What Can Connected Vehicle Technology Do?
Supported Safety Applications
This is great ! …but the overall effectiveness of these networked V2V systems depends on the number of installednodes…
“We are extremely encouraged by the research…[that] point[s] to Connected Vehicle Technology
as the next major safety breakthrough. In fact, vehicle-to-vehicle safety applications
could potentially address up to 80 percent of vehicle crash scenarios involving
non-impaired drivers…”

Summary and Conclusions
• V2V shows promise for crash avoidance applications
• To achieve maximum value, accelerate deployment with
aftermarket retrofit device installations
• V2X including traffic signals can also have safety and mobility
benefits without requiring large penetration %’s
• V2X integrated with other safety sensors is also a possible
stop gap measure
