STS Tools Window
Available to help automate and reduce the amount of work required when configuring routes for large road sections or networks; these reduce the need to manually select waypoints in the scene hierarchy to make configurations.
Select Tools > Simple Traffic System > STS Tools Window from the Unity menu bar to open the Simple Traffic System Tools window. This window contains a variety of editor tools that can be used to create your simulation.
Note: The asset can be used without the tools window by manually assigning the relevant references to AITrafficWaypoints, however the window enables you to use a variety of editor scene tools to make creating and customizing your waypoint routes and waypoint connections much easier.
