Automated-Manual Transitions: Human Capabilities and Adaptive Cruise Control
This report describes a study in which the authors examined the conditions required for a graceful automated-manual transition resulting from the use of adaptive cruise control (ACC). Focus is on two features of the human operator: 1) the visual capabilities required by the human operator to determine the need to assume manual control, and 2) the features of an in-vehicle warning signal, initiated by either a lead vehicle or a following vehicle, that could reliably prompt appropriate human operator action. This was accomplished by the following tasks: 1) a literature review that identified the visual cues that prior research identified as likely being the most important to human observers in detecting and avoiding impending collisions; 2) development of laboratory microsimulation of the lead vehicle braking scenario; 3) laboratory studies of cues to headway change judgment; and, 4) false alarm studies.
