Abstract
Driver performance on curves was investigated using a driving simulator. Between-trial factors were blood alcohol level and type of driving scenario (eventful vs uneventful); within-session factors were edgeline width, type of curve-warning sign, and curve type. 12 men (aged 21-55 years) drove continuously for two hours on each of three nights. Curve-entry speed increased as radius of curvature increased. Lateral position error was greatest on the curve with the smallest radius and least on the curve with the shortest length. Heading error first increased then decreased as curve radius increased. Results are attributed to the absence of lateral-acceleration cues in the driving simulator. (A)
