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.
Only a mind opened to the quality of things, with a habit of discrimination, sensitized by experience and responsive to new forms and ideas, will be prepared for the enjoyment of this art. The experience of the work of art, like the creation of the work of art itself, is a process ultimately opposed to communication as it is understood now. What has appeared as noise in the first encounter becomes in the end message or necessity, though never message in a perfectly reproducible sense. You cannot translate it into words or make a copy of it which will be quite the same thing.
