Vehicle-mounted sensors willsoon be capable of sensing such hazards in real time. This report addresses the design of a driverinterface to provide information about such hazards in a timely and cogent manner in order to allowattentive, distracted, or drowsy drivers enough time and information to avoid the hazard. An interfacethat consists of an auditory warning and an optional supplementary overlay of the hazard on a driver\ue2\u20ac\u2122seyeview of the roadway is recommended. A set of equations are developed that indicate when thedriver must begin applying either a pre-determined level of braking or a pre-determined level of addedlateral acceleration to avoid a perceived hazard
