Every time I've been hit by a car (~abt 2 dozen times, though most not in DC) has been in while in a crosswalk crossing with a signal or at uncontrolled crosswalks; always during legal crossings. I've never been hit when crossing illegally. Though there's a bit of bias in all that... when I have the right to cross, I'm a rather militant pedestrian: I only yield way at uncontrolled crossings where the motorist cannot physically react and stop in time. Otherwise, signal or no signal: I'm going. Alternately, when I am crossing against a signal, jaywalking, or at unmarked crosswalks (where I do technically have right-of-way, but I concede few know that) -- I'm far more cautious, giving way to motorists and waiting for an adequate gap.

"which affirms the recent D.C. police remarks on the crosswalk remaining the most dangerous spot for pedestrians" -- that's obvious nonsense. Yes, the largest single category is pedestrians in crosswalks. That's because most pedestrians cross the street in crosswalks. The large number doesn't imply that crosswalks are "dangerous", but merely indicates that that's where most crossing occurs, and hence the most collision incidents. Listen to the MPD, and you'll think that the best way to cross the street is NOT in a crosswalk. Bogus!!!!

"the highest number of crashes (23% on average) happen in a crosswalk with an appropriate traffic signal." Does that mean only that the light was green? or was the pedestrian crossing on a "don't walk" sign as well? I cannot count the number of times I have seen pedestrians step off the curb with a "don't walk" sign just because the light is green. Because of these fools I have ended up making technically illegal turns because the light turns red before the pedestrians clear the intersection. Yes, I am sometimes a pedestrian. No, I don't start across an intersection when the "don't walk" sign is lit.
