The main aim of this study was to use an adapted version of the UTAUT framework to investigate the social-psychological factors that influence users’ acceptance of an automated road transport system (ARTS). Results of our survey, conducted with users of ARTS in the city of Trikala, Greece, provide evidence of the usefulness of this framework for increasing our understanding of public acceptance of these vehicles. In particular, users’ enjoyment of the system plays a big part in their desire to use it again, while the performance of the system, the resources provided to support its use, and the social popularity of the system all appear to be important factors. It is hoped that in order to maximise system uptake, designers and developers of such automated systems can consider the above issues when implementing more permanent versions of automated public transport. The current findings build on previous research in La Rochelle in France, and Lausanne in Switzerland which suggest that similar factors are likely to have an influence in all three countries (Madigan et al., 2016), although the specific requirements for promoting user enjoyment, performance expectancy etc. may vary across cultures. From a theoretical point of view, a number of modifications to UTAUT are suggested for future use in understanding automated transport. These include the exclusion of the construct of effort expectancy, and the addition of price, public transport habits, and perceivedsafety.
