From Streetsblog DC (http://dc.streetsblog.org/2011/11/23/mapping-the-consequences-of-our-automobile-addiction/),
Over 30,000 die on US streets and highways every year. ITO, a British research firm, created a US map of all road deaths from 2001-09.

Looking over the information, it is staggering to put road deaths in a geo-spacial format. While "cool" may not be the most appropriate word to use here, it is amazing in ways. I had no idea, but am honestly not surprised, that the worst pedestrian hot-spot in Fort Collins is College Ave north of Drake.
West of the Mississippi, the map can be used to construct a rudimentary road map of the Western United States. Notice that the Interstates appear thicker than US or State highways. Anyone else notice interesting patterns?
Man, after seeing that map I'm staying on this side of the Mississippi! The east is a death zone!
It would be interesting to see that data weighted against population density- I'll work on that right now (damn, it doesn't look like the data was geocoded by FHWA, so those bastards would have to do it)
Weighted against pop density would be a heck of a lot more meaningful- right now it looks like pretty much every national map that has to do with counting transportation related things- the east is a big blob and the west follows the interstates
More than anything, you're looking at a chart of VMT...
