1. Data processing means for generating highway traffic collision avoidance advisories or commands in which actual vehicle accelerations or decelerations are determined by means for differentiating a continuous time series of vehicle velocity measurements and required collision avoidance decelerations are determined by means for dividing twice the distance between an individual vehicle and a potential obstacle into the square of the difference in velocity between the individual vehicle and the potential obstacle, means for algebraically adding this quantity with the sign of the velocity difference retained to the actual acceleration or deceleration of the potential obstruction and means for generating collision avoidance advisories or commands when the required collision avoidance decelerations exceed actual vehicle decelerations.
