Risk-Taking Driving Behavior in Interacting With an Autonomous Vehicle at Two-Way Stop-Controlled Intersections

During the initial stages of autonomous vehicles (AVs), they will coexist and interact with human-driven vehicles (HVs). There is a research gap in exploring AVs' impact on human drivers' risk-taking driving behaviors during such interactions. A questionnaire survey was conducted among 676 drivers to gain insight into this impact. Respondents were asked to complete the questionnaires after understanding the scenarios of interacting between HVs and AVs at two-way stop-controlled intersections. The results demonstrate that human drivers have higher risky driving intentions and perceive lesser social pressure and safety risks when interacting with AVs compared to HVs interactions. Attitudes are the most important factor in explaining risk-taking driving intentions. Furthermore, intentions are directly influenced by perceived behavioral control when interacting with AVs. These findings indicate that human drivers may engage in risky behaviors when interacting with AVs.
