Making Traffic Paths for maps

Hello, some maps don't have traffic built in (like some mod maps) so i wanted to make it myself, so far on the internet i havent found anything helpful about it, i only found the script ai manager that allows to record the car's path but i cant use it for regular traffic.
How can i add traffic on maps that don't have it?
thank you

It's old but still works. Basically you should make a decal road, then set Its driveability to 1

 

And check the little box first AI roads only in the decal tools at the top.

 

That's not really needed imo I make a decal road then I set the driveablity to 1. Why check that box?!
You need to check that box only when you want to select one of the AI roads

 

LoL... For some reason I was thinking about checking that box, I spent so much time fiddling with stuff its all running together in my head. I notice for me I have to reset the game after creating an AI path for them to use it right. Maybe that is just me. Not related to post, just something I see happening when I enable traffic.

 

You don't have to restart the game, you can just do ctrl+L which resets the scripts or something like that and basically applies all the AI changes made to that point

 

Thanks for that very helpful tip !
