DescriptionWhile drivers’ calibrated trust is indispensable for the safety of Automated Vehicles (AV) it is challenging to achieve. A critical first step to achieving calibrated trust is to develop measures that are sensitive to trust dynamics. These measures must be sensitive to the specific trust dynamics found in AV and they must consider the fact that trust is multi-dimensional. Identifying these measures requires novel experimental protocols, measurements, and analyses. The goal of this paper is to discuss a decision process to develop an experiment to measure dynamic trust in AV that is grounded in the literature and real-world observations and present pilot data to illustrate feasibility. The findings of this paper can be used as a guide for researchers and designers for future user studies.
