Towards C-ITS-based communication between bicycles and automated vehicles

Abstract

Cooperative Intelligent Transport Systems (C-ITS) technologies will play a significant role in the communication of automated vehicles. So far, vulnerable road users such as cyclists or pedestrians are often excluded from the communication and therefore are not able to actively create awareness for themselves. The Austrian research project Bike2CAV aims at improving bicyclists’ safety via Cooperative Intelligent Transport Systems (CITS) technologies. The work introduces the implemented prototype of a CITS- enabled helmet consisting of a GNSS (Global Navigation Satellite System) device (XSens MTi 680G) to determine the current location and two additional IMUs (MetamotionR by Mbientlab) mounted on the left and right hand to recognize turn intentions indicated by hand signals. The overall goal is to evaluate the C-ITS-prototype in real-world situations, especially whether localization accuracies (0.1 m accuracy at 95% confidence) can be achieved. For the LBS 2021 conference, first results will be available.
