Automation Effects on a Driver's Vigilance in the Automated Highway System, Volume 1. Final Report
Abstract
The Automated Highway System is part of efforts to introduce high levels of automation into motor vehicles. Anticipated benefits of this automation include improved highway safety and increased highway capacity. Operator vigilance is essential in highly automated environments such as cockpits and nuclear power plant control rooms. Increased vehicle automation may also require increased driver vigilance. Results of laboratory vigilance studies suggests that human performance on vigilance tasks decreases over time. Results of operational vigilance studies indicate that there may be an interaction between vigilance performance and the minimum level of acceptable task performance. In some situations a vigilance decrement may be operationally significant; in others it may be operationally insignificant. In addition, lessons learned from experience with high levels of automation in other environments directs attention to the importance of operator mental workload and situation awareness.
