ABSTRACT
The high beam provides a wide swath of light, about parallel with the road, with greater intensities than the low beam. The high beam is designed to be used when there is no oncoming traffic or traffic being followed, which limit its utility. It has been found that in most night driving situations drivers stay on the low beam, even when conditions permit use of the high beam. The principal human factors analysis in the case is concerned with determining if the driver of the truck had an adequate opportunity to become aware of the pedestrian in the road in sufficient time to avoid him. The Human Factors and Ergonomic expert was asked to consider the contributions to the unsafe event made by the behavior of the pedestrian. The basic or traditional Hazard Control Hierarchy is a relatively simple method of system safety analysis that can be applied to the design and operation of the fuel gauge in the car.
