Traffic Engine - Vehicle

100% Real Physics. 100% DOTS Performance. Built for Scale.

Traffic Engine - Vehicle delivers authentic Unity.Vehicles physics simulation built entirely on Unity's DOTS architecture. Experience genuine vehicle dynamics with suspension, tire physics, and realistic steering — all running through ECS, Burst-compiled jobs, and native collections for exceptional performance at any scale.

Physics Implementation
- Full Unity.Vehicles integration with real suspension and tire grip dynamics
- Physics-based steering that responds naturally to road curves and conditions
- Genuine vehicle mass, acceleration, and braking characteristics
- Kinematic fallback mode for distant or lower-priority vehicles, selectable per prefab

Enterprise-Grade DOTS Architecture
- Built from the ground up with Entity Component System for maximum efficiency
- Job System and Burst Compiler integration for multi-threaded performance
- Handle thousands of vehicles simultaneously with smooth framerates
- Memory-efficient blob assets for 10,000+ lane networks
- Four-tier LOD system with frustum culling and per-entity importance bias

Sophisticated AI Systems
- Intelligent perception system with vehicle-to-vehicle awareness using spatial hashing
- Dynamic lane changing with gap detection, turn signals, and smooth transitions
- Multi-strategy obstacle avoidance with emergency braking and dynamic classification
- Predictive speed control for curves and intersection management
- Dual-strategy stuck detection with automatic respawn recovery
- Realistic lateral lane positioning — vehicles gradually converge toward lane center naturally

Audio & Visuals
- Pooled audio system with proximity-based source assignment and speed-modulated pitch/volume
- Full lights system: headlights, brake lights, turn signals, hazard lights, and reverse lights
- Optional animated driver character integration via the Animecs add-on

Developer-First Design
- Public Burst-compatible API for simulation control, vehicle state queries, lane queries, and obstacle tagging
- Centralized debug visualization system with per-category toggles (zero overhead in release builds)
- Scene Validator window, custom authoring inspector, and editor tools for fast setup
- All components and systems are public and designed to be queried or extended without modifying internals

Traffic Engine - Vehicle depends on Traffic Engine - Core (included, separate package) which provides the LaneGraph ECS integration and LOD system — automatically installed as a dependency.

Note: Assets shown in promotional videos are not included. Traffic Engine provides the traffic simulation system only.
