CASA: Pulse of the City » Simulacra: "The visualisation … shows how some links in the [TfL] network are particularly heavily-loaded at various times of the day because of the way that people are travelling around the network based on the probable shortest path that they would take between points A and B. In other words, if someone boards the Tube at Bethnal Green at 9am and exits at Shepherd’s Bush then, in all likelihood, they have travelled along the Central Line and the map below would increment the counter for each segment in the 9am time interval between stations by one. Summing up over all travel for working days produces this time-based visualisation."
