There is a chest high fence that prevents jaywalking from Hojos to DLR entrance and I would not want to be stuck on them fences. The fastes way is to cross at Manchester then walk to the public bus stop. ARound there is a hole in the fence and a legitimate pathway to the taxis and shuttle buses. You avoid the light and save a few steps as the west side of that road way curves west so you actually are walking a bit further than cutting through the shuttle area.
