To Alert or Assist: Comparing Effects of Different Lateral Support Systems on Lane-Keeping

This TechBrief describes an experiment examining the effect of lateral support systems on driving behavior and user acceptance of lateral support systems. The research team used a driving simulator to compare lane-keeping behavior when drivers were controlling the vehicle without lateral assistance (i.e., manual control) or were assisted by lane-departure warning (LDW) or lane-keeping assist (LKA) systems. The goal of the study was to assess the effect of each type of lateral support system on drivers’ lane-keeping ability in different situations and examine driver acceptance of lateral support technology.
