The Analysis on Drivers' Visual Perception Affected by Blocking Vehicle's Taillights

摘要

The number of chevrons that is in sight at one time will affect drivers' perception accuracy of road curvature. By the experiment of sight blockage, this paper studies the influence of outer-lane blocking vehicle's taillight, on the drivers' perception accuracy of road curvature. The experiment takes advantage of Zwahlen and Park's monocular viewing experiment. Under the condition of vehicles blocking inside drivers' sight, this paper analyses the space distributing type of the chevrons and blocking vehicle on the testing curves, and it performs an experiment of different types by random sequence. The experiment results and comparing analysis between sight blocked and unblocked indicate that, the truck's taillight has beneficial effects on blocked drivers' accurate perception of the curve, but the effect is less than chevron.
