How would you determine the "efficiency" of the highways versus straight-line? If I divide driving miles versus straight line, I get 747/617 = 1.2107, so I could say that there's a travel excess of 21.07%,
On the other hand, 617/747 = 0.8260, so the straight line is 82.6% of the driving distance, so I could say that the road layout "inefficienty" is 100% - 82.6% = 17.4%.
Is one preferable to the other? Or is there a third method?
