As automated road vehicles begin their deployment into public traffic, they will
need to interact with human driven vehicles, pedestrians, bicyclists, etc. This
requires some form of communication between those automated vehicles (AVs) and
other road users. Some of these communication modes (e.g., auditory, motion)
were previously addressed in “Unsettled Issues Regarding Communication of
Automated Vehicles with Other Road Users.”
Unsettled Issues Regarding Visual Communication Between Automated Vehicles
and Other Road Users focuses on visual communication and its balance
of reach, clarity, and intuitiveness, and discusses how different visual modes
(e.g., simple lights, rich text) can be used between AVs and other road users. A
particular emphasis is put on standardization to highlight how uniformity and
mass adoption increase communication efficacy.
