Quoth the article: People used the left elevator more than the right one

This makes me wonder: Did people choose the left elevator; or was there a single-elevator-call button which they pressed, upon which the elevator-control program preferentially dispatched the left elevator? I wouldn't be surprised if the elevator-control program always handled the situation with two equally close available elevators by dispatching elevator #1 rather than elevator #2.

Is anyone here familiar with the Tisch School of the Arts?



The office building I work in has three elevators; my observation has been that when I call an elevator at high-traffic times such as lunch-time or 5PM I might get any elevator while at lower-traffic times I tend to be allocated the left or middle elevator.

My mental model is that an elevator with scheduled destinations (buttons pressed inside) is 'allocated' and an elevator travelling to service a call is 'allocated', while other elevators are 'free'. If you press 'down' and there are no elevators above you going down, or if you press 'up' and there are no elevators below you going up, the left-most free elevator will be dispatched.

It makes sense to wear out elevators unevenly: If two or more elevators were evenly used, it's more likely they'd break down at the same time, leaving your building with no elevators at all.
