MODELING VISION WITH HEADLIGHTS IN A SYSTEMS CONTEXT

The Headlamp Evaluation Model accepts as input the candlepower patterns of the headlamp system being evaluated and provides a measures of driver visual performance based on a large number of simulated seeing distance tests and glare discomfort checks on a standardized test route. The output of the Model, termed the Figure of Merit, is the percentage of the distance traveled by the simulated driver on the standardized test route in which the seeing distance to pedestrians and pavement lines, and the discomfort glare levels experienced by opposing drivers, simultaneously meet certain acceptance criteria. /SASI/
