Citi Bike Trips Since Launch

Source: directly reported from the Citi Bike data feed.


Citi Bike Trips Per Day

Source: day-to-day difference in "data feed"-reported "Trips since launch" numbers. As of June 9, these numbers vary slightly from the "data feed"-reported "Trips 5 pm - 5 pm current day" numbers in the May 27 - June 4 timeframe, but have been consistent since then. See the raw data section at the bottom of this page for exact differences.

Citi Bike Miles Per Day

Source: day-to-day difference in "data feed"-reported "Miles traveled since launch" numbers.


Citi Bike Average Trip Duration (minutes)

Source: directly reported from the Citi Bike data feed.


Citi Bike Miles Per Trip

Source: day-to-day difference in "data feed"-reported "Miles traveled since launch" numbers divided by day-to-day difference in "Trips since launch" numbers.


Citi Bike Annual Memberships

Citi Bike Activity by Neighborhood - Activity Per Dock

Source: Citi Bike blog's live station feed, sampled every 2 minutes, aggregated over an entire day. "Activity" is defined as any change in an "In Service" station's availableBikes count (i.e. an increase implies bike returns while a decrease implies bike checkouts) divided by the number of docks. So a neighborhood with 7 docks and samples {availableBikes=4, availableBikes=5, availableBikes=10, availableBikes=2} would have a score of (1 + 5 + 8) / 7 = 2.0.

Thus, this is a measure of how *busy* a neighborhood is over how *popular* a neighborhood is. In other words, if two stations have equal activity but the first station is half the size, then the first station scores twice as high. Stay tuned for graphs showing absolute popularity, too.

Neighborhoods are defined as specific sets of stations, manually curated. Stay tuned for the current neighborhood definitions.

This data is inherently approximate due to limitations in the data shared by Citi Bike's feed. Specifically:
  • If at time t availableBikes=5 and time t+1 availableBikes=5, this could mean there was no station activity or it could mean the same number of bikes were deposited as were withdrawn between those times. This data assumes the former, and thus underestimates activity.

  • This data cannot distinguish between real usage and bike redistribution. Citi Bike workers regularly visit full stations, withdraw bikes en masse into a truck, and redeposit these bikes at empty stations. This would likely appear as, e.g. a change from availableBikes=36 to availableBikes=26 in a small period of time. This data does not identify those scenarios, so in this sense it may overapproximate activity. However, it seems likely that more active stations require more redistribution. So this probably doesn't skew final results.

  • Citi Bike's feed isn't always available. In particular, the feed goes down during "website maintenance" which can occur in early morning hours. As of June 5, 2013 at 9:39 PM, about 9% of all samples are empty (all between 11 PM and 5 AM on various days).

  • This data can only be accurate to the extent that Citi Bike's own data is accurate.

Citi Bike Neighborhood Reports


Activity report cards for each neighborhood, including which stations define each "neighborhood" and top station rankings.




Citi Bike Themed Station Reports


Activity report cards for arbitrary sets of stations grouped by a common theme (e.g.: "stations by major transit centers").



Citi Bike System Supply

Source: Citi Bike's live station feed, sampled every 2 minutes.
  • "In-Service Stations" is the maximum number of stations marked as "In Service" in a given day.
  • "Available Bikes" is from the feed's availableBikes field (number of bikes in a dock and ready to be checked out).
  • "Working Docks" is the feed's availableBikes + availableDocks sum, and approximates the number of docks that are correctly operating.
