City Traffic System

About City Traffic System – Unity Editor Tool & Plugin

Unity City Traffic System

City Traffic System provides procedural and randomized city generation alongside AI systems for cars and pedestrians, plus a traffic lights system. The package is intended for creating city environments through an automated generation workflow rather than manually assembling every part of the city.

City Generation and AI

The procedural city generator can create randomized city layouts, while the Car AI System and Pedestrian AI System provide separate AI functionality for vehicles and pedestrians. A Traffic Lights System is also included, giving the package three distinct gameplay and simulation components for populated city scenes.

Installation and Setup

The supported configuration is Unity 2021.3.15f1 with HDRP. Built-in Render Pipeline and URP are not compatible. HDRP can be installed through the Unity Registry, although the package can also work without HDRP if its materials are reimported.

Installation also requires the AI Navigation plugin developed by Unity, identified as com.unity.ai.navigation. The setup process includes replacing the project's ProjectSettings files with the ProjectSettings folder supplied in the package. After installation, the Sample Scene can be opened to generate a new city or run the scene directly.

Use Cases

• Procedurally generated city environments where randomized layouts are part of the workflow.
• Projects requiring both car and pedestrian AI within a generated city.
• City scenes that incorporate traffic lights alongside vehicle and pedestrian activity.
