Map version 1 created on February 9, 2011.

Map version 2 replaced version 1 on February 23, 2011, adding injury and fatality information, as well as clearer info windows. I also corrected the data: I added 2009 data twice to version 1 so the total number of crashes reported, 6,369, was incorrect. The correct number of crashes is 4,931.

I created this for Chicago to show what many seem to already feel. I also created it for my peers around the world to show how easily you can create free maps.
