In Stockholm Keolis has started to install S-1 Gard Dangerzone Deflectors on their buses.
It is an american invention that prevents people that fall under buses to get run over. Instead they are being pushed outwards (deflected).

On the companys home page there is a movie with a stuntman continously throwing himself under a bus in different way to show how it works.
