Parking Is Hell: A New Freakonomics Radio Podcast
Our latest Freakonomics Radio podcast is called “Parking Is Hell.” (You can subscribe at iTunes, get the RSS feed, or listen via the media player above. You can also read the transcript here; it includes credits for the music you’ll hear in the episode.)
The episode begins with Stephen Dubner talking to parking guru Donald Shoup, a professor of urban planning at UCLA and author of the landmark book The High Cost of Free Parking. In a famous Times op-ed, Shoup argued that as much as one-third of urban congestion is caused by people cruising for curb parking. But, as Shoup tells Dubner, there ain’t no such thing as a free parking spot:
SHOUP: Everybody likes free parking, including me, probably you. But just because the driver doesn’t pay for it doesn’t mean that the cost goes away. If you don’t pay for parking your car, somebody else has to pay for it. And that somebody is everybody. We pay for free parking in the prices of the goods we buy at places where the parking is free. And we pay for parking as residents when we get free parking with our housing. We pay for it as taxpayers. Increasingly, I think we’re paying for it in terms of the environmental harm that it causes.
Shoup’s recommendations have inspired a series of reforms across the country, most notably an ongoing experiment in San Francisco called SFPark. The project essentially establishes a dynamic market for street parking by measuring average occupancy on each block and then setting prices according to demand.
While the experiment is exciting for transportation scholars, it has attracted some criticism. Furthermore, one of Shoup’s former students has uncovered a snag that could undermine the project – or any attempt to manage parking more efficiently. Michael Manville, a city planning professor at Cornell, and co-author Jonathan Williams found that in Los Angeles, “at any given time almost 40 percent of vehicles parked at meters are both not paying and not breaking any laws” (paper here, and a Shoup op-ed here). How can that be? Very often, those cars display a handicapped placard that allows for free, unlimited parking. So you’ll hear about “placard abuse” and what’s being done to stop it.
There aren’t yet enough data from SFPark to know whether the experiment helps with congestion, pollution, and accident risk, but Shoup is hopeful:
SHOUP: If it works, it will make San Francisco an even better place to live and do business and visit. It will just be yet another feather in the cap of San Francisco. And if it doesn’t work, they can blame it all on a professor from Los Angeles.
You’ll also hear from MIT professor Eran Ben-Joseph, whose book ReThinking a Lot: The Design and Culture of Parking offers solutions to improve the prototypical parking lot. He gives us a sense of how many surface parking spaces there are in the U.S. (close to 800 million) and points out that in some cities, parking lots cover a full third of the land area downtown.
