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.
Markkula wrote his principles in a one-page paper titled "The Apple Marketing Philosophy" that stressed three points.
The first was empathy, an intimate connection with the feelings of the customer: "We will truly understand their needs better than any other company."
The second was focus: "In order to do a good job of those things that we decide to do, we must eliminate all of the unimportant opportunities."
The third and equally important principle, awkwardly named, was impute. It emphasized that people form an opinion about a company or product based on the signals that it conveys. "People DO just a book by its cover," he wrote. "We may have the best product, the highest quality, the most useful software etc.; if we present them in a slipshod manner, they will be perceived as slipshod; if we present them in a creative, professional manner, we will impute the desired qualities."
