SAE International Launches Two New Technical Standards that Will Play a Key Role in NHTSA’s Vehicle-to-Vehicle (V2V) Rulemaking

Dateline: March 31st 2016
SAE International has published two important new technical standards that 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

DSRC is a vehicle to vehicle (V2V) and vehicle to roadside infrastructure (V2I) message set and methodology for radio communications which is based on 5.8~9GHz radio links. The most common message is the “Basic Safety Message” (BSM) whereby vehicles exchange their estimated position, velocity, and acceleration vectors ten time per second.

We congratulate the SAE Dedicated Short Range Communications (DSRC) committee members on this milestone.   A staff member of SCSC (Mr. DC Kelley) has been the primary editor of the SAE J2735™ Message Set effort since its inception, working hand in hand with other developers in the US and around the world to reach a consensus point where US and international deployment is now taking place after a prior decade of field testing.  This is but one over four dozen standards that SCSC has developed for the ITS and telematics industry.  DSRC technology is one of the next evolutionary steps in vehicle to vehicle safety as well as vehicle to vulnerable road user safety (read: you when you are a pedestrian).

At SCSC, this is what we do when we are not doing vehicle RTK and simple NTRIP technology like SNIP.  The firm’s entire existence, formed nearly 20 years ago to develop and and provided testing services for sending DGPS over FM radio stations sub carriers (yet another standard which we authored) has been pursuing the goal that everybody, everywhere needs access to local corrections to make RTK solutions inexpensive for the masses.  This publication is a important milestone that is ready for world-wide deployment.  Combined with SNIP that today implements the technology for sending these messages into vehicles, correction coverage can easily be added in any geographical region.

A note to other DSRC practitioners: If you are working on one the US pilot test sites or another regional deployment, we can provide suitable SAE formatted DSRC corrections to you from our existing caster network, or provide you an enterprise SNIP node for your own use.  Of course we suggest you use snip, please contact us with your needs.  Our tool sets for ASN message development support as well as MAP/SPAT development are not handled on this, the SNIP support website.  The SAE standards and the J2735 ASN specification can be obtained from SAE here and here.
