Experiments on Driver's Visibility During Night Driving and Polarized Headlighting System

The paper contains experimental results related to the driver's visibility and polarized headlighting system. The interpretation of visibility is done in terms of contrast in almost every situation. Results showing the variation of high and low beam intensity as a function of lateral displacement between the vehicles are presented. Parameters like headlamp mounting height and height of driver's eye point (DEP) have also been considered. A comparative study between polarized and conventional headlighting systems is performed under different situations. The performance metrics chosen for this purpose are visibility and glare.
