This experiment (number 3 in a series) investigated the effects of pulsing lights, which gave the illusion of movement (Phi phenomenon), on drivers' perception of motion and vehicle speed through work zones. Forty drivers participated: 20 young (10 female, 10 male; 21-42 yrs) and 20 older adults (10 female, 10 male; 55-87 yrs). Each participant made 15 passes through a work zone in the virtual world of a driving simulator: a control pass with stationary white lights, two control passes with no lights, and 12 passes of test conditions - 2 colors (red & green) x 3 apparent pulse speeds (-80, 0, & +80 mph) x 2 zone entry speeds (40 & 70 mph). Age, sex and zone entry speed differences were found, but overall, backward moving lights (-80 mph) caused drivers to reduce their vehicle speed, forward moving lights (+80 mph) caused drivers to increase their vehicle speed, stationary light and control lights had little or no effect, and green produced stronger effects than red.
