Trafiken är organiserad i 3D-trafikleder, som regleras av en komplex uppsättning regler och poliseras av Coruscant Air Traffic Control (namnet varierar enligt Era).
Ett citat från "Legacy of the Force Book 2 - Bloodline" (Legends continuity)
It was hard to seal off a neighborhood in a place like Coruscant. The intersections were three-dimensional and required six CSF traffic division repulsorlift ships for each skylane junction that Jacen needed to have blocked off. He stood on the platform of a military assault vessel, a matte-gray gunship not unlike its CSF counterpart, watching two of the CSF ships hover into position. It was still dark; the CSF vessels had no navigation lights showing. Jacen could only see them because the light pollution on Coruscant meant that Galactic City was never truly pitch black, and he could pick out the shape of the hull when it moved.
