Visualising Bike Share (#geomob 21 October 2010)

5,239

Published on

From Boris Bikes in London to Bike Share across the World. Introducing, visualising and analysing bike share schemes in Europe, America and Asia, including London's Barclays Cycle Hire, Montreal's Bixi, Barcelona's Bicing and Paris's Velib. Who's using them, when are they using them and what do the schemes look like?

  • The picture is of the T-shirt that was given out to the first 1000 people that signed up for the scheme in London.
  • Fully automated, including sign-up and operation. However London, at least, employs workers at some of the stations at rush-hour to provide extra capacity (bikes in the morning, spaces in the evening). This is a short term measure. Waterloo will shortly get 350 docks which should alleviate this problem.
  • This is a familiar scene to commuters leaving the terminal stations in the morning, or leaving the City in the evening...
  • Above: Minneapolis “Nice Ride”. Below: Barcelona “Bicing”
  • http://www.denverpost.com/election2010/ci_15673894
  • The cities are at roughly the same scale (exactly the same zoom level, which = scale * cosine (latitude))
  • Screenshot of empty bike stations in west Barcelona at 9pm on Wednesday.
  • Note this is just one day’s worth of data – and doesn’t control for weather conditions or special events.
  • Note this is just one day’s worth of data – and doesn’t control for weather conditions or special events.
  • London, Dublin and Brussels have a slightly earlier evening peak than Milan and Paris. Vienna doesn’t use the scheme to commute.
  • Use at lunch is as much as (or more than) during the evening rush hour, and the evening peak occurs at around 7pm – the Spanish “siesta” working pattern”. Girona is very small, so usage rises gradually during the day, rather than having a morning rush hour.
  • Denver doesn’t have the rush hour peaks – showing that few commuters are using the scheme, possible due to the U.S car culture?
  • Usage in general much lower than during the week, and mainly late afternoon use, particularly in Paris and Milan.
  • Spain still has a siesta at the weekends! (The effect is noticeable in four of the five Spanish cities included.) The bikes also get used all through the evenings.
  • Higher usage at the weekend than during weekdays, in the US.
  • Comparing world city dynamics based on bike shares!

    12. 12. Denver – Conspiracy • “Republican gubernatorial candidate Dan Maes is warning voters that Denver Mayor John Hickenlooper's policies, particularly his efforts to boost bike riding, are ‘converting Denver into a United Nations community.’ “Dan Maes said Denver's B-Cycle bike-sharing program was promoted by a group that puts the environment above citizen rights.” – article in the Denver Post Source denverpost.com, photo CC-By-NC Trace Altman on Flickr
