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.
The demand for “originality”—with the implication that the reminiscence of other writers is a sin against originality and a defect in the work—is a recent one and would have seemed quite ludicrous to poets of the Augustan Age, or of Shakespeare’s time. The traditional view is that each new work should be a fresh focus of power through which former streams of beauty, emotion, and reflection are directed. This view is adopted, and perhaps carried to excess, by writers like T. S. Eliot, some of whose poems are a close web of quotations and adaptations, chosen for their associative value, or like James Joyce, who makes great use of the associative value of sounds and syllables.
