Book excerpt: This text presents a four-step approach for applying communicative concepts to driving automation, including: scoping, piloting, designing, and testing. It further provides experimental data on how practical human-human communication strategies can be applied to interaction in automated vehicles. The book explores the role of communication and the nature of situation awareness in automated vehicles to ensure safe and usable automated vehicle operation. It covers the issue of interaction in automated vehicles by providing insight into communicative concepts, the transfer of control in human-teams, and how these concepts can be applied in automated vehicles. The theoretical framework is built on by presenting experimental findings, design workshop output and providing a demonstration of prototype generation for automated assistants that addresses a wide range of performance outcomes within human-machine interaction. Aimed at professionals, graduate students, and academic researchers in the fields of ergonomics, automotive engineering, transportation engineering, and human factors, this text: Discusses experimental findings on how practical human-human communication strategies can be applied to interaction in automated vehicles. Provides a four-step approach for applying communicative concepts to driving automation, including: scoping, piloting, designing and testing. Explores the role of distributed situation awareness in automated vehicles. Covers communication and system awareness in response to multiple complex road scenarios. Provides design guidelines for automation-human handover design.
