Self-driving vehicles are one of the innovative applications of artificial intelligence (AI). On-road experiments with self-driving buses are conducted around the world. This study focuses on Level 4 self-driving buses. We explore decision-making factors of potential users who are faced with a ethical dilemma situation by using a cusp catastrophe model. This study collects data through questionnaire surveys in Taipei and Shanghai. Results of the two cities are compared. We find that 47% of the respondents find it acceptable to allow a ''human driver'' or an ''AI algorithm'' to control the Level 4 self-driving bus when faced with a ethical dilemma. However, they prefer ''human drivers''. In addition, respondents in Taipei perceive a higher usefulness of self-driving buses and have more positive attitudes toward them than respondents in Shanghai. The latter exhibit higher perceptions of risk and behavioral control. In addition, we conduct a qualitative analysis based on a cusp catastrophe model. The results of this study can serve as a reference for government authorities seeking to formulate policies for promoting self-driving buses. |
