This is my current transportation breakdown for the Asia 2017 trip. The total comes to $1,698.22, or $19.98, a day for all transportation from one location to another for the 85 days. While that will not be the exact final figure but it will be fairly close as the airfare and bus rides are already purchased and that comprises the vast majority of the major transportation expense. There are 23 flights, 3 bus rides, 3 train trips and a car rental. Actual map is here.
