Back at the end of 2015, the Transport for London (TfL) — the agency that oversees public transit in the city and cautions everyone to mind the gap — decided to disrupt the natural order of things for three weeks and instructed hurried London commuters going up and out of Holborn Tube Station (about a 77-foot journey) if they could stand on both sides of escalator. As this Guardian article about the experiment points out, this is a huge violation of British social norms, and the Brits do really love their social norms. Knowing that, TfL planted folks in the walking path on the left and asked any couples in the queue to stand next to each other and hold hands, all the better to thwart walkers.
The whole experiment proved two things. First, commuters were not happy with the new process, but after three weeks, they grew a bit "docile." Second, it was much, much more efficient for people to stand side-by-side up the escalator. In fact, an escalator that normally carried 12,745 people up to the street between 8:30 a.m. and 9:30 a.m. brought up 16,220 in the same hour with people standing side-by-side.
That is almost 3,500 more people in an hour who got out from underneath London and on their way to their destination sooner than they would have with the split-use escalator.
Malaysians more advanced.. We knew it all before them. Ang mohs did any such experiments
