Gone Parkin

Don Shoup's op-ed in the Friday New York Times reminds me of something. While not in downtown proper probably, I think there should be 7 day meters on the National Mall, and in places like Dupont Circle and Georgetown. Probably other places too.

From the article:

Several studies have found that cruising for curb parking generates about 30 percent of the traffic in central business districts. In a recent survey conducted by Bruce Schaller in the SoHo district in Manhattan, 28 percent of drivers interviewed while they were stopped at traffic lights said they were searching for curb parking. A similar study conducted by Transportation Alternatives in the Park Slope neighborhood in Brooklyn found that 45 percent of drivers were cruising.

When my students and I studied cruising for parking in a 15-block business district in Los Angeles, we found the average cruising time was 3.3 minutes, and the average cruising distance half a mile (about 2.5 times around the block). This may not sound like much, but with 470 parking meters in the district, and a turnover rate for curb parking of 17 cars per space per day, 8,000 cars park at the curb each weekday. Even a small amount of cruising time for each car adds up to a lot of traffic.

Over the course of a year, the search for curb parking in this 15-block district created about 950,000 excess vehicle miles of travel — equivalent to 38 trips around the earth, or four trips to the moon. And here’s another inconvenient truth about underpriced curb parking: cruising those 950,000 miles wastes 47,000 gallons of gas and produces 730 tons of the greenhouse gas carbon dioxide. If all this happens in one small business district, imagine the cumulative effect of all cruising in the United States.

What causes this astonishing waste? As is often the case, the prices are wrong.
