Dedicated Short Range Communication (DSRC)
Bi-directional wireless communications permitting secure and fast messaging needed for safety applications.
These communications occur in a 75 MHz band of the 5.9 GHz spectrum
Vehicles communicate with each other by passing and interpreting messages
Vehicles disseminate Basic Safety Messages (BSM) 10x a second based on the SAE J2735 Standard
A vehicle that receives the message processes the data and assesses collision threat that in turn and triggers either an automatic response or driver warning

Cellular V2X (C-V2X)
C-V2X communications is an emerging technology that works off of LTE (Long-Term Evolution) features and cellular networks to provide V2X capabilitiesSupports Direct Communications (V2I/V2V/V2P)– independent of cellular networks based on PC5 interface using 5.9 GHzAlso supports Vehicle to Network (V2N) applications for longer-range interactions

Comparison
DSRCAdvantages
Established technology, Low Latency
Capable of functioning at high speeds and adverse weather conditions
Global harmonization of standards
DisadvantagesRange Limited to 1000 m
Requires OBU and RSU to be deployed
No evolution path
C-V2XAdvantages
Envisioned to support IoT and Smart Cities
More reliable at high speeds and long ranges
Does not require separate OBU
DisadvantagesEvolutionary, not expected until 2020
Questions about connectivity / lack of coverage in rural/sparse areas
Privacy concerns as data is passed through cloud

Legal Battle over V2X
FCC ET Docket No. 13-49 (reconcile use of 5.9GHz between DSRC & Wi-Fi)“Detect and Vacate” - DSRC and Wi-Fi would share the spectrum, unlicensed devices would detect DSRC operations and vacate the spectrum (Proposed by CISCO, Supported by the ITS and Auto industry)
“Rechannelization” – Split the DSRC into 2 contiguous blocks (Proposed by Qualcomm, Supported by other blocs)
NHTSA NPRM: 49 CFR Part 571 / Docket No. NHTSA-2016-0126Mandate DSRC vehicle-to-vehicle (V2V) communications for new light vehicles and to standardize the message and format of V2V transmissions

Conclusions
Embrace and support V2X – it is here, think less about the technology and more about how it will change mobility and safety
Integrate and process Big Data generated by V2X
Adapt traffic management as traditional roadside devices and 511 systems become obsolete
Promote Connected Mobility and Holistic Traffic Management
