It would also help if LUL were consistent in their signage, not only on
one-way systems. Some staircases are labelled 'Keep Left' (ought to be
obvious), some are labelled 'Keep Right' and most are not labelled at all!

The worst ones tend to be when the normal up escalator is taken out of
service and the down is switched to up running. I've seen many a collision
at Bank/Monument because on the escalators is running the wrong way to
everything else, and everyone in the long corridors is sticking to the side
of the esclator they've just come off.
