Several driver-performance factors contribute to rear-end collisions: driver inattention, perception/ reaction time, and limitations in the human visual system Although many evaluations have examined driver response to various Rear- end Collision Avoidance Systems (RECAS) display and algorithm alternatives, little research has considered creating a quantitative model of driver performance to evaluate design alternatives. Current considerations of driver behavior in developing warning algorithms tend to ignore the fundamental problem of driver inattention and assume a fixed driver reaction time with no further adjustment after the initial response. A more refined model of driver response to rear-end crash scenarios can identify more appropriate and timely information to be displayed to the driver. The driver's attention distribution, information extraction and judgement process and the reaction process are all incorporated into a conceptual model of the driver. The model developed predicts the closed- loop nature of collision response performance and explains how the driver might use RECAS warnings
