Improving External Communication of Automated Vehicles Using Bayesian Optimization

Exploring foci of: doi.org Improving External Communication of Automated Vehicles Using Bayesian Optimization April 2025 • Mark Colley, Pascal Jansen, Mugdha Keskar, Enrico Rukzio The absence of a human operator in automated vehicles (AVs) may require external Human-Machine Interfaces (eHMIs) to facilitate communication with other road users in uncertain scenarios, for example, regarding the right of way. Given the plethora of adjustable parameters, balancing visual and auditory elements is crucial for effective communication with other road users. With N=37 participants, this study employed multi-objective Bayesian optimization to enhance eHMI designs and improve trust, safety perception, … Open Article Page
