A Multi-Level Framework of Smart Transportation Adoption: A Systematic Literature Review of the Extended UTAUT2 Model using Weight Analysis

Abstract

Given the continuing global attention on smart transportation, the integration of mobile applications within smart transportation has become increasingly indispensable, not only in the realms of smart city governance but also mainstreamed across various Sustainable Development Goals (SDGs). The existing literature in this field, however, lacks a thorough examination of the various factors embedded in technology acceptance models and does not extend the context-specific variables in the model. Therefore, further academic attention is warranted. This systematic literature review (SLR) endeavours to bridge these gaps by categorising and systematising the existing literature, adopting the Extended Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model as a framework within the context of smart transportation. Firstly, a weight analysis was used to discern the significance of each predictor and determine their interactions. Furthermore, this study addresses the impacts of various factors on users' behavioural intentions in this specific context across different themes (technological, personal, and environmental). Finally, the modified extended UTAUT2 was mapped to smart transportation context dimensions to identify the limitations of current technology adoption research and provide a multi-level framework for future research with a broad spectrum of context dimensions. Overall, the study contributes to the existing theoretical frameworks by providing valuable insights, new perspectives, and alternative possibilities for further exploration. Practical advice is also offered to policymakers and researchers seeking to improve the adoption and effectiveness of mobile applications in the dynamic landscape of smart transportation.
