Adele Peters reports on a "new visualization shows the footprint of each [parking] lot, arranged in a puzzle-like design next to every other parking lot in greater Los Angeles, to make a point about how cities use space."

"The visualization is part of a project called What the Street? that inventories parking lots in 23 cities around the world, along with the space used for roads, rail lines and rail yards, and bike paths and bike parking," adds Peters. "The code for the project is open source so it can be applied to other cities."

Peters also notes that a shift to "on-demand autonomous cars" could eventually open up some of this space for other uses.
