This Traffic Tech describes the findings of a project that evaluated the efficacy of two notifications, a lane departure warning (LDW) and a drowsiness notification with LDW (DN/LDW), on potential drowsy driving episodes during 4-hour overnight drives in a driving simulator with an incentive designed to replicate motivational tradeoffs common to drowsy driving. The combined DN/LDW was effective in reducing the frequency of lane departures and in reducing percentage of eyelid closure prior to lane departure events compared to baseline. There was no difference between the notification conditions and baseline with respect to the frequency or timing of breaks to rest.
