We've gotten questions about how we crunched New York City subway turnstile data for the opening of the Barclays Center. WNYC's senior editor for data news explains all in this post for the station's data news blog, which we've reprinted below.
(John Keefe - New York, NY, WNYC) Saturday morning we did something fun: We counted the number of people who took the subway to the opening-night Jay-Z concert at Brooklyn's new Barclays Center the night before.
Or at least got pretty close.
Traffic and transit were closely watched for the new arena, as the 19,000 or so concertgoers would have just 541 parking spaces. So we decided to grab data from subway turnstiles to measure the crowds leaving the Atlantic Ave-Barclays Center station for the show.
How we did it
Turning around the data overnight took a little planning. Here's how we pulled it off:
Every Saturday morning, the MTA posts turnstile data for the previous week. Fortunately for us, the last reading is 8 p.m. Friday, the scheduled start time for the concert.
The data files contain the entry and exit counter readings for each turnstile in the system as a sort of "odometer" reading. The data is a little tricky to use, though it does have a regular structure.
So Steve Melendez, our Data News Team programmer, wrote some Python code that grabs the data files and puts the individual readings into a SQLite database. He then sorted the readings by station (using this chart), and calculated how many exit clicks were logged for the Atlantic Avenue station from 4 p.m. to 8 p.m.
We suspected there would be a jump in the time period before the concert. So earlier in the week, we ran the numbers for each Friday for much of the year and calculated those averages (I ended up using just September, because they were higher, post-summer vacation readings). Then, Saturday morning, Steven got up really early and ran the program again, including the newly posted numbers.
He sent me the latest values, and I added them to the chart in a taxi on the way to the station. At 8:35 a.m., I was on the air talking about how it appears about a third of the concert-goers took the subway.
It could be more than that. Some people could have left the system at another station. And if anyone left through an emergency exit, or if they showed up after 8 p.m., they wouldn't be in our turnstile data.
But it's a place to start, and we'll be watching how these numbers change for future concerts and for Brooklyn Nets games.

After almost a decade of fits and starts, the first part of the $4.9 billion Atlantic Yards project opens Friday. But the hoopla can’t quell the controversy surrounding the project. Neighborhood groups continue challenging Atlantic Yards, arguing that a Community Benefits Agreement signed by some, doesn’t include or apply to all.

The resignation of Vito Lopez as head of the Brooklyn Democratic Party means that, in a few weeks, Brooklyn Democrats will get a new party chairman. What, exactly, that means and why it’s important can be difficult to understand for those not deeply steeped in the arcane world of intra-party politics.

(New York, NY - WNYC) Several Brooklyn-to-Manhattan commuters were baffled at 7:45 this morning to find an unexpected boarding ritual taking place at the head of the gangway leading to their ferry. Mayor Michael Bloomberg and City Council Speaker Christine Quinn, a likely candidate for mayor, stood there waiting to shake hands.
"Congratulations!" Quinn told the riders, one by one. "You're among the million passengers to take the East River Ferry!"
That's a million paid customers in just over a year, more than double the initial projection of 409,000 annual riders. But that success comes at a price to the city: a $3.1 million subsidy per year over the three-year life of the pilot program.
The money comes from the city's Economic Development Corporation. Private ferries that criss-cross the Hudson River, connecting New Jersey to various parts of the harbor, do not receive subsidies.
The East River Ferry started with 12 days of free service last June. From the beginning, it proved popular with New Yorkers and tourists. The boats follow a route that goes from Wall Street to East 34th Street in Manhattan with stops along the way -- four in Brooklyn and one in Queens. Then they ply the trip in reverse. (Bloomberg and Quinn boarded at the North 6th Street stop in Williamsburg, Brooklyn for a three stop ride to Wall Street.) In spring and summer, the ferry adds a Brooklyn harbor loop and makes the short hop from Lower Manhattan to Governor's Island.
Weekend service is especially popular in the warm months. Billy Bey, the company running East River Ferry, says it has had to operate larger vessels on the weekends to hold the crowds, and a new landing at Brooklyn Bridge Park has been fitted with wider gangways to speed boarding and disembarking.
The ferry isn't cheap: $4 for a one-way trip, compared to the $2.25 base fare per subway ride with a Metrocard; and the ferry charges $140 for a monthly commuter pass, compared to $104 for a 30-day unlimited ride MetroCard.
But sometimes a passenger like Bloomberg can catch a break. The mayor ordered a $2 cup of coffee from the on-board concession stand, which a woman who gave her name as Jennifer served up gratis. Jennifer said she was happy to do it "because he's the mayor," although she initially called him Mayor Giuliani. But Jennifer also noted a Bloombergian particularity: the mayor added milk to his Joe but, true to his crusade against empty calories, no sugar.

(Janet Babin -- New York, NY, WNYC) Residents concerned about traffic and congestion around the new soon-to-be-opened Barclays Center arena in Brooklyn have until Tuesday, July 3, to submit written comments to Empire State Development, the state agency overseeing the project.
“These streets will just be absolutely clogged with on street parking, and the [transportation plan] doesn’t address that,” Gib Veconi said. He is with the Prospect Heights Neighborhood Development council and complained there will be a lack of on-street parking for the thousands who will drive to shows at the arena after it opens this fall.
According to surveys conducted by the project’s developer, Forest City Ratner, about 2,500 carloads are expected to drive to each Barclays Arena event — and there are 220 events so far scheduled at the arena during its first year in operation.
Empire State Development extended the comment period to give residents more time to respond. ESD said it’s confident that the neighborhood will be able to absorb the influx of visitors because many will take public transportation to the Prospect Heights facility.
“The goals of the transportation plan are to reduce the number of cars traveling to the arena and to maximize the use of mass transit. We are confident the plan will be effective,” explained Arana Hankin, ESD’s Director for Atlantic Yards.
Hankin said even after the comment period closes, residents will have other chances to tell ESD if transportation or other issues arise.
ESD, the Borough President’s Office and Forest City Ratner are establishing a Quality of Life Committee comprised of community members to address the arena's sticking points.
Hankin said Forest City Ratner is also hiring a full-time community affairs staffer to handle local concerns regarding all aspects of arena operations.
But Veconi said he will continue to push officials to create residential parking permits to reserve on-street spaces for residents. Residential parking permit programs, however, need permission from the state.
