Augmentation Concepts with HUDs for Cyclists to Improve Road Safety in Shared Spaces

Exploiting the potential of automated vehicles and future traffic concepts like platooning or dynamic intersections requires the integration of human traffic participants. Recent research investigating how automated vehicles can communicate with other road users has focused mainly on pedestrians. We argue that cyclists are another important group of vulnerable road users that must be considered, as cycling is a vital transportation modality for a more sustainable future. Within this paper, we discuss the needs of cyclists and claim that their integration will demand to think of other concepts, which support moving communication partners. We further sketch potential approaches for augmented reality applications based on related work and present results of a pilot study aiming to evaluate and improve those. Initial findings show that people are open towards concepts that increase cyclist safety. However, it is key to present information clearly and unambiguously to produce a benefit.
