This diagram looks like what a few ravers might create with glow sticks in a club, but it actually shows the usage patterns of 10 million bike trips taken on London’s bike hire system.
Wouldn’t it be awesome if we had something similar for Auckland? I guess if we had a public bike system (again) first… – but some other cities have done similar geospatial analysis with the help of people volunteering to use tracking apps on their smartphones while riding, so it could be done here too, even if we don’t have “Boris Bikes“.
