - To investigate whether the standards developed with the assumption of short-range communication can be reused for the Uu-based operations as they are, analyze what changes are necessary to facilitate the use of Uu interface (e.g., the amount of data traffic, triggering conditions), and identify areas for potential future standardizations

This SAE Standard provides requirements to support applications for the maneuver sharing and coordinating service (MSCS) beyond broadcast of basic safety messages (BSMs). This is to improve road safety and traffic efficiency by sharing and coordinating vehicle maneuvers via vehicle-to-everything (V2X) communications. This document lays out use case scenarios and defines vehicle-to-vehicle (V2V) application protocols, system requirements and message sets for MSCS. The defined message sets for MSCS will result in identifying new message types, data frames, and data elements for SAE J2735.

This project would provide use-case concepts, system requirements, architecture, wireless communication protocol and any associate messages to support automated marshalling (remote control) of vehicles in manufacturing plants, depots, parking lots and garages utilizing infrastructure. The infrastructure can detect objects and obstructions to help guide automated vehicles starting from vehicle onboarding, maneuver completion and off-boarding. Using wireless communication, the application protocol allows infrastructure to guide and coordinate the vehicles to follow and maneuver along paths defined by the infrastructure in controlled environments. 

This standard describes the message content and the requirements for VRU safety applications. The document is based on the previously published version with more use cases and data contents to accommodate more VRU types and safety needs.

This recommended practice will provide guidance on the requirements of a V2X application to enable drivers (human or machine) to exchange courteous messages to resolve traffic related misunderstandings, conflicts and to minimize anxieties. Such system can lead to improving traffic safety. The related initial work in the field of driver-to-driver communication have been conducted and the research result have been published. The focus of this recommended practice is on use case definitions, information exchanges among the road users such as among multiple vehicles, or between a vehicle and a pedestrian. This effort may result in identifying new messages, data frames and data elements in SAE J2735

This Abstract Syntax Notation (ASN.1) File is the precise source code used for SAE International Standard J2945/2. 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 J2945/2 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 Document specifies DSRC interface requirements for V2V Safety Awareness applications, including detailed Systems Engineering documentation (needs and requirements mapped to appropriate message exchanges). These applications include: Emergency Vehicle Alert, Roadside Alert, and Safety Awareness Alerts for Objects and Adverse Road Conditions. This document extends the V2V Communications capabilities defined in J2945/1 to support these applications, and the National ITS Architecture. The purpose of this SAE Document is to enable interoperability for V2V Safety Awareness communications.

This document provides a description for a V2X-capable device such as a vehicle, an infrastructure or a portable device to broadcast its perception information of other road users/objects nearby, to realize cooperative perception sharing, and to improve the perception performance of other V2X-capable devices/systems. #11;The concept of such perception sharing system can be: The host system is capable of transmitting and receiving V2X messages such as BSM and PSM messages. In the meanwhile the host system is capable of detecting nearby road users/objects such as foreign objects, vehicles and pedestrians. The host system can determine whether the detected objects are V2X enabled or not, and translate the detected objects to messages such as a new cooperative perception message, and/or an extension of messages such as BSMs/PSMs, and broadcast these messages.

This document provides recommendations of safety message minimum performance requirements between a Vulnerable Road User (VRU) and a vehicle. It addresses the transmission of Personal Safety Messages (PSM) from road user devices carried by pedestrians, bicycle riders and public safety personnel, to provide driver and vehicle system awareness and potentially offer safety alerts to VRUs. This document includes the recommendation of standards profiles, function descriptions and minimum performance requirements for transmitting the SAE J2735-defined PSM [1] over a Dedicated Short Range Communications (DSRC) Wireless communication link as defined in the Institute of Electrical and Electronics Engineers (IEEE) 1609 and the IEEE 802.11 Standards [[1]]-[5]].
