Traffic Controllers

Traffic Controllers manage traffic signals within a junction by grouping multiple traffic lights under a single controller. They define which signals belong to a specific junction, making it easier to organize, monitor, and coordinate signal behavior and timing.

Open the tool from the Signals toolbar, then work in the Controllers panel on the right.
