                     V2X Communication 
Technology
V2X communication technology will allow vehicles to communicate 
with one another, the traffic infrastructure and the cloud. This will 
enable access to critical safety features such as vehicle-to-vehicle 
(V2V) warnings of imminent collisions, traffic sign recognition 
technologies that leverage information from road side units to avoid 
hazards and real-time incident alerts to warn other drivers about 
collisions or obstacles in the roadway ahead.
V2X system dramatically improves 
safety and mobility. With an 
awareness of other vehicles on the 
road, the system alerts drivers to 
potential risks as they happen.
On-board sensors use GPS signals to 
determine a vehicle's location on the 
road and help predict potential 
hazards by "seeing around corners" 
or behind large vehicles.
The V2X Communication Technology also can use 
alternative transmitters such as cellular signals from 
nearby cell towers to broadcast traffic information 
from surrounding areas to the car. This helps drivers 
make more informed decisions about where they are 
going and allows them to plan a route.
By securely exchanging information such as speed, 
acceleration, position and direction of travel, road 
safety can be significantly improved. Drivers get 
alerts about dangers in their path. Collisions on our 
roads can be dramatically reduced; estimations show 
that approximately 80% of accidents will be avoided.
Improved mobility is also a direct result of this technology.  
Vehicles will be coordinating their maneuvers as they 
synchronize to avoid traffic jams or to drive through a 
green wave. V2X also provides real-time accurate data of 
vehicle status for accurate future movement prediction, 
and intention, such as turn lights.  This way traffic flows 
much better, resulting in less time in traffic for everyone.
In autonomous vehicles, V2X complements 
the information coming from other sensors, 
as it is the only available sensor in non-
line-of-sight scenarios and works in rough 
weather and poor lighting conditions.
V2X communication is heading to mass-
market adoption as the world’s largest 
OEMs announced intentions to equip their 
new car models with the technology. A few 
years down the road, we will not 
understand how we ever drove without it!
