One side is for the standers and the other side is for the walkers.

一边是给站立者，另一边是步行者。

Escalator walkers and standers have learned to accommodate or at least tolerate each other.

在扶梯上的步行者和站立者学习着互相提供行动空间，或至少可以彼此容忍。

A walker takes up an average of three steps while a stander takes up just one.

步行者平均可以走到 3 个阶梯，而站立者只占 1 个阶梯。

The bad stander who benefits directly or indirectly and acts as a puppet for the bad actor?

是那个直接或间接受益、充当反面角色傀儡的同谋？

It's a delicate balance that's been struck, forced out of a battle between the walkers and the standers, that's been going on as long as escalators have been around.

这是一个微妙的平衡，被迫带出了行走和站立者间的争执，同时随着扶梯的存在而一直持续着。
