The everyday in a metropolis like London involves constant movement among its citizens. Using private information collected from passengers' use of Oyster transit cards, transportation planner Jay Gordon has mapped a day of travel for 3 million London commuters. The Oyster data was provided by Transport for London for researchers at MIT, recording where people swipe their card to enter or get off a bus or the Tube. Gordon uses green dots to represent commuters currently on the move on a bus or train, blue dots to show where they begin and end their day—probably their homes, and red dots to signify those between trips on public transit. Using algorithms to predict some activity, the data was compiled into a visual time-lapse animation of a full 24-hour cycle beginning at 3 AM on a regular Wednesday in London in 2011.
