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.
[Andy Crouch] quotes the Japanese theologian Kosuke Koyama saying that “the speed of God” is three miles an hour because that was the speed at which Jesus moved through his world. So maybe, and I think this is one of the chief burdens of Andy’s book, what makes the most sense for us is to try whenever possible to move at the speed of God – and in that way refuse the offer of superpowers.
Of course, this dovetails with a lot of things people have been writing lately about slowness, but what I like about Andy’s book is that it specifies why we can find ourselves responding so warmly to the possibility of slowness. What happens when we seek superpowers, and especially super-speed, is the sacrifice of what I want to call our proper powers – the powers through the exercise of which we (heart-soul-mind-strength) flourish in love.
