Design, it seems, is not only becoming more methodical but also more scientific. This is not surprising. Design as a discipline has moved from “product beautification” to being a central part of product development. It has incorporated methodologies from human-computer interaction, sociology, and anthropology as well as advertising and management. And with the rise of design thinking, a wider range of professional disciplines are using creative methods.
I don’t want to criticize design methodologies. But against the backdrop of an overly structured design process, it is important to remind our community that there is one fundamental aspect to design that cannot be formalized in a methodology. And that is intuition.
Walk Appeal promises to be a major new tool for understanding and building walkable places, and it explains several things that were heretofore either contradictory or mysterious. It begins with the assertion that the quarter-mile radius (or 5-minute walk,) which has been held up for a century as the distance Americans will walk before driving, is actually a myth.
Both images below are at the same scale, and the yellow dashed line is a quarter-mile radius. On the left is a power center. As we all know, if you're at Best Buy and need to pick something up at Old Navy, there's no way you're walking from one store to another. Instead, you get in your car and drive as close as possible to the Old Navy front door. You'll even wait for a parking space to open up instead of driving to an open space just a few spaces away… not because you're lazy, but because it's such a terrible walking experience.
The image on the right is Rome. The circles are centered on the Piazza del Popolo (North is to the left) and the Green radius goes through the Vittorio Emanuele on the right. People regularly walk that far and then keep on walking without ever thinking of driving.
