From 1870's ubranisation peaked in 1920s, post World War 2 creation and movement to suburbia.
1st reset urbanization
2nd reset Metropolitan-ism with the city and it's expansion into suburbia
could the 3rd rest be the creation of more mega regions, a grouping of metropolotin areas like the Boston, New York and Washington DC area.

He is for increasing speed of travel. Making connections to hub cities.
In the 40s people could travel to and from Chicago for day shopping from 100s of miles away, so I am not sure this prediction will pan out. We already had that in many parts of America and it only stayed that way in the dense east coast corridor.
The Bay area and chcicago have limited train commutting cultures.
Telecommuting and decentralization seem more likely to me. And that will reduce congestion on the current roads.
Special exceptions due to tourism may make LA, Las Vegas, and Orlando move to a model where most of the workers would commute in trains.
