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.
Consider, for example, how “broken world thinking” can benefit product design. What if the person (or team) who invented a new technology collaborated with the person (or team) who would one day repair the same technology? What if the innovation stakeholders and the infrastructure stakeholders collaborated closely with the end users? What if every new product designed by a technology company was designed in such as way as to factor in what happens to the product after planned obsolescence?
