Active Traffic Management Fact Sheet

Active Traffic Management Fact Sheet
 ATM
What is an Active Traffic
Management (ATM) system?
An ATM system provides the ability
to dynamically manage congestion
based on prevailing and predicted
traffic conditions.
What will it look like?
The Project Neon ATM system will
feature full-color, high-resolution
dynamic message signs over the
freeways that will provide real-time
information to motorists about
alternate routes, incidents, and
traffic restrictions.
How will it help drivers?
The message signs will be far more
sophisticated than the existing
dynamic signage, and can be
programmed to inform motorists of
specific lane closures and blockages
that occur with traffic accidents or
construction. Signs will show the
status of every lane as motorists
approach the |-15/U.S. 95 “Spaghetti
Bowl” Interchange that sees 300,000
vehicles daily and 25,000 lane
changes per hour.

= HOW IT WORKS:
The ATM system will provide
advanced warning and clear
direction that optimizes driver
expectations through a
well-defined notification system
before, during, and after
construction. Seamless display
signs will span all lanes and
provide lane-specific variable
speed limits, lane control, and
other messages.
= THE BENEFITS:
Improved trip reliability
Increased traffic movement
Reduced incidents
Reduced travel time, more
consistent travel time through the
corridor, increased safety
Improved traveler information,
increased detail and accuracy of
posted travel times
Consistent, reliable information
Potential to reduce the number
and severity of crashes
Increased support of work zone
management via advance
messages that allow for improved
traffic movement and reduced
crash rates in work zones

WHAT DRIVERS CAN EXPECT:
As a part of Project Neon, 12 Early
Construction ATM signs will be
installed and operational before
there are any construction-related
traffic impacts to the freeway, which
will provide a valuable traffic
management tool during
construction. Full-color dynamic
message signs will seamlessly span
all lanes and be located for optimal
sight distance at approximately
half-mile spacing. Strategic
placement of ATM signs will
disseminate lane-specific and
traveler information as vehicles
travel the highway.

WHAT IT DOES...
COLLECTS DATA: ATM detectors
throughout the corridor will
collect average speeds for each
lane of travel, allowing the ATM
system to accurately pinpoint
incidents and congestion and
actively manage traffic around
any incidents and work to reduce
the severity and duration of the
congestion. From this data, the
signs provide driver information
on speed, lane status, and road
status including traffic flow.
WATCHES TRAFFIC: CCTV
Camera coverage will allow ATM
operators to identify and confirm
incidents and congestion.
PROVIDES WARNINGS: The ATM
system will warn motorists of
problems ahead and direct traffic
to alternate lanes where
available.
IMPROVES YOUR COMMUTE:
The system will work to see
which lanes are less congested,
help reduce motorist speed
when appropriate and reduce
the chance of incidents due to
differences in traffic speed.
Hotline: 702.293.NEON
warn those on the highway of
problems ahead and will direct them
to alternate lanes where available.
When incidents occur and traffic
ahead is slowing down, the ATM
system will let drivers know in
advance of the incident so they can
reduce speed to avoid secondary
crashes.
TRAFFIC LANE MANAGEMENT
* The Project Neon ATM system will use
variable traffic signs and lane use
control to direct traffic to specific
lanes based on varying traffic demand.
e The system is focused on reducing
issues from merges at major
interchange ramps.
By effectively utilizing available
roadway capacity and managing traffic
flows, the ATM system reduces
congestion and crashes.
DYNAMIC RAMP METERING
Ramp meters will turn on during
congestion or turn off in times of no
congestion.
e Meters will improve traffic flow by
only utilizing ramp meters in real-time
during congestion periods.

VARIABLE SPEED LIMIT SIGNS
* Variable speed limit notices will be
provided on displays for each
entrance ramp.
* The system will dynamically and
automatically reduce posted speed
limits approaching areas of
congestion, incidents, or special
events.
Variable speed limits can reduce
the onset of highway congestion.
* The ATM system aims to maintain
flow, provide advanced warning to
travelers of congestion ahead, and
reduce risk of crashes.
