I-90 Rebuilding and Widening Project Goals Improve mobility and reduce congestion
Deliver a 21st century, state-of-the-art corridor linking Rockford to O'Hare
Accommodate transit options for the first time in the agency's history
Feature flexible infrastructure to add new "smart" features as needed
Incorporate the latest technologies available to enhance roadway safety

What is Active Traffic Management (ATM)?
7
High-tech gantries placed every half mile that provide real-time information to alert drivers to: • Nature and status of traffic incidents
ahead • Ability to drive in the shoulder lanes • Advisory speeds • Proposed alternate routes • Real-time lane closures and traffic
pattern changes
Helps facilitate the flow of cars to allow emergency vehicles to safely navigate the roadways and reach the incident scene more quickly
Stall ahead. Merge left and slow down
Who else is using ATM?
8
Netherlands Germany
Europe: multiple locations since 1970
England
Seattle: I-5 and others completed in 2010
Minneapolis: I-35W completed in 2010 and I-94 completed in 2012 Planning stages: • Georgia • Oakland area: I-80 • Virginia: I-66 to be completed
in 2015

Preferential Lane Shoulder
Travel only Emergency use
Reserves for future use Hard to “take away”
Buffer double line – full speed allowed
Single striped line – speed differential
What about State Police and Maintenance?

Benefits
27
ATM Enhances roadway safety: 11% percent – WashDOT
Facilitates transit: Tollway will manage PACE bus on shoulder
Improves mobility: 3 to 7 % increase throughput (Europe)
Enables demand management: speed harmonization
WIM: increased enforcement potential
Full camera coverage: Improved Incident Response and Management
Reduced monitoring patrols
Enhanced traffic monitoring, increased reliability of IT, queue management reduces mainline delays
