I'm trying to work up a plan for traffic in my city, and I think it's easy enough for me to figure out how many cars can make it through a stopsign unopposed in an hour, and how many cars can make it through a stoplight opposed in an hour... but it's all for naught as I don't know how many workers are in a car.
I know that low wealth, high density residential buildings have 400 workers, 200 shoppers and 100 students. What I don't know: how many cars does that turn into?
