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 dayâ€”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.
