How many pedestrian are hit by cars & trucks while staring at their cellphones and not watching traffic?

I have seen several close calls where pedestrians are about to step off a curb, then suddenly they look up from their phone and see a bus barreling at them. There must be statistics on this. Post links with your answer if possible.

Also, I’m sure there are cases where a driver on a cellphone encounters a walker on a cellphone and their combined lack of attention causes Murphy’s Law to kick in.
