Toggle Traffic Lights

Tool to remove or add traffic lights at junctions. With Cities:Skylines patch 1.7.0 (Mass Transit)[] that functionality was directly included into the game. But Toggle Traffic Lights provides functions beyond of C:S:
  • Access the Junction Tool directly from the Roads Menu.
  • Activate and Deactivate the Junction Tool everywhere. Disabling the Intersection Tool restores the previous used tool.
  • Remove (or add or reset) all traffic lights at once.

A more detailed description can be found on GitHub:

Enable Junction tool via:
  • Button in roads menu.
  • Ctrl+T. Opens Roads Menu.
  • Ctrl+Shiftt++T. Keeps current location. Remembers current tool and restores it when you press the shortcut again.
  • Ctrl+Alt+T. Opens Traffic Routes Junctions Info View. Remembers current tool.
Use the Elevation keys (PageUp and PageDown) to change the view: Overground, Overground with tunnels visible, Underground (Info View, everything's painted in white). Doesn't work with the built-in C:S Traffic Routes Junction tool (Ctrl+Alt+T). This uses the default C:S tool without changes.

Batch commands:
Located in the (C:S built-in) Traffic Routes Junctions Info Window. Besides opening that window via the Info View Menu on the top left you can use the shortcut Ctrl+Alt+T (see above) or right click on the TTL button in the roads menu.

Disable Traffic Lights:
When the checkbox is checked new junctions are always created without traffic lights.
Existing Traffic Lights aren't touched by this option. Neither does it prevent manual toggling of traffic lights. All it does is ensure all newly created junctions don't have traffic lights.
The Setting is located in the Traffic Routes Junctions Info Tab.

Note:This is set on a per savegame basis and is not a global setting! That means you can play one map with this option enabled (-> no traffic lights for new junctions), while on another map you use the default C:S behavior.

Note: Previous saved traffic lights via TTL (prior to Mass Transit patch) are discarded. The new version uses the C:S built-in way to save Traffic Lights.

This mod is the best :steamhappy:
as the city grew the traffic coming in started backing up on the freeway - not ideal! so I built a roundabout and exits from the city before and after the roundabout.
The roundabout solved the mess going into the city, but I noticed the exits were chaotic - no CIM was giving way! so I put traffic lights on one of the freeway junctions and now everythings calm & peaceful again

@hannebambel002: I can't reproduce that behavior. I uploaded a new version with some logging: Can you load a map and remove all signs, close game and search in your output_log.txt file (in "Steam\steamapps\common\Cities_Skylines\Cities_Data\") for lines that contain message regarding TTL (marked with "[ToggleTrafficLights]") or any exceptions? thanks.

@Craxy: thank you for the update, but it dont work as it should. if you set stop signs and want remove with your new function tab the stop sign in street (not on display) will still stay and all cars stop for a moment. if you delete the sign individually it works

@hannebambel002: The difference between stop signs and traffic lights are: By default there are no stop signs at any junction. Therefore a stop sign is always deliberately placed by the player.
Ergo: Thought noone would need that.

But here you are. And luckily that was easy to implement -> new version with option to remove all stop signs is uploaded.
Open the Traffic Routes windows, go into the Junctions tab (where you can remove all traffic lights; ) and left-click on the grey-out stop sign icon while holding Ctrl (there's a tooltip when you hover the mouse over the icon).

I didn't placed a special button (like for changing all traffic lights) -- I don't think that's often used feature. So i think it's ok to keep it kinda hidden ;)

very good mod to prevent new traffic lights:steamhappy:
is it possible to add a function to remove all stop signs with one click? with traffic lights it works fine, but i am missinng this for stop signs

@Paper rancher: Just tested TTL and it seems to work alright -- but I don't own the Green Cities dlc.

Have you other mods enabled? Try disabling all of them and just reenable TTL (don't forget to restart C:S after disable the mods -- some hooks might stay in the modded code during runtime).
If TTL still doesn't work: can you upload your output_logs.txt? Errors should be logged in there.

Why is it the button for this doesn't show up in my game?
