The study shows this was better at peak times, especially for the goal of making sure there are no queues at the bottom of the escalators which can slow the tube down, but presumably in normal times (when there is space for standing and walking) this is worse for individuals who have a preference on walking or standing.

I get the tube to and from Holborn every day and there are always people (me included) walking and I rarely arrive at peak times.
