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.

I have found the solution

I don't know if someone have figured out this one, but here's how you turn it on.

Basically what you have to do. Is you have to go to Content Manager on the Main Menu, and go to Mods. The Toggle Traffic Lights, you just have to turn it on.

I hope this helps ;)

So you want to remove the visuals but keep the functionally of traffic lights? I don't think that's possible -- the lights are automatically placed by C:S when the variable for traffic lights is set.

Yes, the intersection shows and there is a place for traffic lights and they are installed and fix the visual problem (but those that work hinder me). Road id=1529901012.

Hm, that seems like heavily modded roads. I only ever used it with "normal" road mods without any crazy changes. The road from your screenshot seems pretty changed and glitchy. Don't really know what is and isn't possible to mod on roads.

If there's no place set for traffic lights TTL might not be able to set it. Or TTL doesn't recognized that intersection as road intersection because it's so heavily modded.
Maybe Lights gets changed but there's no visible indication via lights appearing. Try the highlighting from TTL -- does that show an intersection and light?
Which mod contains that road?

Craxy, there is a road with such a problem:
The author said: "forgot to set the traffic light on".
I thought it was possible to do both in No automatic trafficlights "Off":
TM:PE, in my opinion, does not put the "disabled" traffic lights, and working interfere with me.

What do you mean with "deactivate (not delete)"? Change an (existing light) from red to green? I think that's possible with Traffic Manager. Or do you mean disable the functionality but keep the traffic lights visually? I don't think that's possible; but you might be able to simulate this with Building Anarchy or something similar by manually placing the traffic lights assets.

Thanks for the mod!
Can you add a function to deactivate (not delete) an installed traffic light?
