AstarIT Traffic

Deterministic road-traffic microsimulation for Unity developers: Nagel–Schreckenberg cellular automaton, engine-agnostic C# core, and 3D visualization of intersections, signals, and multi-type vehicles.

AstarIT Traffic — Deterministic CA Traffic Simulation

What it is

AstarIT Traffic is a software product line of Astar IT — not a one-off client demo. It ships as an embeddable C# library (netstandard2.1) with a Unity adapter for interactive 3D scenes.

Built for English-speaking Unity and simulation teams worldwide. The Unity Asset Store is the primary distribution channel.

Who it is for

  • Unity game and simulation developers
  • Studios building trainers and digital twins
  • Teams that need deterministic, seed-reproducible traffic runs
  • Projects that need a lightweight alternative to desktop transport suites

Core capabilities

  • Nagel–Schreckenberg cellular automaton with intersection extensions
  • Lane changes, traffic lights, multi-type vehicles
  • Engine-agnostic C# core with unit tests outside Unity
  • Unity runtime for 3D visualization and demo scenes

Частые вопросы

What is AstarIT Traffic?

A deterministic road-traffic microsimulation library for Unity, built by Astar IT.

AstarIT Traffic is an Astar IT product line: an engine-agnostic C# core (netstandard2.1) with a Unity adapter for 3D visualization of intersections, traffic lights, lane changes, and multi-type vehicles.

Where can I get the asset?

On the Unity Asset Store (preview listing while publication completes).

Product listing: https://assetstore.unity.com/preview/395076/1424000. The canonical product page is https://astar-it.com/astarit-traffic.

Who is it for?

Unity developers, simulation studios, and research teams worldwide.

Primary audience is English-speaking game and simulation developers who need embeddable traffic microsimulation — not a heavy desktop transport-planning suite.

How does it compare to PTV Vissim or AIMSUN?

Same design-stage modeling class of problems, different delivery format.

Professional tools like Vissim and AIMSUN are full desktop systems. AstarIT Traffic is a lightweight C# library with Unity visualization for trainers, digital twins, and interactive demos with deterministic seed-based runs.

What model does it use?

Nagel–Schreckenberg cellular automaton with intersection extensions.

Includes slow-start, spatial anticipation, probabilistic lane change, intersection maneuvers, and phased traffic-light barriers. Core rules are unit-tested outside Unity.
