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.
The human maker, working in unself-conscious matter, receives no worship from his creatures, since their will is no part of his material; he can only receive the response of their nature, and he is alone in fault if that response is not forthcoming. If he tortures his material, if the stone looks unhappy when he has wrought it into a pattern alien to its own nature, if his writing is an abuse of language, his music a succession of unmeaning intervals, the helpless discomfort of his material universe is a reproach to him alone; similarly, if he respects and interprets the integrity of his material, the seemliness of the ordered work proclaims his praise, and his only, without will, but in a passive beauty of right structure.
