Google map based tool that uses census data to graph commutes. One large flaw is that it assumes everyone drives, but overall it’s awesome. Oh, and for some reason they chose not to support Internet Explorer (?!).
Play with this a while and all kinds of interesting trends pop out. Compare “from” data in any Seattle zip code (try 98001) with a suburban zip code (try Bothell 98011), and you’ll see a short commute with fat lines compared to a very wide range of commutes with spindly spider web lines throughout the region.

This is delightful. It’s nice for confirming what intuition suggests: central, dense zipcodes are responsible for less traffic (as source *and* destination). 98052, on the other hand…
Perhaps our regional efforts to be “fair” in funding transportation infrastructure should take this into account.
