MTR Traffic Addon
by opaleq
MTR Traffic Addon, for Minecraft Transit Railway worlds, generates road traffic with spawn points, traffic lights and intersections.
What it does
Traffic spawn and despawn connectors are placed on a road network and set where vehicles appear and leave. Routes are managed from an in-game Traffic Dashboard, and each spawn point can draw from its own selected vehicle pool. Intersection areas run signal phases, and vehicles keep their spacing and queue behind one another, while keeping track of MTR vehicles on the same roads.
The addon is built on Minecraft Transit Railway, so it needs that mod, along with Fabric API, Forgified Fabric API and Sinytra Connector. It runs on the client and the server, so both sides need it. The vehicle models include eight sedan models in eight color variants, plus hatchback and Nissan Sentra models, and a sample bus network built with MTR shows how the pieces fit together. Files cover 1.20.1, 1.20.4 and 1.21.1 for Fabric and Forge, and the code is released under a custom license.
Key features
Traffic spawn connectors
Connectors mark where vehicles enter and leave the road network, and they can be placed along MTR-based routes.
In-game traffic dashboard
A dashboard screen manages routes and traffic settings without editing files by hand.
Vehicle pools per spawn
Each spawn point selects which vehicle models it draws from, so areas can have different traffic.
Intersections with signal phases

How it compares
MTR Collisions is a Forge-only mod for 1.20.1, server-side only, and is all rights reserved, so it does not add traffic to the roads. Create: Railway Evolution runs on Forge and NeoForge for 1.18.2 – 1.21.1, with the server required and the client optional, under a Creative Commons Attribution Non Commercial license. Public Transport Mod covers Fabric, Forge and NeoForge for 1.20.1 – 1.21.1, is client and server, and uses the MIT License.
