1 Key Issues: OUTLINE What are Managed Lanes? Where Are Managed Lanes Nationwide Key concerns about Managed Lanes Benefits of Managed Lanes
3
2 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)

3 Managed Lanes Projects, 2011

4 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

5 Typical Concerns about Managed Lanes “Lexus Lanes” “Paying twice” Discouraging carpooling Rights of way, adequate room
7
6 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)

8 “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
9 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.

11 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! 13

15 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.
