Your "ooh so superior" snark doesn't do much for dialog.
You do a survey to give you a look at the realities of "origination-destination by time" density lines. That helps you plan where and when you will place your highways/bus lines/rail lines [[and they may well surprise you with what they show). You try to satisfy the maximum "demand" with the "affordable resources". I wonder the last time this was done in the Detroit area. I know one was done in the fifties because I remember reading it [[and they chose the highway option).
