I wonder whether the Oxford Circus crossing is actually just an attempt to reduce the number of pedestrians walking around the outside edges of the junction - it's pretty disorientating coming out of the Tube and not knowing which corner you're on, and the entrances seem to get in the way of pedestrian traffic trying to cross non-diagonally.
