Marchetti posits that although forms of urban planning and transport may change, and although some live in villages and others in cities, people gradually adjust their lives to their conditions (including location of their homes relative to their workplace) such that the average travel time stays approximately constant.

Yeah, that's a strange conclusion.

You are right. I just copied the title of the cross post. Will remove it.

It follows that if a proposed housing solution is over an hour from the jobs, it wouldn’t work well. But still a weird conclusion because I can’t recall anywhere that proposed building housing over an hour away from the jobs as a serious housing solution.
