Traffic Manager: President Edition

Traffic Manager: President Edition
helps you manage your city's traffic. This mod allows you to
  • toggle traffic lights at junctions,
  • add yield and stop signs to junctions,
  • define timed traffic lights that can adapt their behavior depending on live traffic measurements,
  • modify speed limits,
  • define vehicle restrictions (e.g. disallow vehicles on certain roads),
  • define junction restrictions (e.g. disallow pedestrians to cross the street),
  • define parking restrictions (e.g. prohibit cars from parking road-side),
  • change lane arrows and connect individual lanes with each other,
  • clear traffic and
  • toggle despawn on/off
It additionally includes
  • its own Advanced Vehicle AI that modifies the way your cims choose their lanes,
  • modified lane splitting/merging rules on highways (read the manual!),
  • a Parking AI which disallows "pocket cars" and improves the simulation regarding parking space usage, and
  • Dynamic Lane Selection (DLS), a lane selection algorithm that allows cims to switch to alternative lanes while en-route

This mod is based on the original Traffic Manager Mod by cbethax and Traffic Manager Plus by seiggy. If you have subscribed to another Traffic Manager mod, please first deactivate it in your Content Manager (in-game) before trying this one out.

After the newest update i can no longer use this mod. i am subscribed to it, and i can see the settings ingame, but the button you click on is missing. I play on an ultrawide monitor, 2560x1080

Yes, including mod settings files that are divided between the main game folder and the secondary folder located in AppData/Local on your system drive. I advise backing up the more complicated ones like AVO, Rush Hour, IPT2, WGRealisticPop and others that contain a lot of precise settings, and would likely take hours to recreate.

If your internet connection is good enough you can back up the settings files I mentioned and delete the entire game, along with the CO folder in AppData. Then re-download everything and swap the settings files for your personal ones.

Of course this will have no effect if your problem comes from incompatibility or an outdated mod, which you would've simply reinstalled again this way. You should check for that first.

@Artemis--I don't understand what you mean by "clean up your game files"? Is that deleting the mods folder and letting them all re-download? Thanks!

That shouldn't occur in the first place. Instead of asking someone to put a bandade on the problem, find the cause for it.
- Review your mods for incompatiblities and whether they are updated and confirmed to work with the newest version of the game (read the description, don't count comments - if it works for a number of different people, it does work)
- Make sure something that you did isn't the cause for your problem
- Finally, clean up your game files. In most cases that's all you need to do. It's also a good practice to do this once every few months. Keeps everything running smoothly (mods I mean).

Can you add a remove button for pedestrians, too? I have , especially tourists, who, through some glitch, I'm guessing, just stand in the middle of the road and slow down traffic. They never move.

Update: after a fresh install everything is working again, Thanks @Artemis!

Better "busses" than "bus's" -- myself (a Hailey)
HayleyFan219 Jan 15 @ 3:23am 
No offence, but the word "buses" is spelled incorrectly. It clearly does not have two s's in it.

@artemis To be honest i did not read it all. I did some reading only when i had problems.This time i could find any answer cause the problem is so random. I did not know about the leftovers. I will try a clean install and then add mods one by one and see how it goes. I will come back with an update but it will take some time ( german internet is the best .. *not* ) Thanks for taking your time and replying man! :*

And when you're trying to show a path of a car, do all of the following:
- one with the traffic tool showing the way (as long one as possible, but in a way that makes junction details still visible)
- the exact same view, but with the lane connector feature activated so that the layout is visible
- the exact same view, but with vehicle restriction feature activated (if you have districts with traffic policies active, make a screenshot for those as well)

It might seem like a waste of time, but some combinations may result in very curious outcomes, and one bad junction can lock down a 100k city in traffic... :)
