DRIVER VISIBILITY QUALITY: COMPARISON OF VISIBILITY QUALITY METER DATA WITH HUMAN VISUAL PERFORMANCE

The objective of this investigation was to calibrate the performance of a Visibility Quality Meter (VQM) against a measure of human contrast perception. The VQM quantifies a meaningful aspect of driver visibility quality, modulation transfer. Data were collected from 28 volunteers who represented younger and older United States driving populations. Various simulations of driving-related optical degradation (fogged and iced windshields) were interposed between a subject or the VQM and a visual target. The calibration took the form of qualitative and quantitative comparisons of VQM to human modulation across a wide range of spatial frequencies for the different degradation conditions.
