How does a human (humanoid) travel across the Death Star, which is way bigger than any of the Imperial Navy Vessels (Death Star I was 120km in diameter, DS2 was even larger - 200km). Let us say that an officer is ordered to travel to another sector to check on workers activity there. How can this be achieved in a reasonable amount of time?
I do not remember seeing any lifts, trams or anything like that in the movies, but perhaps it is covered in the books?
Legends or Canon answers are accepted.
