Connected vehicles auto saftey FAQs
How can V2X technologies further enhance the safety benefits of automated vehicles (AVs)?
V2X technologies can supplement the information that comes from on-board sensors, cameras, and GPS technologies to provide even greater situational awareness. That can further improve automated vehicle decisions in safety-critical situations.
What kind of messages are transmitted using V2X communications?
Safety-critical information including speed, direction, brake status, and other information is exchanged. Often with range and detection capabilities that exceed the capabilities of sensor/camera/radar-based systems. These expanded capabilities can allow vehicles to “see” around corners or “through” buildings or other vehicles. That means V2X-equipped vehicles may perceive some threats sooner and could provide warnings earlier.
Why is the public even safer when the auto industry has all 75 MHz of spectrum?
Sufficient spectrum is necessary to facilitate the development and growth of V2X applications. Without all 75 MHz of spectrum, these applications could be significantly hindered. The full 5.9 GHz band is needed to improve safety, mobility and sustainability.
This includes:
- Low-latency V2V applications to support automated vehicles
- Public safety applications for ambulances and other emergency responders
- V2I applications to decrease traffic congestion
- Vehicle to pedestrian applications to improve urban movement and safety.
What will happen if the 5.9 GHz is re-channeled?
Re-channelization would result in critical V2X safety messages being moved to the 5.9 GHz band’s upper portion, where there could be new sources of potential interference from high-power public safety communications.
Further, rechannelization could cause critical safety communications in the lower band to be subject to in-band interference from unlicensed transmissions aggressively using the band at the same time and place as V2X technologies.
