Paper introducing the Autonomous Vehicle Acceptance Model (AVAM), a model of user acceptance for autonomous vehicles, adapted from existing models of user acceptance for generic technologies.

The AVAM questionnaire is used to assess current public perception of autonomous cars, with the model and questionnaire results intended to enable meaningful comparison between future studies of autonomous vehicles.
