Faster and Greener-- Pocket Airports - CAFE Foundation

28 The network of pocket airport infrastructure necessary to realize this model would costonly a fraction of the cost of adding lanes to the existing freeways, which typically cost$20M per mile. These cost savings are even more impressive when compared tosubsidized transit systems, as evidenced by the recent cost of a Bay Area Rapid Transitextension that cost $161M per mile.

Moreover, those traveling inthe SAV would benefit with much faster, gridlock-free commutes compared to thosetraveling in cars. In addition, some of the airport construction costs could be offset by therevenue from renting SAV parking spaces.In San Francisco, as shown in Figure 3 below, the several sites at which pocket airportscould be built would provide excellent walkable access to the city’s major attractions.
