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 big misconception I’ve seen designers and developers often fall victim to is believing that handoff goes one way. Designers hand off comps to developers and think their work is done. That puts a lot of pressure on the designer to get everything perfect in one pass.
Instead, great collaboration follows what Brad Frost and I call “The Hot Potato Process,” where ideas are passed quickly back and forth from designer to developer and back to designer then back to developer for the entirety of a product creation cycle.
