The Effect of Wide-Angle Headlight Illumination on Driver Performance

摘要

The purpose of this study was to identify possible improvements in the present U.S. low beam headlight system, using an instrumented passenger car to evaluate the effect of experimental wide-angle low beam lighting on various driver performance measures--speed, brake pressure, longitudinal acceleration, steering wheel position, lateral acceleration, lateral lane position, and electrodermal response (GSR), for over 1,000 vehicle miles (30 hours) on a winding rural highway at night.
