Summary Information
This research evaluated the potential benefits and costs of vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technologies developed for the SAFESPOT program in Europe (EU-25). The primary goal was to establish benefit-to-cost ratios for bundled applications and account for varied levels of market penetration.
V2V Technology Bundle
System costs included costs for in-vehicle components, support infrastructure, and operations and maintenance costs over the lifetime of the system (roughly 12 years) using a discount rate of three percent. Implementation costs included a five percent mark-up based on the sum of component costs. A digression rate of 16 percent was used to account for economies of scale and reduced production costs when market penetration rates double. Subject matter experts were surveyed to estimate market penetration rates of these technologies in new vehicles.
Benefit-to-cost ratios were calculated from the estimated safety impacts, accident trend data, cost estimates, and forecasted market penetration rates for the SAFESPOT systems.
FINDINGS
Benefit-to-cost ratios for V2V ranged from 1.0:1 to 1.1:1 with fleet penetration rates of 6.1 to 8.7 percent by 2020. These findings were in consistent with previous studies that indicated V2V systems require market penetration rates above five percent.
Benefit-to-cost ratios for V2I, however, were clearly below 1, ranging from approximately 0.2:1 to 0.1:1 with fleet penetration rates of 5.4 to 9.5. The calculation was based on an infrastructure equipment rate of 50 percent and the low rate was primarily due to the high cost of equipment for large-scale infrastructure projects.
Additional analysis of 100 percent market penetration showed significant safety impacts with 7.1 percent fewer fatalities in the V2V case, and 8.9 percent fewer fatalities in the V2I case.
V2V Technology Bundle
- Lateral Collision Warning: Road intersection safety
- Road Departure Warning: Road condition status - slippery road
- Longitudinal Collision Warning: Speed limitation and safe distance
- Cooperative Intersection Collision Prevention: Basic application
- Hazard and Incident Warning: Reduced friction or visibility
