5	Communications System for Security Four scenarios: Mostly cellular system Mostly cellular with some installation of DSRC RSE “All DSRC” CAMP Phased Deployment Scenarios Three principal cost drivers: On-Board Equipment (OBE) is a significant in-vehicle cost in all scenarios Road-Side Equipment (RSE) is a significant infrastructure cost in an “All DSRC” scenario Cellular may be a significant cost in those scenarios that rely on it for certificate delivery
6	Communications System for Security Delivery of the Certificate Revocation List (CRL) is expensive and technically demanding With incremental or no CRL delivery: Certificate Authority maintains CRL, but does not distribute. Instead, certificates are withheld from misbehaving vehicles. Cellular data costs drop substantially. With no CRL distribution, OBE costs are the most expensive part of the system: OBE costs vary slightly for each scenario due to cost and power consumption of subcomponents OBEs are necessary for safety, so the incremental costs to serve the function of communicating to the SCMS are relatively small Results are very sensitive to inputs; uncertainty in conclusions is high
7	Communications System for Security For an “All DSRC” scenario, the number of RSEs nationwide depends on risk tolerance and coverage requirements: Estimates vary from 1300 RSEs to150,000 RSEs Unanswered Questions: What level of coverage is acceptable? How frequently must a vehicle interact with the system? Lowest cost scenario hinges on number of RSEs required Cellular scenarios are lowest cost if “All DSRC” requires many RSE OBE costs become most important if “All DSRC” requires fewer RSE
8	Communications System for Security Operational issues and unknown variables dramatically impact costs of cellular options Cellular scenario highly sensitive to changes in the misbehavior rate, CRL variable data size, and peak prices Installation, operation and maintenance of RSE’s pose significant challenges for DRSC options Placement of RSE’s in state or locally owned equipment cabinets and rights-of-way would require a significant implementation permitting, coordination and system integration effort Placement of RSE on private property may be an alternative but would also require a strategy for implementation

10	Legal Policy - Scope of Authority NHTSA has authority to support: Key aspects of V2V communications Regulation of critical equipment, messages and applications if related to safety Provision of the security required to support a V2V rule by a non-Federal entity, as through a procurement or other form of agreement or indirectly via a V2V regulation FHWA does not have authority to require installation of roadside infrastructure
11	Other Legal Policy Issues Intellectual Property Privacy Need to distinguish between trip-trackability and ability to identify bad actors on the system DOT will do comprehensive review of any final system and involve appropriate privacy community
