A quantitative technique, based upon driver visual search performance and driver control performance was developed to quickly evaluate the potential accident-reduction effectiveness of illumination designs. Six subject drivers drove an instrumented vehicle through nine intersections with known night accident rates, during both day and night. Drivers' visual search patterns (fixation times, distribution of fixations in the road scene, visual spatial and temporal activity) and driving control measures (e.g., velocity and steering) were recorded and analyzed. Results indicate different patterns of driver behavior at high and low accident-rate sites which may be useful for determining effectiveness of illumination. Behavior at illuminated sites improved to more closely resemble day time driver behavior.
