How Bike-Share Stations Stack Up Against Other Curb Consumers

Compared to other things eating up parking spaces -- new curb cuts, parking placards -- bike-share will be tiny. Data sources and methodology available in this spreadsheet
Bike-share, no doubt, is going to be a major addition to the streets of New York — in terms of both impact and visibility. Within the service area, there’s going to be a station every few blocks. And some of those stations are going to have a lot of bicycle docks: 59 in many locations, and a whopping 118 next to Grand Central. Thanks to the small footprint of bikes, however, overall this new form of transit will consume relatively little space while allowing people to make tens of thousands of trips per day.
Much of the discussion of bike-share’s size involves the number of parking spots the system will displace, and with the release of the draft service area map last week, it’s possible to estimate how much car parking will give way to bike-share stations. (“How Many Parking Spaces Will CitiBike Share Gobble Up?” went the Gothamist headline yesterday.) But some perspective is in order: Only a fraction of the proposed bike-share stations will remove parking spaces, and those are clustered in neighborhoods where community boards specifically requested that the docks stay off their already-crowded sidewalks.
Of the 420 stations scheduled to open this year, only 157 replace car parking — a little more than one in three. (To run the numbers we used Gothamist’s spreadsheet of Manhattan bike-share locations and added our own count of stations in Brooklyn and Queens slated to replace parking. You can download Streetsblog’s spreadsheet with that information and all the math in this post.) Most bike-share stations are slated for on-street locations that don’t take away parking, on sidewalks, in parks and public plazas, or on private property. That 118-dock station near Grand Central, for example, will be in a no-parking zone of Park Avenue.
More importantly, the bike-share system will provide far more total transportation capacity in that curbside space than automobile parking does. Bike-share will eliminate 623 on-street parking spaces, according to Streetsblog calculations (one parallel parking space takes up around 22 feet of curbside space; bike-share can fit four docks — or three docks and a payment kiosk — in ten feet). In those spots will be 5,320 new bike-share parking spaces: eight and a half times as many.
To put it differently, you could fit a 39-dock station in just five parking spaces. Bikes are simply a lot smaller than automobiles, and the space it takes to store one car can hold a lot more bikes.
The rate of turnover gives bike-share another big advantage over car parking.
