The aim of this pilot study was to evaluate the effect of training on passengers' understanding and acceptance of an automated function used for a bus entering and exiting a bus stop. An HMI were used to inform the passengers that the bus was in automated mode. This was done with activation of lights in led strips around the steering wheel and the front window, together with an informative sound. The study used a virtual reality platform to simulate the scenario. 

Twenty participants took part in the study, with an equal balance between female and male passengers, and an age range of 25-60 years. Half of them participated in a training session, watching a short informative film, learning about the HMI and how to behave when approaching the bus. Data was collected using positioning in the simulation, eye tracking, various questionnaires, and a short interview. 

All participants who received the training found it useful. From the debriefing interview it was clear that the training did increase the understanding of the system, but no significant effects of the training were found in behavior or in acceptance.
