MTR Traffic Addon generates road traffic in Minecraft Transit Railway worlds.

Place traffic spawn and despawn connectors, manage routes through the Traffic Dashboard, and let vehicles drive through your MTR-based road network.

For example, if you have built bus networks using MTR and custom resource packs, you can now generate realistic car traffic, manage intersection traffic lights, and bring your roads to life.


Features

  • Traffic Spawn and Despawn Connectors
  • In-game Traffic Dashboard
  • Vehicle pool selection per spawn point
  • Intersection areas with signal phases
  • Vehicle spacing, queueing, and MTR vehicle awareness
  • built-in sedan models (MTA Mesh Sedan with 8 color variants)
  • built-in hatchback models (MTA Mesh Hatchback with color variants)

Important Information

  • Requires Fabric, Fabric API, Minecraft 1.20.1/1.20.4/1.21.1, and MTR 4.0.4 or newer
  • You can run it's fabric files on forge using Sinytra Connector and Forgified Fabric API (Latest Versions work perfectly)

Project FAQ Additional answers from the project team
Why aren't vehicles spawning?

Quick troubleshoot: - Check if spawn/despawn connectors are enabled - Make sure that paths are connected - Make sure that you've added at least 1 vehicle to the pool - Make sure you have installed the latest version of the mod

Will this mod be compatible with 1.19.x or older/newer game versions?

Yes, soon we will be adding support for 1.19.2, 1.19.4 fabric/forge. Support for 1.21.11 and 26.1.2 will be added when mtr supports these versions. Currently we are not planning to update to 1.21.4

Can I run it on forge?

Yes you can! Just use Sinytra Connector and Forgified Fabric API (latest versions) as a dependency and it should work just fine. We have tested if the mod is stable on forge and it is absolutely safe to use with connector.
