Key factors capturing the willingness to use automated vehicles for travel in China

This paper designs an online stated preference (SP) survey to investigate the intention to use autonomous vehicles among the study participants in China. It took 3 months to collect 1,248 valid questionnaires at the end of December 2022. Based on this, an ordered Probit model with random parameters is constructed to assess the effects of social informativeness, perceived ease of use, perceived usefulness, and perceived risk of autonomous vehicle usage intention, and to explore the effects of personality as an intermediate variable on the above four dimensions.
