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…”

Step 1: equipped vehicle hears RSU (DGPS), and corrects absolute positionStep 2: detailed intersection map broadcast message receivedStep 3: vehicle calculates position on map and distance to stop using DGPSStep 4: vehicle receives signal phase and timing advisoryStep 5: if signal timing indicates probable violation, warning is provided.Step 6: driver brakes to avoid entering collision zone during red light interval.

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
