DSRC COMMITTEE LOOKS AT
VULNERABLE ROAD USER
CRASHES
Vulnerable Road User crashes (VRU)
are an increasing proportion of US
and European road fatalities and
are the predominate road fatality
type in the world. The prevalence of
handheld devices carried by VRU and
the potential for data exchange or
messaging with vehicles prompts the
SAE DSRC Committee to consider
VRU standards that may leverage
off V2V and V2I data element and
performance levels.
SAE J2945/9, a work in progress
document titled "Performance
Requirements for Safety
Communications to Vulnerable Road
Users," seeks to
* determine Vulnerable Road User
(VRU) use cases enabled by
Cooperative ITS
* identity relevant SAE DSRC Technical
Committee standardization activities
and define output support VRU
applications
* make recommendations for
performance levels, links to existing
standards and as necessary, embark
on new standard development

NEW V2V COMMUNICATIONS STANDARDS WILL ENHANCE
VEHICLE SAFETY
Two important SAE technical standards standardize the data message
sets used in Vehicle-to-Vehicle (V2V) communications and establish the
parameters for a vehicle communication system to receive and transmit the
message sets.
A revised fifth edition of SAEJ2735™, "Dedicated Short Range Communications
(DSRC) Message Set Dictionary," was published in January. SAE J2945™/1,
"On-Board System Requirements for V2V Safety Communications" is expected
to be published soon. Both standards are developed by the DSRC (Dedicated
Short Range Communications) Committee.
These cross-cutting industry standards allow vehicle OEM's and other
developers to build interoperable V2V systems that will ensure that vehicles
from different manufacturers are able to successfully communicate with
each other.
"V2V technology is an important and growing safety technology for future
vehicles," Jack Pokrzywa, Director of Ground Vehicle Standards for SAE
International, said. "These new standards establish the parameters on how
vehicles communicate with each other, thereby improving their safety
effectiveness by designing interoperable systems."
J2735 specifies a message set, and its data frames and data elements
specifically for use by safety applications intended to utilize 5.9 GHz DSRC
for V2V communication systems. This standard also supports interoperability
among DSRC applications through the use of a standardized message set, and
its data frames and data elements. Common and interoperable message sets
are the cornerstone of V2V safety applications.
J2945/1 provides on-board system requirements for V2V safety
communications and specifies the parameters for a system to transmit and
receive the SAE J2735-defined safety messages over a Dedicated Short Range
Communications (DSRC) wireless communications link. It also ensures that
the exchange of safety messages in V2V safety communications provides the
desired interoperability and data integrity to support the performance of the
envisioned safety applications and provides the information necessary to build
interoperable systems that support select safety applications.
It is expected that both standards will be cited by the National Highway
Traffic Administration's (NHTSA) in its upcoming Federal Motor Vehicle Safety
Standard Number 150 (FMVSS 150) rulemaking which will require vehicle-tovehicle (V2V) communication capability for all light duty vehicles and create
minimum performance requirements for V2V devices and messages.

CONSENSUS BASED STANDARDS AND MORE FROM SAE INTERNATIONAL
While consensus-based standards are the cornerstone of the program responsible for developing more
vehicle technical standards than any other organization, SAE International also offers a full range of
development capabilities for global standardization including:
* Standards Consortium Administration
* Cooperative Research
* Database Creation and Management

2

* Accreditation and Certification
* Committee Management
