Autonomous buses promise to improve safety and accessibility in our traffic systems. Because it is a new technology it can be challenging to achieve good adoption rates. In one experiment we examine how psychological factors linked to general adoption of new technology relates to adoption of autonomous buses. Participants (N = 89) report their curiosity and expectations on the behavior of an autonomous bus approaching a pedestrian crossing. Performance expectancy and trust towards autonomous buses are also measured. Results indicate that Performance expectancy and trust are important factors for stimulating behavioral intention to use autonomous buses.
