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.
Holzer began creating these works in 1977, when she was a student in an independent study program. She hand-typed numerous "one liners," or Truisms, which she has likened, partly in jest, to a "Jenny Holzer's Reader's Digest version of Western and Eastern thought." She typeset the sentences in alphabetical order and printed them inexpensively, using commercial printing processes. She then distributed the sheets at random and pasted them up as posters around the city. Her Truisms eventually adorned a variety of formats, including T-shirts and baseball caps.
