Well, yes, from what everyone has said, it sounds pretty convoluted over there. But I'm saying, perhaps if the pilot(s) had scanned (correctly, not just a cursory glance) before crossing they probably would've seen the other jet roaring towards them.
I was trained to clear left center right before crossing any taxiways or runways even if I had a clearance.. leaves less room for human error.
Maybe the confusing layout/construction did contribute to the near incursion, but how many thousands of planes operate there daily? How are all those other pilots able to avoid such mistakes? To me, this seems more of a complacency issue than a layout problem.. ALTHOUGH, it was probably a combination of everything that added up (pilot error, layout, lack of staffing, etc.)
