The role of attitudinal features on shared autonomous vehicles

The study aims at uncovering the effects of attitudinal features on Shared Autonomous Vehicles (SAVs) adoption from a systematic and comprehensive perspective. Specifically, the technology acceptance model (TAM) was employed to systematically propose three key factors, i.e., green perceived usefulness, perceived ease of use, and behavioral intention. The life-oriented approach (LOA) was employed to extend TAM comprehensively by identifying three determinants, i.e., relative advantage, environmental awareness, and perceived risk. The study established correlations between behavioral intention and five attitudinal variables. The structural equation model (SEM) was applied to interpret the effects of these determinants on SAVs adoption. The study conducted a survey in Nanjing, China, from May to June 2020, with 627 valid respondents, to validate the results. Results indicate the significant effects of attitudinal features on SAVs adoption. SAVs adoption is related positively to relative advantage (0.47), environmental awareness (0.22), green perceived usefulness (0.29), and perceived ease of use (0.16). Perceived risk (−0.33) negatively affects SAVs adoption. These findings provide implications for improving SAVs adoption and suggestions for future research by emphasizing the importance of attitudinal features.
