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.
When we use non-spatial social apps, we often understand that another's cognitive presence is there, but we can't feel the more human presence we're wired to need. When we're not social distancing, we fulfill this need elsewhere, outside of software. We meet for coffee. We go on a walk. We play a game, or show a friend something funny on our phone and watch them laugh. We have infinite options at our disposal for relating to others. Though the lack of these same options inside the software we use is sometimes inconvenient, we can usually get over it.
But things are different right now. We're constrained to rely almost exclusively on software for social interaction. What are usually minor inconveniences in our existing applications are now the main factor preventing us from fulfilling our social needs.
