Key Issues: OUTLINE

What are Managed Lanes?

Where Are Managed Lanes Nationwide

Key concerns about Managed Lanes

Benefits of Managed Lanes


What Are Managed Lanes?

Specialized, rather than General Purpose, lanes

Variable pricing, to keep traffic flowing uncongested

Usually limited to cars, vans, buses

Two ways to create:

– Conversion of under-performing HOV lanes – Creation of new lanes (added capacity) 2

Managed Lanes Projects, 2011


Managed Lanes Networks

In Long Range Transportation Plan already:

– Atlanta – Dallas – Houston – San Diego – San Francisco – Seattle 

Being considered:

– Los Angeles – Miami-Dade/Broward/Palm Beach Counties – Washington, DC 4

Typical Concerns about Managed Lanes

“Lexus Lanes”

“Paying twice”

Discouraging carpooling

Rights of way, adequate room


The “Lexus Lanes” Issue

Data on commuter attitudes (San Diego, Seattle)

Data on usage (91X, I-15, I-394, SR 167)

  High income uses somewhat more frequently But all economic sectors use lanes at least some times when the need to  Women slightly more likely to be users 

Win-win (GP lanes benefit, too)

Common-sense comparisons (restaurants, airlines, Amtrak, Postal Service)


WSDOT Data on Managed Lanes Usage


“We’ve Already Paid For These Lanes”

Usually applies only to conversions

Best answer: HOV-2 not working well

 If empty lanes, taxpayers not getting full value from expensive pavement.

 If congested, motorists aren’t getting promised benefits.

If new capacity, the money is seldom there for new GP lanes, or concerns they will simple become congested quickly.


Do Managed Lanes Decrease Carpooling?

No evidence of carpooling decrease

Significant increase on I-15 MLs in San Diego

Conversion definitely reduces violators

Inevitable shift from HOV-2 to HOV-3 in congested corridors might reduce carpools in the ML itself.


Rights of Way/Room to Expand

Tampa’s elevated reversible express toll lanes—6 lanes in 6 ft

Benefits of Managed Lanes

Optimize use of all roadway capacity

Increase throughput compared with GP lanes during peak periods

Enables Bus Rapid Transit

More choices for travelers (“congestion insurance”)

Reduce emissions of increase travel

Expand economic opportunity

Generates revenue to pay at least part of costs

Widespread public and political acceptance.


Current long-range transportation plans don’t reduce congestion

I-95 Miami Managed Lanes: A real success story by any measure

Daily toll traffic now exceeds 50,000 paying vehicles

 20% of total daily traffic (higher in peaks) 

Annual revenue tracking at about $18-20 million

 Phase I only; southbound direction only opened for 5 months  Strong return on project that cost less than $100 million to convert… including toll systems and dynamic signing 

Express Lanes above 45 MPH over 99.5% of the time

Cut overall average peak period travel times in half for all users, and by two thirds for Express Lane users!


Impacts on Peak Period Speeds and Travel Times Travel Speeds (Northbound - PM Peak Period) Before Conversion After Conversion Travel Time (Northbound Peak Period) Average Peak Period Time Savings = 14 Minutes


Synergy of Managed Lanes and Bus Rapid Transit (BRT)

Value-priced lane is virtual equivalent of an exclusive fixed guideway.

Pricing limits vehicle flow to what’s compatible with LOS C conditions.

Reliable high speed is sustainable long-term, thanks to pricing.

Miami has implemented on new I-95 Express Lanes.

S.F. Bay Area planning regionwide express bus on its HOT Network.

Economic Benefits of Atlanta’s ML Network (2030) Travel Time < 45 min.

91 Express: A popular option

 Over 150,000 Vehicles equipped with Transponders  Typically only one in five used in a given day  15-20% of total traffic uses toll lanes  Much higher share in peak hours  Preset Variable toll rate structure  Tolls range from about $1.00 to $10.00 for 10 mile trip  Very high level of public approval

Summary Managed Lanes have a track record of:

Improved Flow and reduced congestion

Improved Bus transit operations

Very popular where they are in place
