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.
Along with being a meeting place, the stoop is a space of spectatorship. A street lined with stoops is a kind of lateral stadium, ideal for viewing the passing parade, whether formal ones like the giant Gay Pride and Halloween Parades (until their route was changed a few years ago) or the more informal quotidian version. Hanging out on the stoop allows the sitter to observe the dance (Jane Jacobs’s ballet) of daily activity, to notice what is out of the ordinary, to provide the kind of public presence that prompts neighborly behavior.
