A Designer's Toolbox

I'm prepping the monthly Twitter round-up for tomorrow, and this one tweet is too hard to include because it's a list with four photos.

I've mentioned Melissa and Chris Bruntlett a few times before (here's one), and I've admired their book Curbing Traffic. This is a tweet they posted late in May:

A designer’s toolbox for living streets:

🚗 Modal filters
🌸 Facade gardens
🪑 Ample seating
🐢 Speed tables
⤴️ Chicanes/bulbouts
🧱 Textured paving
👁️ Raised intersections
🌳 Shade trees
🚲 Bike parking
🪴 Planter boxes
💡 Human-scale lighting
👞 Low/no curbs
🛑 Limited signage

And then they included these four photos to illustrate the list:

Those are some nice human-scale spaces. 

What would this country be like if we could make new places like that here? What would have changed, from the policy level to the social level, to make them possible?
