Abstract
Autonomous (self-driving) vehicles have been predicted to start arriving on roads in the very near future. Despite concerns over how self-driving vehicles will integrate into human-driven traffic, little empirical work has examined interactions between autonomous vehicles and human drivers. With this in mind, this thesis presents two complimentary streams of research which examined the psychological factors influencing evaluations of autonomous vehicles and computerised systems. The first stream consisted of two sets of driving simulator experiments which looked at perceptions of autonomous overtaking manoeuvres and occupant satisfaction during autonomous highway journeys. Overall, these experiments revealed that occupants and other road users are very sensitive to the driving style of the autonomous vehicle itself, with a smaller influence of traffic context, which sometimes resulted in autonomous vehicles being evaluated more negatively due to the behaviour of other drivers. The second stream consisted of two sets of laboratory-based experiments, which applied findings on the influence of relative ranking and framing on decision making to trust of computerised systems. Overall, this second stream found that users’ evaluations were very sensitive to the accuracy of systems, slightly sensitive to some contextual factors, with little or no influence of framing or rank-based effects. Across both streams, the findings of this thesis suggest a limited degree of sensitivity to contextual factors when evaluating the behaviour of autonomous vehicles and computerised systems. The results are discussed in terms of implications for psychological theory and practical considerations for the introduction of autonomous vehicles.
