Connected Vehicle

We want stationary objects and moving objects to communicate.
with Argo test vehicles at a particularly complex intersection.
The intersection at Lincoln Road and Lenox
Avenue in Miami's South Beach consists of narrow
two-way streets with buildings and palm trees close to
crosswalks. It's adjacent to a popular outdoor mall with
a constant stream of cars, pedestrians and bicycles.
The intersection is difficult enough for human
drivers to navigate and could create blind spots for
the sensors on an AV. If an AV sensor's line of sight is
obstructed because of a building, tree or large truck, the
smart node can provide information on what's blocked
from the AV's view, helping it to react accordingly. The
smart node also can provide a comprehensive view of
the intersection before an AV even arrives, so that it can
process the information and prepare for driving through.
Before Motional launched a public AV pilot with
Lyft in Las Vegas in 2018, the company worked closely
with Las Vegas-area transportation agencies to install
DSRC units to allow Motional vehicles to " talk " to
traffic lights and other roadway infrastructure. To date,
Motional has equipped more than 120 intersections
with DSRC technology that can be used by not just
by Motional AVs, but any smart, connected vehicle.
Map and infrastructure updates
One vexing problem for AVs is temporary road
construction and sudden changes to infrastructure.
Argo AI works with the eight cities in which it operates,
including Munich and Hamburg, to get updates on
construction info. " We work with Miami to update us
on road construction and build it into our 3D maps, "
said Alan Hall, director of communications at Argo.
Argo's maps also are updated when the company's
vehicles come across changes in roadway infrastructure.
For instance, if an Argo vehicle's sensors detect a
new stop sign, it archives this information and shares
