Speed detection system HIS
HIS is used by level crossing protection systems along high-speed lines.
By gauging the speed of approaching trains, the level crossing protection system is activated at different distances ahead of the crossing. The barriers are lowered early for fast trains, while for slower ones, like freight trains, there is a shorter striking-in distance. In this way, the lowering of the barriers is adjusted for the smoothest possible interaction between rail and road traffic.
