This research investigated the effectiveness of prototype lighted guidance devices (LGDs) in a virtual environment that manipulated optical flow and environmental cues to influence covertly drivers' perception of velocity and thereby indirectly modulate vehicle speed. Experiment 1 examined the effects of driver age, driver sex, light pulse characteristics (all on; all of; 50 mph forward, 5on:5off, 50 mph forward, 7on:3off); speedometer feedback; and vehicle location within the work zone. Despite age and sex differences, 24 drivers showed vehicle acceleration throughout the work zone associated with forward pulsing lights compared to control conditions. Experiment 2 investigated the effects of driver sex, light pulse direction (forward 25 mph, backward 50 mph, and stationary), light color (red and green), zone entry speed (40 and 70 mph), and location within the zone on vehicle speed and lane tracking for 24 drivers (12 male and 12 female). Results replicated those of Experiment 1 showing vehicle acceleration to forward pulses and also slowing to backward pulses plus a slight advantage of green lights compared to red and white lights. Without explicit instructions or signage, LGDs modulated actual vehicle speed: green lights atop jersey barriers pulsed in a forward direction at greater than or similar 25 mph increased the speed of vehicle entering the zone at less than or similar 40 mph and backward pulsing lights at greater than or similar 50 mph decreased the speed of vehicles entering the zone at 70 mph.
