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.
Christopher Johnson says “prescriptivists” or “Cute Curmudgeons” — people who are interested in only policing usage and grammar rules — are “linguistic poison sniffers.” They turn language into “a source of potential embarrassment rather than pleasure.”
Johnson sees his job as getting people to love and appreciate language by being curious about and paying attention to “what makes language delicious.”
This reminded of Olivia Laing’s distinction between identifying poison and finding nourishment.
Everywhere you look these days, there are lots of poison sniffers, but very few cooking a delicious meal…
