Abstract—To determine whether external human–machine interfaces (eHMIs) make pedestrians careless toward the traffic environment, we examined the following four hypotheses: H1, the pedestrian decides to cross earlier after seeing a yielding message on an eHMI; H2, the pedestrian perceives safety after seeing a yielding message on an eHMI; H3, the pedestrian’s confirming behavior before crossing is suppressed after the pedestrian sees a yielding message on an eHMI; H4, miscommunication between pedestrians and automatic vehicles can be caused by yielding messages on an eHMI.
