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.
My point here is that in a design system every paper cut is felt. Every collapse leads to another, every new modal or unnecessary checkbox component hinders the collective refactoring that’s required to make a codebase consistent and easy to understand. When it comes to hyperobjects and design systems everything matters (although, frustratingly, it is impossible to measure success) and the smallest problem is just a signal in the dark—a premonition of a monster; organizational dysfunction writ large.
