How To Use:
- Install Fabric API, Minecraft Transit Railway, and MTR Traffic Addon.
- Open your world and take the Traffic Spawn Connector, Traffic Despawn Connector, and Traffic Dashboard from the MTR Traffic Addon creative tab.
- Place spawn connectors where traffic should appear, and despawn connectors where traffic should leave.
- Open the Traffic Dashboard to view connectors, refresh routes, clear active vehicles, and manage vehicle pools.
- Select which vehicle models each spawn connector can use.
- For intersections, create an intersection area in the dashboard and assign signal groups for incoming roads.
