Abstract: Systems and devices that will notify train system maintenance workers of an approaching vehicle and, conversely, will notify the operators and administrators of train systems of train system maintenance workers within the vicinity of an approaching section of track. Embodiments of the safety systems and methods disclosed herein may use track and direction information and/or LiDAR to assist in determining vehicle positioning and/or speed particularly where there are two or more possible tracks or vehicle paths in close proximity to each other.

Abstract: Systems and devices that will notify train system maintenance workers of an approaching vehicle and, conversely, will notify the operators and administrators of train systems of train system maintenance workers within the vicinity of an approaching section of track. Embodiments of the safety systems and methods disclosed herein may use proportional warnings based on the speed or proximity of approaching vehicles as well as the specific location of such approaching vehicles relative to worker positions to help avoid worker warning fatigue.
