Pedestrian Safety in America?

Kaid Benfield argues in the Atlantic that one of the most dangerous things you can do in the United States is to walk:

The nonprofit advocacy coalition Transportation for America (NRDC is a member) has found that, from 2000 through 2009, more than 47,700 pedestrians were killed in the United States. This is the equivalent of a jumbo jet full of passengers crashing roughly every month. On top of that, more than 688,000 pedestrians were injured over the decade, a number equivalent to a pedestrian being struck by a car or truck every 7 minutes.
