Abstract: A system for enhancing safe operation of industrial vehicles includes at least one of three sets of sensors for detecting pedestrians in zones and providing appropriate responses. Zone 1 includes a two to four foot region around a stationary vehicle which might include personnel who had recently been conversing with the vehicle's operator. Zone 2 extends from 2 to 6 feet from the vehicle and personnel entering Zone 2 will cause the vehicle's horn to sound to prevent their walking into the side of the vehicle. Zone 3 comprises hidden danger zones where personnel may enter a region where an industrial vehicle from outside the area and be unaware of the vehicle's presence. Motion detectors associated with Zone 3 cause activation of an RF tag that reflects a radio signal transmitted by the vehicle. The sounding of the horn will notify both the pedestrian and the vehicle's operator of the potential danger.
