Traffic control + Roads(City) & Signs mod by Teerth
If you have ever tried to build a believable city in Minecraft, you know the struggle: the buildings look great, but the streets feel empty. No working traffic lights, no road markings, no signs telling your citizens where to go. That is exactly the gap that the Traffic control + Roads(City) & Signs mod by Teerth fills. Created by a solo developer named Teerth, this add-on brings functional traffic signals, an enormous library of signs, and a solid dose of police equipment to your world, turning flat streets into living, breathing urban environments.
What This Mod Actually Adds
At its core, this is a city-building utility mod. Instead of decorative blocks that just sit there, you get traffic lights that genuinely cycle through red, yellow, and green. That single feature changes everything about how a city feels, because intersections suddenly have rhythm and purpose.
- Working traffic signals with real light cycles
- Over 100 circular and standard road signs, with more planned
- Road blocks and city street components for building proper intersections
- Police-themed props and equipment for law enforcement builds
- Crafting recipes for the majority of items
The sign collection is the standout for detail-oriented builders. Speed limits, warnings, directions, and regulatory signs let you dress a highway or downtown district exactly the way you want. Teerth has also stated that custom sign requests are still being accepted, so community suggestions can end up in future updates.
Minecraft Versions and Loader Support
Which Versions Work
The mod is built for Minecraft Forge and currently supports Minecraft 1.16.5, 1.18.2, and 1.20.1. Forge 1.16.5 or newer is required, so make sure your loader matches the game version you are running. One important note from the developer: the 1.20.1 build may not play nicely with Optifine. If you run into rendering trouble there, switch to Embeddium or another shader-compatible performance mod instead.
Server and Modpack Friendly
Multiplayer fans are covered too. The mod has been added to Aternos, which means you can run it on a free hosted server without jumping through hoops. Just confirm that every client has the correct mod version installed. Modpack creators are welcome to include it as long as credit is given to Teerth.
Pairing It With Other Mods
This is where the add-on really shines. It is designed to sit alongside vehicle and transit mods, so you can combine it with Immersive Railroading, MrCrayfish's vehicle mod, and similar projects. The result is a city where trains roll into stations, cars queue at red lights, and pedestrians follow signage. If your goal is realism, this combination delivers it far better than any single mod could on its own.
Players who prefer a frictionless setup often turn to the foxygame.net launcher, whose add-on catalog handles version matching automatically, so the Traffic control + Roads(City) & Signs mod by Teerth lands in the right profile without manual file juggling. It is a small convenience that saves a surprising amount of troubleshooting time.
How to Install
Getting started is straightforward, but back up your world first, especially before updating between mod versions.
- Install Minecraft Forge 1.16.5 or newer for your chosen game version
- Place the mod file into your mods folder
- Launch the game with the Forge profile
- Load a test world and confirm the traffic lights cycle correctly
If you want to know how to install on a server, the process is nearly identical, but the file goes into the server's mods directory and every player needs the same version. The developer has also published video guides covering both standard installation and Aternos setup.
Things to Keep in Mind
Teerth is upfront that the mod may contain undiscovered bugs, and reports are handled through the project's Discord and issue tracker rather than a formal support desk. Backporting to 1.15.2 or older is not planned, so players on legacy versions are out of luck. Editing or reusing the mod's models and code requires explicit permission, though recording videos and building modpacks are both fine with proper credit.
Final Thoughts
For anyone serious about urban Minecraft builds, the Traffic control + Roads(City) & Signs mod by Teerth is one of the most practical additions available. Working signals, a massive sign library, and police props cover the details that most city mods ignore entirely. If you want to download Traffic control + Roads(City) & Signs mod by Teerth, grab the build that matches your Forge version, test it in a backup world, and start laying out intersections that finally feel like a real city.
