• SAV testing experience in multiple

cities (Las Vegas, San Ramon)

• Need temporary signal controller

installation in parking lots in each

city

• Expensive, time consuming,

unnecessary

Pain Points

• Confusing and competing sales

pitches

• Expensive and time consuming test

setup & disassemble

• Lack of access to SAV for testing

needs

• Resource drain to align all

stakeholders

10

• State-of-the-art lab to test V2I and

V2V technologies to enhance

safety and reduce congestion

• Equipped with advanced traffic

signal controllers, video detection,

Dedicated Short Range

Communication (DSRC)/5G

communication etc.

• Open to OEMs, Transit Agencies,

Cities & Counties, DOTs,

Universities, Vendors

CAV Signal Lab

Introduce the AAA V2I Lab

DSRC On Board Unit (OBU):

Receives traffic data from and

sends car data to RSU

Communication: 5.9 GHz / 5G

DSRC Roadside Unit (RSU):

Provides traffic data to and receives

vehicle data from OBU

Communication: 5.9 GHz / 5G

Connected Autonomous

Vehicle (CAV):

Navigates intersection based on traffic

data feeds from RSU and OBU

Communication: 5.9 GHz / 5G

Roadside Information Hub:

Collects traffic data and uploads to cloud;

Provides edge data processing capabilities

Communication: Cellular, DSRC, 5G, Fiber

Testing Facility

“V” Model of Development

14

• 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

V2I Applications

• Red-light violation warning (RLVW)

• Curve speed warning (CSW)

• Signalized left turn assist (SLTA)

• Spot weather information warning—reduced speed (SWIW-RS)

• Vulnerable Road User Protection (Warning from Bikes and Peds)

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

Enhance community well-being

ability to allow priority passage of public

transit buses and emergency vehicles

V2X Technology Benefits

Reduce citizen complaints

improve efficiency on the road

and reduce congestion

Increase safety

ability to detect invisible obstacles to line-

of-sight only vehicle sensors
