A TRACK WORKER SAFETY SYSTEM

摘要

A safety system for providing early warning notifications to an authorized
track worker
performing official duties along a rail road network is disclosed herein. The
safety system
determines the position of the authorized worker and determines an estimated
time to
collision between the authorized track worker and an approaching rail vehicle.
The result of
the safety system is that the track worker has enough time and sufficiently
accurate warning
that will enable the track worker to move to a point of safety so as to remain
unharmed by the
approaching rail vehicle.
