Mobile Traffic System - High-Performance Vehicle AI for any platform.
Create realistic, dense urban traffic with 300+ cars running smoothly on mobile. Zero coding required.
Nominated for Best Development Tool at Unity Awards 2021.
Why Mobile Traffic System?
Mobile Traffic System is the only Unity traffic asset that combines mobile-grade performance with production-ready intersection intelligence — roundabouts, zipper merges, emergency vehicle priority, and truck with trailer support, all without writing a single line of code.

🚦 Upgrade to the Full City Ecosystem!
Check out the Complete City Traffic & Pedestrian System bundle.
It combines this advanced traffic system with our high-performance pedestrian engine.
Because they share the same architecture, your pedestrians will automatically use crosswalks, check traffic lights, and stop for incoming vehicles right out of the box.

⚡ Performance & Optimization
- Tested Mobile Benchmark: Smoothly runs 300 cars on a mid-range 2018 Android device.
- Parallel Job System: Powered by a specialized job structure driven entirely by the Unity Burst Compiler.
- Pure raycast physics: Eliminates heavy Unity Wheel Colliders for significantly lower CPU overhead.
- Grid Pooling: Dynamically manages vehicle pools around the player for seamless open-world scaling.
- Pooled Vehicles: Keep specific vehicle pools uninstantiated and activate them via script exactly when needed.
- Optimized Navigation: Ultra-fast waypoint processing prevents pathfinding bottlenecks.
- Universal Scalability: Works flawlessly on any platform that supports the Burst Compiler.
- Future-Proof: Requires Unity 2021.3 LTS or above — compatible with Unity 6.

🛣️ Intersection & Road Behavior
- Traffic Light Intersections: Full support with automatic smart braking and stop logic.
- Priority Intersections: Vehicles independently decide whether to wait, yield, or enter.
- Street Crossing Support: Integrated pedestrian crossings with or without traffic lights.
- Roundabout Intelligence: Vehicles wait until the roundabout is clear before entering.
- Narrow Road Handling: Vehicles wait for the oncoming lane to be free before merging or passing.
- Complex Give Way: Force side-road traffic to monitor designated main-road waypoints, ensuring vehicles only merge when the oncoming lanes are entirely clear.
- Zipper Merging: Vehicles take turns advancing when a multi-lane road converges or narrows.
- Speed Routes: Apply global or lane-specific speed limits across any custom area of your scene.
- Zone Restrictions: Categorize vehicles (e.g. sedans, trucks, special-purpose) and restrict access by type or zone; force heavy trucks to outer lanes only or block them from entering city centers entirely.

🧠 Vehicle Intelligence
- Overtake & Lane Selection: Vehicles automatically check adjacent lanes and safely pass slower traffic. Lane changes can also be triggered via the API.
- Emergency Vehicle Priority: Traffic actively pulls over and clears the way for ambulances or custom emergency vehicles.
- Building Avoidance: If a vehicle accidentally collides with static environment colliders, it attempts to recover autonomously.
- Variable Wheel Support: Scales perfectly from 3-wheel setups to heavy multi-wheel configurations.
- Customizable Properties: Easily tweak acceleration, max speed, brake speed, steer angles, and more per vehicle.
- Truck & Trailer Support: Full articulated truck behavior out of the box.
- Natural Lane Offset: Vehicles no longer drive perfectly centered; a subtle, realistic offset is applied automatically.
- Custom Behaviors:
