I"m not sure I agree with the setup. He's weighting clutter types based on his personal experience, eg a newsstand (=3) is weighted 20 times higher than a tree (=0.15). It's very subjective, and like the model implies a desolate empty parking lot with no trees is somehow ideal. Important factors like urban vitality, utility, or aesthetic quality are not quantified so easily.

If you want to see well-designed cities, look at Europe. Helsinki has both deep integration with nature, and high-quality public services. Denmark does very well with cycling, which improves public health and noise and air quality. Etc. I like to focus on countries that rank highly on the World Happiness Report, and try figure out what they're doing right.
