Want to Get Out Alive? Follow the Ants – Issue 13: Symmetry – Nautilus

“If you have an exit in the middle of the wall, you can imagine coming from the left side, the right side, and straight,” Shiwakoti says. These different streams of ants, or people, have to merge at the exit and take turns to pass. But people are impatient, and start pushing and shoving. Columns help structure the flow. “The column gives you some channels on the left and on the right, and this reduces the conflict at the exit.” The reason the corner exit is so efficient, Shiwakoti says, is because it has an intrinsic ability to structure the flow. “If the exit is in the corner, then people are probably only coming from left and right, so you have a more uniform flow.”
