An integral part of unrestrained car use is having somewhere to put the darn things when we’re not driving them. Enter the “free” parking space.
They aren’t, of course, actually free — thus someone else is paying, not the driver using it, it is external to the cost of driving; call it socialism for drivers. Thus leading to ever more demand for more driving and more parking spaces.
from the Arizona Republic 12/28/2009; Ahwatukee Park-and-Ride Lot Expanding.
In the example mentioned in the story, 353 spaces are being added to the existing 562 for a cost of $3M. That’s $8,500 per space. But that is only the cost of construction (or land but that is cheap); the ongoing costs aren’t listed but they are significant. A not exhaustive list would look something like; lighting, maintenance like sweeping and cleaning, and re-sealing asphalt, full-time(one employee ~ 50hrs/week) security during operating hours, cost of operating the small building (heat and cooled approximately 24×7, even though no one is usually there; didn’t these people ever hear of a programmable thermostat?).
see Doug Shoup’s book mentioned here; The High Cost of Free parking.
In the particular example of a transit park-and-ride lot it gets even more interesting because of the cross-subsidies involved in mass transit. One wonders if the best use of presumably limited transit funds is to build parking spaces for the relatively well-off remote suburban commuters. This lot serves only one bus line; a rapid/express (no intermediate stops) route between Ahwatukee and downtown Phoenix. The line only runs one way, and only in the morning and evening. Thus the parking spots have low turnover — one spot equals one round trip rider.
