City Traffic Pro is a complete, flexible, and performance-optimized traffic AI system for Unreal Engine 5. Simulate realistic vehicle movement on roads, intersections, and highways with dynamic behavior like lane switching, parking, and obstacle avoidance. Whether you’re making open-world games, cinematic sequences, or traffic simulations, City Traffic Pro gives you fine-grained control over car AI, flow density, and vehicle management.

📃 City Traffic Pro Documentation

  • Realistic, Scalable Traffic System – Populate any city, town, or highway with vehicles that follow spline-based roads. Supports lane changes, yielding, honking, intersections, and roundabouts. Vehicles maintain road speed while being cautious of vehicles ahead, red lights, and main road traffic.

  • Multi-Lane Roads & Intersections – Easily build traffic on complex road networks using built-in blueprints for roads, intersections (signalized, mid-block, all-way stop, priority, roundabout). Traffic lights are fully customizable, with support for European and American styles and light sequences.

  • Lane Switching & Traffic Flow Control – Blueprints like BP_Change_Lane and BP_Road_Switcher let you guide specific, random or all cars between lanes or roads, trigger lane merges, and handle highway entries/exits. Each control supports probability, delays, specific car support and directional rules for flexible setups.

  • Drivable Cars & Vehicle Integration – Includes 12 fully drivable cars with brake lights, blinkers, engine/tires/horn sound, and damage, plus static versions for parking. System works with many drivable vehicles from Fab.

  • Parking & Stop Control – Create roadside parking, parking lot, or dynamic parking where cars drive in, stop, and later leave. Use BP_Stop_Here to make vehicles pause temporarily or permanently. Static parking lots can be quickly populated using lightweight physics-enabled meshes.

  • Dynamic Spawning & Density Management – BP_Vehicle_Manager spawns, teleports, and recycles vehicles around the player, keeping traffic flowing without performance drops. Set spawn density, night-time traffic levels, vehicle types per road, and define spawn/visibility radiuses.

  • Obstacle Avoidance & Performance – Vehicles detect and avoid other cars and static objects using line traces. Features include configurable aggressiveness, lane-changing obstacle avoidance, and stuck vehicle recovery. Optional “Try to go around” and honking behavior included.

  • Seamless Day-Night Integration – BP_Day_Night_Cycle rotates the sun, controls streetlights and car lights. Traffic density automatically drops at night.

  • Designed for Performance – City Traffic Pro is optimized to support hundreds of vehicles simultaneously. Every blueprint and function is profiled and optimized.

  • Extensive Debug Tools – Visualize spline speeds, vehicle steering targets, avoidance traces, spawn traces, teleport arrows, and vehicle counts.

  • Demo Cities & Road Creator Integration – Includes a demo level with three pre-built cities showcasing different traffic layouts (European, American, British). Seamlessly integrates with Road Creator Pro and other spline-based or landscape roads.

Pack included: Basic EU & US Road Signs (Road Signs documentation)

Pack includes everything you need to create traffic system:

  • 12 drivable cars, which can be used separately from traffic system

  • 12 static car meshes

  • BP_Parking to distribute static car meshes on big parking lot or roadside

  • BP_Road to create multi-lane road spline for cars to follow

  • BP_Intersection to create various types of intersections: signalized, all-way stop, priority

  • BP_Vehicle_Manager to spawn vehicles and keep them around player location

  • BP_Change_Lane, BP_Do_Not_Change_Lane, BP_Road_Switcher, BP_Stop_Here for traffic flow control

  • BP_Roadside_Parking to enable vehicles to drive in and out of parking

  • BP_Day_Night_Cycle to control traffic amount and lights throughout the day

  • Road Creator Minimal – set of blueprints and assets to build various roads. This is very simplified version of Road Creator Pro (less props, road parts, simpler materials) and is used for demonstration purposes.

  • Basic EU & US Road Signs – 74 most popular signs from North America and Europe

  • Demo level with working traffic in three cities
