Change Log (Updates could take a few days for Epic approval):

2020/09/12

Added Auto-Sync feature to traffic lights.
Fixed function call warning.
Fixed spawn location bug on builds.


Welcome to the Architectural Visualization AI Traffic system. I designed this system to give architectural renderings and real-time rendered scenes a boost of realism by adding movable cars to roadways and intersections. This system also works for virtual reality. Key features are options for spline following, waypoints, spawning vehicles, removing vehicles, parking, turn signal lights, brake lights, head lights, traffic light. The traffic light is included (up to 4 per intersection) with both turning lanes or keeping straight options and can easily swap for a traffic light mesh of your own.


The system is created with a series of blueprints and AI behavior trees for easy modification and customization. Does NOT use NavMash(Pathfinding). Although it is designed for Arch Vis, it is possible to work for games as well, but is untested on gaming platforms. Please view the tutorials below:
