Procedurally Generate Zone Graph Roads in UE5 With This PCGEx Addon
This Unreal Engine 5.7 UE5 PCG tutorial shows how to automatically generate Zone Graph traffic roads using the PCGEx plugin, eliminating the need to manually place road splines for traffic systems. By combining UE5’s Traffic framework with advanced PCGEx nodes, we create a fully procedural road network that adapts dynamically to your city layout.
You’ll learn how to use PCG graphs and PCGEx to spawn Zone Graph–compatible roads directly from your procedural city generator, allowing vehicles to navigate automatically without hand-placing traffic paths. This workflow turns static procedural streets into a scalable, traffic-ready system built entirely with Unreal Engine 5.7 and Blueprint-friendly PCG tools.
This is part of an ongoing procedural city generation series in Unreal Engine 5, covering roads, intersections, blocks, parcels, buildings, districts, city population, and now fully procedural traffic systems. These techniques are ideal for open-world games, simulations, and large-scale urban environments built with UE5 PCG and PCGEx.

---------------WARNING------------------
It seems that Fab keeps updating the main PCGEx plugin even when they're not supposed to, and not updating when they should. Which is breaking the connection to the zone graph addon plugin I got. When Tim, the creator of PCGEx, pushes major updates to PCGEx I'll try to get the updated the zone graph addon as well, but that doesn't mean that a random unexpected update from the Fab team won't break it again.
