Predictive Power of Pre-Trial Perceptions and Attitudes on Autonomous Shuttle Adoption Intention : Evidence from South East Queensland

This study is focused on perceptions and attitudes regarding autonomous shuttle adoption for shared demand-responsive transit (ASDRT) services. There is presently limited understanding of public perceptions and attitudes towards the adoption of ASDRTs. To address this gap, a theory-based conceptual framework is proposed to provide detailed empirical insights into the public’s adoption intention towards autonomous shuttle buses (ASB) as a form of ASDRT. Relationships between seven factors (perceived usefulness, perceived ease of use, attitude, usage intention, perceived risks, perceived relative advantages, and perceived service quality) are examined employing a partial least squares structural equation modelling method. The results support the basic Technology Acceptance Model casual relationships that correspond with former studies. Regarding perceived relative advantages and perceived service quality, our findings specify their significant role in forming favourable attitudes toward ASBs, but do not necessarily lead to a boost in usage intention. Conversely, perceived risks are shown to have no association with perceived usefulness but negatively impact travellers’ attitudes and usage intention towards ASBs. Practical implications are also presented to assist policymakers in planning future sustainable travel behaviour
