Learning to interpret novel eHMI: The effect of vehicle kinematics and eHMI familiarity on pedestrian’ crossing behavior

•Investigation of how kinematic information and eHMI designs affect pedestrian crossing behaviours.•Comparison of how quickly a novel light-based eHMI and a more conventional Flashing Headlights eHMI were learned.•FH led to earlier crossings than the novel eHMI.•It took participants longer for the novel eHMI to affect crossing behaviour, indicating a longer learning process.•eHMI visibility was not the only reason for earlier crossings, with message familiarity playing a role.
