No matter what you do there is always going to be someone to walk/ride in a street and get hit by a car. Not pay attention and walk on tracks. Fall off an elevated platform of tracks, ect.

The best thing you can do is have signs and notices making people aware of what is going on around them.

And no, I don't need to watch the video. I got rookied as a kid to watch faces of death. Seen enough of that to last a lifetime. But ill take your word on it
