Hi, I like your mods.
I have a few suggestions:

• make the road signs one-sided - it will look more realistic than now
  

• possibility to place one-sided delivered tokens with their backs facing each other on one field

• possibility to place traffic signs on each outermost striped square, not on the road
  

• add the following traffic signs:
  

  Well, that would be enough. I have to be modest :)

  Thank you for the good work and I'll be surprised by what you make of this.

Im currently working on an other project, but will add them as soon as possible, nice suggestion! Maybe split the toolbar a bit
to not overload them too much.

One sided signs is possible, a lot of work but can be done.

If you mean, one field, one tile? This is not possible, the game doesn't allow to "overlap" tiles.

The only way to put for example a sign on the road, is via displacement.Let me investigate if y can introduce kinda placement control.

New signs are allready on the way, all those suggested ones.

Will add new toolbars to have better control (37 signs in total).

If you can't place two objects on one square, that's okay. One-sided traffic signs solve this problem.
I recommend contacting DeznekCZ, they have a quite interesting solution for placing street lighting.
