If it's really pedestrian fatalities we're concerned about, we should be implementing red right-facing arrows, which are on when the walk light is on.

Right on red, unless that arrow is on. Perhaps a blinking yellow arrow for when it isn't, just to avoid the ambiguity.

Or, when you're walking into the road, maybe make sure that drivers nearby see you. I played Ingress and Pokemon Go for years, in the city, at night, for years. Perhaps it's that I knew it put me at heightened risk so I paid more attention, but I really have a hard time understanding why people think that drivers are the only ones who need to pay attention when they're in the street.

Sure, except Americans may also have a weird obsession with driving that makes them oblivious to pedestrians, whereas many other nations may be more aware of pedestrians and thus have fewer fatalities per capita. I have no data to back up such a statement. Just anecdotal experiences.

I found the statistics in the article were not presented in a coherent manner. I couldn’t tell if right on red had a greater impact or not.
