I'll admit that I didn't give the Yahoo Traffic RSS feed data that close of a look the first time around (I had just assumed that it was purely 'boring' textual data), but now that Greg has posted a link to his Google-Yahoo Traffic Maps mashup, I see that each of the traffic incidents include lat/long - making them easily placable on any map. This is too rich! Now, if only a method of getting driving directions and then attempting to figure out if any of the incidents will affect your travel. (hint! hint!)
