V2Cyclist: The V2X protocol as a carrier of information

Goal

The overarching goal was to explore and demonstrate how V2X communication can serve as an effective information carrier between vehicles and cyclists.

Challenge

The development of wireless communication in traffic environments today largely focuses on motor vehicles. There is a need for research and development specifically targeting the conditions and needs of cyclists. The challenge in the project involved finding a technical solution that meets the requirements for data transfer, size, and power supply. Additionally, it involved creating a user interface that effectively informs the cyclist without being annoying or unnecessarily distracting. 

Solution

The project resulted in two prototypes using different technical architectures to communicate information between cars and cyclists. One prototype utilized direct communication via V2X, while the other used communication via the mobile network. The prototypes could warn the cyclist about two common risks in traffic environments. In one of the prototypes, the car driver also received a warning. Furthermore, user interfaces designed for integration into a bicycle helmet were developed and tested. In the interface, the cyclist receives information through sound and vibrations via bone conduction speaker elements. This solution allows the cyclist to hear the surroundings since the elements do not cover the ears. Utilizing the helmet as an interface could also potentially contribute to increased use of bicycle helmets in the future. The project's studies and demonstrations showed that the solutions have promising potential to increase traffic safety and be accepted by users.

Effect

Insights generated by the project could, in the long term, lead to improved traffic safety and continued appeal of cycling as a mode of transportation. Thus, the project has contributed to the promotion of sustainable cities and communities, health and well-being, as well as combating climate change.
