Dedicated Short Range Communications (DSRC) Performance Requirements for V2V Safety Awareness

DSRC (Dedicated Short Range Communication) Tech Cmte
  • Ground Vehicle Standard
  • J2945/2_201810
  • Current
Published 2018-10-30 by SAE International in United States
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.

Dedicated Short Range Communication (DSRC) Systems Engineering Process Guidance for SAE J2945/X Documents and Common Design Concepts™

DSRC (Dedicated Short Range Communication) Tech Cmte
  • Ground Vehicle Standard
  • J2945_201712
  • Current
Published 2017-12-07 by SAE International in United States
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.

Vulnerable Road User Safety Message Minimum Performance Requirements

DSRC (Dedicated Short Range Communication) Tech Cmte
  • Ground Vehicle Standard
  • J2945/9_201703
  • Current
Published 2017-03-21 by SAE International in United States
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]]. While other wireless media may be used to deliver the PSM, DSRC is explicitly assumed in this document, because of anticipated regulatory ruling in the United States and other countries requiring vehicles to be equipped with a DSRC-based safety system using V2V communication. This recommended practice is limited at this time to communications between the VRU device carried by walking pedestrians and DSRC equipped vehicles. Later versions may incorporate improvements based…

Dedicated Short Range Communications (DSRC) Message Set Dictionary

DSRC (Dedicated Short Range Communication) Tech Cmte
  • Ground Vehicle Standard
  • J2735_201603
  • Current
Published 2016-03-30 by SAE International in United States
This SAE Standard specifies a message set, and its data frames and data elements, specifically for use by applications intended to utilize the 5.9 GHz Dedicated Short Range Communications for Wireless Access in Vehicular Environments (DSRC/WAVE, referenced in this document simply as “DSRC”) communications systems. Although the scope of this Standard is focused on DSRC, this message set, and its data frames and data elements, have been designed, to the extent possible, to be of potential use for applications that may be deployed in conjunction with other wireless communications technologies as well. This Standard therefore specifies the definitive message structure and provides sufficient background information to allow readers to properly interpret the message definitions from the point of view of an application developer implementing the messages according to the DSRC Standards.

Dedicated Short Range Communications (DSRC) Message Set Dictionary™ ASN file

DSRC (Dedicated Short Range Communication) Tech Cmte
  • Ground Vehicle Standard
  • J2735ASN_201603
  • Current
Published 2016-03-30 by SAE International in United States

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.

Published 2016-03-30 by SAE International in United States
This standard specifies the system requirements for an on-board vehicle-to-vehicle (V2V) safety communications system for light vehicles1, including standards profiles, functional requirements, and performance requirements. The system is capable of transmitting and receiving the Society of Automotive Engineers (SAE) J2735-defined Basic Safety Message (BSM) [1] over a Dedicated Short Range Communications (DSRC) wireless communications link as defined in the Institute of Electrical and Electronics Engineers (IEEE) 1609 suite and IEEE 802.11 standards [2] – [6].
