MANAGED FREEWAYS
A Holistic Approach for
Fully Controlling Freeway Operations
Managed Freeways provides a comprehensive approach to fully
control freeway operations

Managed Freeways rethinks the
way we manage freeways

Builds upon ITS, ATM, ICM and
dynamic demand management
tools of managed lanes.

Provides a comprehensive
package of strategies to fully
control freeway access to
manage demand and optimize
traffic flows.

Integrated Corridor Management shares some common
elements with Managed Freeways

ICM provides a framework
for coordinating various ITS
elements

Incident management,
adaptive ramp metering,
arterial system integration
and traveler information are
integral elements of ICM
Source: Alameda County Transportation Commission
Integrated Corridor Management provides coordinated corridor
management

ICM can provide enhanced
traveler information and
facilitates coordinated
response to congestion and
incidents

ICM does not typically
synchronize freeway traffic
flows to accomplish full
control of corridor traffic
operations

Highly precise data and advanced system management tools
are key to Managed Freeways


Managed freeways
synchronizes the flow of
vehicles entering and exiting
the freeway to those already
on the freeway.
Provides real time demand
management to control traffic
and optimize overall freeway
efficiency

VicRoads Managed Motorways is the only proven strategy to
reliably control freeway operations
 Managed freeways have minimized instability in traffic flows on M1:
 Integrated system ensures components work together to
sustain traffic flows.
 Bottlenecks have been substantially eliminated.

Managed Freeways is getting growing interest
in the United States

Colorado and Utah DOT’s have
undertaken initial feasibility
assessments


Managed freeways has been
identified as a viable strategy
for both candidate corridors
I-25,
Denver, CO
Both agencies are seeking
funding for initial deployments
I-15,
Salt Lake City, UT
Initial evaluation shows great potential for Managed Freeways
in the United States

Preliminary results show
the potential for managed
freeways to effectively
eliminate recurring
congestion on I-15

Total trip times estimated
to improve 11%

Total delay estimated to
be reduced 37%

Managed Freeways requires a paradigm shift in
how we plan and manage freeways

Freeway planning has
typically been based on
hourly corridor volumes
Traffic flows are very volatile
and can fluctuate greatly in
very short periods of time

Managed freeways optimizes
traffic flows to match these
fluctuations and avoid traffic
flow breakdown

“Managed Motorways is not a trivial matter”
Markos Papageorgiou 2007
•
Managed freeways is not a small stepwise change to existing ramp
metering systems
• It will require a commitment to a new paradigm
•
Managed freeways is a multi-faceted solution that involves new skill sets,
communication systems, control systems, control engineering &
optimization
• These skills are not typically associated with DOT’s traditional functions
•
Unless you commit to all the critical elements of managed freeways you
cannot achieve the full benefits
