C-V2X drives
intelligent
transportation
Designed specifically for transportation,
cellular-vehicle-to-everything (C-V2X)
technology supports direct, low-latency
communication between vehicles
(V2V), roadside infrastructure (V2I),
and vulnerable road users (VRUs) such as
pedestrians (V2P) to inform safety-critical and
mobility-enhancing applications. When
complemented by cellular networks (V2N), C-
V2X makes transportation systems and the
entire ecosystem more efficient.
When vehicles are connected to everything
around them, road users and infrastructure
can coordinate their actions to make travel
safer — reducing crashes, injuries, and
fatalities on roadways. Because crashes and
other non-recurring incidents account for
approximately half of traffic congestion in
many parts of the world, enhancing safety
also helps to improve mobility which directly
correlates to sustainability.(i)
Wireless technologies are poised to
transform how transportation is delivered,
bringing tremendous opportunities to
improve efficiency and achieve tangible
sustainability benefits.
Connected transportation systems are
designed to support new roadside and driver
services that mitigate roadway incidents and
improve trip planning, transportation mode
choice, and traffic efficiency — enhancements
that also lower emissions and reduce fuel
consumption. Examples include real-time
route guidance to bypass congestion,
adjusting vehicle dynamics for optimal speed
with less braking and idling for lower
emissions and fuel use, and personal mobility
services for additional travel options.
Vehicle-to-Vehicle
e.g., collision avoidance safety systems
Vehicle-to-Infrastructure
e.g., roadside traffic signal timing/ priority
Vehicle-to-Network
e.g., real-time traffic/ routing, cloud services
Vehicle-to-Vehicle
e.g., collision avoidance safety systems
Vehicle-to-Pedestrian
e.g., safety alerts to pedestrians, bicyclists
