Are there any examples of sim games like this being used by real cities? I could imagine it'd be a useful visualization for where tax revenues are generated/utilized at the very least.
I remember a software, where you could take real world streets, run traffic simulations on it, and also make changes to the street layout. Basically, fix the crossing that costs time on your commute every day.
I read about it many years ago, sadly forgot its name and a bit of searching didn't make it show up. So leaving this here in hope someone knows what I am talking about and drops a link. I'd like to read up on what happened to the project as well.
A/B Street seems like a good candidate.
