About this project
What does Realistic Traffic Control add?
Realistic Traffic Control
Realistic Traffic Control is a complete reimagining of the original Traffic Control mod by CSX8600, developed and maintained by Gamearoo.
Built for both Minecraft 1.12.2 Forge and Minecraft 1.21.1 NeoForge, RTC introduces a more immersive and realistic system of traffic lights, railroad equipment, sensors, pedestrian signals, signs, message boards, and controllers—perfect for cities, roleplay, railroads, and transportation infrastructure.
This is not just an update—it’s a total overhaul.
Features
- Redesigned from the ground up with new models and mechanics
- Manual and automatic traffic light control systems
- Functional sensors, timers, and pedestrian crossing logic
- Railroad crossing equipment and train detection
- Digital Signs and programmable Message Boards
- Customizable through in-game GUIs and supported scripting integrations
- Support for realistic behaviors such as flashing signals, directional timers, and automated signal operation
- Integration with supported computer mods for advanced automation
- Minecraft 1.21.1 integration with Create, including detection of Create trains
Supported Versions
- Minecraft 1.12.2 — Forge
- Minecraft 1.21.1 — NeoForge
Minecraft 1.21.1 is currently considered Alpha.
The major RTC features and content are already available. The Alpha status mainly reflects continued testing, bug fixing, and polishing of the 1.21.1 port.
The current target for the full Minecraft 1.21.1 release is early 2027. When 1.21.1 leaves Alpha, RTC will move to Version 5.0.0.
This timeframe is a target and may change depending on testing and development.
Development
RTC is actively maintained, with additional fixes, improvements, integrations, and features continuing to be developed.
The goal is to provide a flexible traffic and transportation system that works for everything from simple intersections to large-scale city and railroad projects.
Credits
Realistic Traffic Control is based on the original concept and work of CSX8600.
Full credit for the original Traffic Control mod goes to them.
