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.
Join me. Grab whatever you’ve got. Open the bag. Pinch it on its crinkly edges and pull apart the seams. Now we’re in business: We have broken the seal. The inside of the bag is silver and shining, a marvel of engineering — strong and flexible and reflective, like an astronaut suit. Lean in, inhale that unmistakable bouquet: toasted corn, dopamine, America, grief! We are the first humans to see these chips since they left the factory who knows when. They have been waiting for us, embalmed in preservatives, like a pharaoh in his dark tomb.
