then fewer people will drive cars and
everybody wins.” Speaker alerts will
prevent drivers running red lights or
holding up traffic at green lights due
to smartphone distraction. Mulligan
also envisages giving freight vehicles
intersection priority at off-peak times
to incentivise their avoidance of busy
roads in rush hour.
With comparatively few CVs on
the road, non-connected vehicles
and vulnerable road users can
participate in North Fulton’s digital
safety environment by downloading
AII’s free TravelSafely smartphone
app, which provides warnings about
road conditions and signal phase and
timing (SPaT) information. Camera
or radar trajectory detectors will
capture the position and velocity of all
non-connected vehicles, which could
receive TravelSafely messages via
dash-mounted phones. 5GAA is now
holding its July 2020 North American
Meeting in Atlanta, which will allow
automotive, telecom and silicon
industry members to experience
North Fulton’s connectivity revolution
at first hand.

Improvement District (NFCID)
has approved installation of
cellular vehicle-to-everything (C-V2X)
across 44 intersections in Atlanta’s
Fulton County, making it Georgia’s
first region to adopt the technology.
Applied Information Inc. (AII) will
provide its Glance three-way roadside
units, which encompass three forms
of connected vehicle (CV)
communications: C-V2X, DSRC and
4G LTE wireless broadband. These will
initially be used to prioritize emergency
and transit vehicles at intersections
and alert CV drivers to red and green
lights via in-car speakers.
“Turning traffic lights green
for emergency responders getting
to citizens in need is a day-one
application,” says AII president Bryan
Mulligan. “But now their fire truck
can also talk to the cars around them.
Instead of wondering where the siren
is coming from, your speakers will
say, ‘Emergency vehicle approaching
from the right!’ We will also give
priority to transit vehicles, which
are the big hope for Atlanta’s traffic.

Improving safety
USDOT research suggests
widespread C-V2X deployment could
prevent 80% of unimpaired multivehicle
crashes. “A lot of fatalities are
caused by conflicts like left turns that
don’t go well or running each other
off the road,” says Armstrong. “This
technology can solve those conflicts,
creating a layer of protection around
every single car and becoming a
digital seat belt for our generation.”
C-V2X may also enable AVs to
resolve congestion problems in
future, rather than merely adding to
them. “AVs have a broad suite of
