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)

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

Typical Concerns about Managed Lanes
“Lexus Lanes”
“Paying twice”
Discouraging carpooling
Rights of way, adequate room
![Page 7: Managed Lanes Overview](https://reader036.vdocuments.net/reader036/viewer/2022062323/56815f05550346895dcdc4c0/html5/thumbnails/7.jpg)
7
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)

“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.

10
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 congestedcorridors 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.

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!

Synergy of Managed Lanes andBus 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.
