The lock and key combination of the highways and the automobile
unleashed an explosion in the supply of urbanizable land. While traffic
congestion has grown on exponentially on population growth, only recently have
the cumulative effects of congestion outstripped the capacity to maintain and
expand the highway network. As a result, the value of centrality is again
rising, and there is once again a need for real urbanism, and not just the faux
"New Urbanism" railway suburbanism.
