Letchworth is a Garden City. Brasilia is a "towers in a park" type Modernist city. You're interested in "towers in a park."

Historically, cities like Brasilia were designed around the logic of the car. For example, most roadway intersections feature over and underpasses, cars are completely segregated from pedestrians. By most accounts, it doesn't work so well.

There's got to be a better term for it.

But yeah, this kind of design doesn't seem to work well no matter the density of the buildings. Cities really need to work around pedestrians.
