Abstract:
Previous research on external Human-Machine Interfaces (eHMI) has primarily focused on interactions between automated vehicles and pedestrians. So far, little attention has been paid to the cyclist as vulnerable interaction partner. Compared to pedestrians, interactions with cyclists are usually much more dynamic and might, therefore, lead to different requirements for eHMI systems of automated vehicles. This study provides the first investigation on the effect of eHMI signals on cyclists’ behavior during dynamically evolving interactions. Using a bicycle simulator, 20 participants encountered different interactions with automated vehicles with and without eHMI. The eHMI used light strips to communicate its maneuver intention to brake or continue driving. When the automated vehicle braked, the eHMI supported the effectiveness and efficiency of cyclists’ behavioral decisions. However, when the vehicle continued driving, the eHMI provoked three critical situations where cyclists approached the vehicle with a distance of less than one meter. In conclusion, the eHMI had both positive and negative effects on cyclists’ behavior. As a perspective for future research, we recommend systematically comparing the effects of eHMI systems on behavioral decisions of pedestrians and cyclists. Future eHMI systems should be able to support all vulnerable road users equally.
