Scalability in External Communication of Automated Vehicles

Automated vehicles will alter traffic fundamentally. While users can engage in non-driving-related tasks such as reading or even sleeping, the possibility to interact with other road pedestrians via, for example, eye contact vanishes. Therefore, external communication of automated is currently researched various concepts spanning dimensions anthropomorphism, technology, viewpoint, locus, message type, and others. However, proposed are mostly evaluated simple scenarios, one person trying cross front vehicle. we implemented a WebGL application four-lane conducted within-subject study (N=46) effects nine without presence altering yielding target We found that all were rated better than having no communication. not uniform across concepts.
