A lovely photographic, philosophic, and scientific look at the mechanics of walking and at the ordinary city street corner…where pedestrians and traffic meet, pause, change course...where life happens. Observations and computer modeling illuminate a million mundane interactions of crowds: i.e. There are perennial slow-downs of crowds upon approaching stairs, as people pause -- to check their phones before mounting. Pedestrian traffic on a cold winter day is 35% faster than on a mild summer day. When people step onto a non-moving escalator, they still experience a “sway”—and adapt their gait. At subway stations, escalators don’t actually improve efficiency -- and when people choose to walk on an escalator, the capacity is,counter-intuitively, decreased. Fascinating article with important implications as cities become ever more congested; see how it checks out next time you’re strolling down the sidewalk…
