U.S. Department of Transportation Seeks Public Comments on Technologies Beyond Dedicated Short-Range Communications

By SEMA Washington, D.C., Staff

The U.S. Department of Transportation (DOT) has requested public comments on technologies available to assist in connecting vehicles to other vehicles (V2V), infrastructure (V2I) and pedestrians (V2P). These communications are collectively known as V2X.

In recent years, the DOT has focused on Dedicated Short-Range Communications (DSRC) technology as it establishes standardized performance requirements for V2V messages operating in the 5.9GHz band. In an effort to remain technology neutral, however, the DOT is seeking public comments on Cellular-V2X, 5G New Radio and any other technologies that are being developed for the same purpose.

The DOT has posed a number of questions such as: What are the advantages and disadvantages of each technology? What is the timeframe for deployment of technologies not yet in production? Can all of the technologies operate in the same spectrum without interference? Will it be possible for the technologies to be interoperable (ex: DSRC vehicles speaking with C-V2X vehicles)?  What are the cybersecurity concerns for each technology, especially if they are interoperable? Comments are due January 25, 2019.
