US DOT report - DSRC ready for deployment

10. February 2016

SAE reported:

The US Department of Transportation (USDOT) has released its report to the United States Congress assessing the status of dedicated short-range communications (DSRC) for connected vehicle technologies. The findings are that they are ready for deployment. The USDOT's report, The Status of the Dedicated Short-Range Communications Technology and Applications, also considered known gaps as well as potential issues with DSRC technology and some of its applications. The report describes a recommended implementation path using real-world traffic and roadway examples. This path begins with safety for crash avoidance alerts and warnings and moves through to fully automated driving technologies.

In this context, the term DSRC refers to the set of WAVE standards (IEEE 1609.x) that were revised during 2015. The formats of the WAVE messaging and the WAVE service advertisement message are harmonized with ISO. ISO specified this scaleable approach in ISO 16460. ISO 29281-1 (Fast Networking & Transport Protocol) and ISO 24102-5 (Fast Service Advertisement Protocol) currently are updated to support all features specified in ISO 16460.

An ITS station unit (ISO 21217:2014) compliant with the new editions of ISO 29281-1 and ISO 24102-5 is fully interoperable with IEEE WAVE devices used in USA with respect of the messaging protocol and the service advertisement protocol.

The ISO standards support more features than the WAVE standards, especially

Dr. Fischer from ESF GmbH was intensively involved in this harmonization work. He drafted the first harmonized version of IEEE 1609.3. He is editor of ISO 16460, ISO 29281-1, and ISO 24102-5.

This harmonized solution (ISO 29281-1, ISO 24102-5) will be part of the core technology for hybrid communications in ITS (C-ITS, Urban ITS, ...) standandardized by ISO.
