To ensure road safety, automated vehicles (AVs) should be able to act and react to vulnerable road users (VRUs). External human-machine interfaces (e-HMIs) may allow AVs and VRUs to communicate effectively. We investigated the effects of various light signals presented by a light bar placed on the test vehicle’s roof (i.e. e-HMI). In addition, the driver was visible or the car appeared driverless by using a seat suit that covered the driver (Wizard-of-Oz design). A total of 173 random pedestrians passing by were interviewed. Participants felt significantly safer during the interaction with the vehicle when a driver was visible, while they evaluated the presented light signals as only partially trustworthy and unintuitive to understand. However, participants evaluated the application of light signals as e-HMIs for AVs as generally useful.
