ABSTRACT
This chapter examines driver workload during vehicle automation and the management of drivers' attention and awareness of the situation when automation fails. The discussion describes the sources of workload associated with manual driving and how different levels of automation can impact driver workload. We describe specific challenges associated with potential driver underload and overload conditions, including take-over (or handoff) situations where drivers' workload and attention levels can impact their ability to safely and quickly reengage in the driving task. Finally, we present future opportunities for managing attention and workload through innovative approaches to the conceptualization and design of the human-machine interface (HMI).
