Abstract
The objective of this project was to improve a driver's field of view for large trucks used in the mining industry. Rearward viewing was enhanced by improving the rearview mirror designs. Rear vision was accomplished using a closed-circuit television system. Views ahead, to the right, and downward were obtained with a blind area viewer (bav). The bav is a unique combination of fresnel lenses housed in a shielded, environmentally protected enclosure that produces an image of the area in front of and downward 70 degrees and to either side of the bav 30 degrees. The improved visibility devices were evaluated by long-term, in-mine testing. The right side mirror (rsm) and bav provide the greatest improvements for the least cost and are commercially available. Application of the rsm and bav should achieve a reduction in accident potential and greater vehicle productivity by enlarging and improving the equipment operator's visibility and making previously blind areas and hazardous situations detectable.
