It's a traffic AI system with a lot of intuitive controls and easy to set up blueprints. One-click actor placements and initialization. You can basically make a working traffic system in less than half an hour. Currently, it is not made for open-world setups but automatic spawning and de-spawning coming with the next update soon.

NOTE: Please Check out this tutorial here or go through the documentation before working with the blueprints, otherwise you may feel lost and don't forget to spam that Assign Roads editor event in the ROAD BOSS BP before playing a map.
