The three boxes being a box to hold motive power, a box to hold people, an a box to hold cargo, usually arranged in that linear order, with the size ratios depending on the actual function.
Bit of a side track here, but I would think for a future/alien/alternate history world, roads might just not have happened, or (as Waldonrate stated) survived.
