Abstract
Pedestrian-Vehicle safety systems for loading docks are disclosed herein. An example method disclosed herein includes sensing whether a person is within a certain area adjacent a dock face of a loading dock, emitting a first signal in response to sensing the person being present within the certain area, sensing rearward movement of a vehicle toward the dock face, emitting a second signal in response to sensing rearward movement of the vehicle while the person is not present in the certain area, and emitting a third signal in response to sensing both the rearward movement of the vehicle and the person being present within the certain area.
