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.
Some time ago, a friend insisted that people should not listen to practicing architects or read what they write. According to him, the lack of logic in our discourse, the incongruity of our words, and the overzealousness in readings brought about by the biographical revision of our work were of little value.
In his book The Eyes of the Skin, Juhani Pallasmaa approaches it from the opposite direction, but ultimately gives the same advice:
The verbal statements of artists and architects should not usually be taken at their face value, as they often merely represent a conscious surface rationalization, or defense, that may well be in sharp contradiction to the deeper unconscious intentions giving the work its very life force.
