5G Connected Autonomous Vehicle Acceptance: The Mediating Effect of Trust in the Technology Acceptance Model

Abstract

The purpose of this paper is to examine the factors that influence the behavioural intention towards 5G connected autonomous vehicle (CAV) adoption and to examine the mediating effect of trust between the factors and public acceptance. This research has adopted the Technology Acceptance Model (TAM) and Unified Theory of Acceptance and Use of Technology (UTAUT) framework. To test the hypotheses, 211 participants in Malaysia were surveyed through an online questionnaire. The results were tested using PLS-SEM. The research model was able to explain about 69% of the variability in technology acceptance. The results show that perceived compatibility and personal innovativeness significantly influence behavioural intention. Trust was found to mediate the relationship between perceived usefulness, perceived ease of use and social influence with behavioural intention to adopt 5G CAV. This paper will help the automobile industry and policymakers to accelerate the development of 5G CAV technology by anticipating the level of acceptance.

A study on psychological determinants of users' autonomous vehicles adoption from anthropomorphism and UTAUT perspectives

“…However, perceived value is not shown to be a significant mediator between system factors and the adoption of AVs. A possible explanation is that system factors are more associated with trust of AVs (Chan and Lee, 2021 ) while UTAUT factors are more associated with the perceived value of AVs. In the future, researchers can explore other mediators to more deeply investigate the relationship between system factors and adoption of AVs.…”

Analysis of Engineering Students Acceptance and Usage of 5G Technology: A Case Study of Gannon University

“…This analysis considered only perceived ease-of-use and perceived usefulness to see the user's actual usage of 5G technology. Where in a previous study (Akbari et al, 2020;Chan & Lee, 2021;Han & Zhang, 2020), additional factors like perceived enjoyment, perceived personal innovations, perceived skills readiness, etc. The sample size is smaller and is only focused on the engineering students at Gannon University.…”

“…Furthermore, from the recent development in VR technology, now there is software that enables people to be virtually present at the office or in project meetings. For instance, a tool that was developed by Facebook called Metaverse that allows users to connect virtually (Chan & Lee, 2021).…”

“…Perceived compatibility is used to indicate whether the new technology is fit for day-to-day use. The use of 5G CAV for their daily commute is considered with this parameter (Chan & Lee, 2021). A social influence is a measure to see if the user's intention is driven by the influence of other family members or friends due to the community.…”

“…However, conclusive findings require further analysis of the additional factors. In a study by Al-Maroof et al (Al-Maroof et al, 2021) and Chan and Lee (Chan & Lee, 2021), the impact of other factors apart from the perceived ease of use and perceived usefulness were considered. Moreover, from the education level graduate students have more average ratings for all 3 variables as compared to undergraduate students.…”
