5.9 GHz DSRC
Advantages
Meets the requirements for privacy and
“anonymity by design”
Spectrum allocation gives
greater control over access/rules of use
Full integration for V2V and V2I
DSRC network can be nationally
scaled, works w/ high vehicle density
Limitations and Questions
No existing nationwide network―How much infrastructure is needed? Who owns, operates, and maintains?
High investment ― How to fund implementation,
operations, and
maintenance? Private sector business models that support safety needs? How to enable consistent national approach
if done privately
or by jurisdiction?
Will need to have some sort of
revenue stream or payment mechanism to support ongoing operations and maintenance.
Review of Options and Analysis to Date
Analysis to Date:
•Methodologies to
estimate amount of
infrastructure needed in support of V2V security result in an estimate of approximate 40,000 RSEs to cover metropolitan areas (possibly nationwide footprint –further analysis is being pursued). May be able to leverage security infrastructure to support V2I applications, but will this be enough to provide V2I coverage and create benefits?
•This amount would
support ability for
near 100% of vehicles to receive certificates and revocation lists daily, thus minimizing security and safety risks.
