"The San Francisco Bay Area is building the most extensive network of High Occupancy Toll (HOT) Lanes in the world, something Reason Foundation suggested for San Francisco and other urbanized areas in 2003. The HOT Lanes concept was introduced by the Foundation in 1993.
"Under the current proposal moving forward, 450 miles of existing carpool lanes in nine counties are expected to be converted into HOT Lanes, with tolls varying by time of day and level of congestion. Another 350 lanes will be added later. [...]
"It's not quite privatization, but HOT Lanes are proving to be an efficient, effective, and manageable market-based tool for putting the right infrastructure in the right place at the right time based on the most useful criteria of all: willingness to pay."
