Trust-building in L4 Automation by Intent Communication: Using HMI Design to Examine Passengers' Trust and Acceptance of Automated Vehicles

The rapid advancement of automated vehicle (AV) technology requires effective communication between AVs and their passengers to foster trust, perceived safety, and acceptance. This project explores how intent communication via Human-Machine Interfaces (HMIs) affects passenger trust in SAE Level 4 AVs. Using a driving simulator, two interface designs will be tested for their ability to convey vehicle sensing, navigation, and control intent. Outcomes include quantitative and qualitative data on passenger trust, usability, and technology acceptance, with the potential to inform HMI development for broader AV deployment. The findings aim to enhance AV adoption, improve passenger experience, and support safer integration of automated systems into transportation networks.
