Adrian Short (@adrianshort) sent an FOI request for flow data for the first million journeys on the Barclays Cycle Hire bike shares in London (the “Boris Bikes”). TfL responded with a test dataset of the first 99 journeys -from roughly 6-7am on 30 July – and a promise that the data for the next 999,901 are coming!
I’m working on an adaptation of my bike share visualisation to show these flows. It’s not possible to show a million lines on the screen at the same time, so consolidation, selection and filtering will be applied, but it certainly is possible to show the first 100 – click on the graphic for a full-size image:
I’m using colour to indicate the direction of travel (see the wheel.) I’ve also shown the flows to a couple of specific docks:
I’ll build out the visualisation with the full data set and release it soon.
As start and end timings are included in the data, I’m sure it is only a matter of time before someone builds a version with little animated bikes moving from the stations into the city during the rush-hour, similar to Matthew Somerville’s excellent real-time tube visualisation, for which the underlying data unfortunately got pulled.
