My article “Off the Grid… and Back Again? The Recent Evolution of American Street Network Planning and Design” has been published by the Journal of the American Planning Association and won the 2020 Stough-Johansson Springer Award for best paper. It identifies recent nationwide trends in American street network design, measuring how urban planners abandoned the grid and embraced sprawl over the 20th century, but since 2000 these trends have rebounded, shifting back toward historical design patterns.
This study measures the entropy (or disordered-ness) of street bearings in each street network, along with each city’s typical street segment length, average circuity, average node degree, and the network’s proportions of four-way intersections and dead-ends. It also develops a new indicator of orientation-order that quantifies how a city’s street network follows the geometric ordering logic of a single grid. These indicators, taken in concert, reveal the extent and nuance of the grid.
When a person’s forces are resolved, it makes us feel at home, because we know, by some sixth sense, that there are not other unexpected forces lurking underground. He acts according to the nature of the situations he is in, without distorting them. There are no guiding images in his behavior, no hidden forces; he is simply free. And so, we feel relaxed and peaceful in his company.
Each of us knows from experience the feeling which this quality creates in us.
And for this reason, each one of us can also recognize this quality when it occurs in buildings.
