The Place Diagram

PPS Project for Public Space, 2003

Imagine that the center circle on the diagram is a specific place that you know: a street corner, a playground, a plaza outside a building. You can evaluate that place according to four criteria in the red ring. In the ring outside these main criteria are a number of intuitive or qualitative aspects by which to judge a place; the next outer ring shows the quantitative aspects that can be measured by statistics or research.

Note 1: There is a more recent diagram, with contemporary colors, in the article linked above, but this one from 2003 is for me more legible.

Note 2: We can learn a lot from urban planning for designing Web communities.
