EVALUATION OF HUMAN FACTORS AND SAFETY PERFORMANCE IN THE LONGITUDINAL CONTROL OF HEADWAY

This paper presents findings from a study pertaining to human factors issues and safety-related performance as derived from operating a passenger car equipped with an autonomous/intelligent cruise control (ACC) system for controlling headway in typical freeway traffic. The findings are based upon results of objective measurements and subjective responses obtained from a set of 36 naive drivers. These driver/participants were selected to provide a sample of the motoring population, which varied in age, gender, and experience with conventional cruise control (CCC). Measurements of performance and subjective responses are evaluated and compared for periods of vehicle operation involving normal manual driving, CCC, and ACC. Objective measurements of range to the preceding vehicle, the time rate of change of that range, and the velocity of the base vehicle are used to examine performance during situations involving closing on a vehicle ahead, following a preceding vehicle, and reacting to sudden merges or cut-ins by other vehicles. The measures used to evaluate performance include minimum range and the headway time. Objective measuremente are also used to determine the frequency and amount of brake and accelerator application by the driver. These measurements are used to study normal driving as well as the supervisory role of the driver during CCC or ACC.
