• OEMs and Cities do not have to
build their own lab for V2X testing
• Equipment evaluation from multiple
vendors before deployment
• Feature and interoperability testing
before deployment
• Demonstration to key stakeholders
(Council members, Maintenance
crews, etc.) for buy-in

DSRC vs C-V2X
DSRC:
• Point-to-point
• Since 2004
• Sizeable deployments
• Uses 5.9GHz spectrum
• Toyota, Europe
Cellular V2X (C-V2X):
• Point-to-point
• Since 2016
• Deployments in 2022
• Uses 5.9GHz spectrum
• Ford, China
AAA will support both technologies

Sensors and V2X are Complementary
Vehicular Sensors:
• Point-to-point
• Imprecise communication
• Communicate with nearest neighbors
• Line-of-sight
• Short distance
• Independent of sensors on other cars
V2X:
• Point-to-point
• Precise communication
• Communicate with non-nearest neighbors
• Non-line-of-sight
• Longer distance (100s of meters)
• Dependent on interoperable V2X devices in other cars
