HOT Lanes in the Bay Area

The San Francisco Chronicle is reporting that the Metropolitan Transportation Commission (MTC) has approved a plan to allow solo drivers to pay a toll to drive in Bay Area carpool lanes, turning HOV (high occupancy vehicle) lanes into HOT (high occupancy toll) lanes. The article states:

The system would be phased in over nearly two decades, starting in late 2010 or early 2011, and the first pilot projects would open on two congested corridors: southbound Interstate 680 over the Sunol Grade and both directions of Interstate 580 between Livermore and the I-680 interchange, according to the Metropolitan Transportation Commission, a regional planning and funding agency, which is coordinating the plan.

Eventually, the toll-lane network would be expanded to cover nearly 800 of the region's 1,200 miles of freeway lanes.

The price of the tolls hasn't been decided, but it could start out at a couple of dimes per mile. Motorists would use FasTrak transponders to pay.

I'm From the Future

An article today from the Washington Post describes a new infrared system for applications in High Occupancy Toll (HOT) lanes. It explains that

The lanes are billed as the salvation of the suffering commuter. Solo drivers will be able to buy their way around congestion, while carpoolers will ride free. But the lanes' success hinges on finding a way to differentiate between paying and nonpaying customers without stopping every vehicle to count heads.

The system automagically detects the number of passengers in passing vehicles by bouncing infrared waves off of their skin. This marks a departure from computer vision-based approaches for detection in similar circumstances (for example, automated pedestrian detection).

US DOT announces who gets the Urban Partnership money

The U.S. Department of Transportation announced today the five metropolitan areas to whom they awarded the Urban Partnership Agreements (UPAs). The winners are:

• New York
  
• Seattle
  
• The Miami and Ft. Lauderdale metropolitan area
  
• The Minneapolis and St. Paul area
  
• San Francisco

Each of the winners will still need to submit traffic studies for their respective projects before receiving the money. Twenty six cities applied for the the program's funding. New York's $354 million will go towards congestion pricing in Manhattan. Seattle will use its $139 million to charge tolls on the Highway 520 floating bridge. Miami's $63 million will go towards installing variably priced toll lanes on I-95 between Miami and Ft. Lauderdale. Minneapolis will spend use it's $133 million to add High Occupancy Toll lanes to I-35. San Francisco's $159 million will help establish a congestion pricing plan for the downtown area.
